if "R"= red and I assume non dominat color is white then "r"-white if "S"= smooth seed and "s"- wrinkled Your plant would be "Rrss" = Red flowers, but produces wrinkled seeds

A pea plant with round seeds has the genotype Rr you cross this plant with a wrinkled seed plant genotype rr what is the probability that the offspring will have wrinkled seeds?
To figure this out, use a Punnet Square.First, set up a test cross, like this:Rr x rrThis shows what you are crossing. Now you can make a Punnet Square.R rr Rr rr There is a 50/50 chance that the corn plant will have thegenotype rr.r Rr rr
If a plant has round seed and the genotype Rr the ''r'' stands for what?
The little r stands for a recessive wrinkled trait.
Why do you think it was important for Mendel to study only one trait at a time during his experiments?
He didn't just study one trait at a time he studied single gene traits, with clear dominance versus recessiveness. Single genes produce genotype ratios 1:2:1 & phenotype 3:1 He did study dihybrid crosses where he tracked two single gene, unlinked traits. Dihybrid ratio genotype pattern is 1:4:6:4:1 while the phenotype is 9:3:3:1 Mendel's peas were domesticated with easily distinguishable single gene phenotypic traits (short vs tall; wrinkled vs round; greed seeds vs yellow seeds). Peas only have 7 pairs of chromosomes and Mendel used 7 visibly distinct, single gene traits that assort one to a chromosome pair. Each trait he studied shoed complete dominance, not with blended (incomplete dominance), or checkered (codominance). The difference is that single gene traits are controlled by the alleles for just one gene. Not all traits are single genes however. Most traits are polygenic, influence by multiple genes. Polygenic traits do not produce progeny with clear whole number ratios for each version. Instead the progeny show a normal distribution curve where most progeny have the average value but the are individuals at each extreme. It was the good sense or good fortune that Mendel did choose to study single gene traits so he could discover the ratios that provide the evidence for his laws of inheritance.
What are the characteristics of a garden pea?
Mendel looked at seven different characteristics of the pea plants he experimented with. These were: - flower colour (white or purple) - flower position (axil or terminal) - stem length (short or long) - seed shape (round or wrinkled) - seed colour (green or yellow) - pod shape (inflated or constricted) - pod colour (green or yellow) He illustrated that some traits are hereditary, they are passed on to the next generation.
What causes the physical changes that occur between childhood and adulthood?
Late adulthood is the period of life in every individual that follows the period of his or her life after he/she turns 60 years of age. This period is marked by the process of growing old, resulting in part from the failure of body cells to function normally or to produce new body cells to replace those that are dead or malfunctioning. This in turn results in significant physical, psychological, and cognitive changes, like cardio-vascular, digestive malfunctioning, depression, impaired memory functioning, and so on. In this article, we shall have a look at the major changes in these categories. Physical Changes In The late Adulthood: The physical changes that occur in the bodies of the individuals, in their late adulthood can be divided into two main categories-External Changes- These changes are the outward signs of aging, and are quiet obvious to notice. They consist of changes in hair, skin, posture etc. Most people's hair becomes distinctly gray and eventually turns white, and it may also thin out.The skin becomes less elastic, more wrinkled, dry, and thin. The wrinkles are formed partly because of loss of fatty tissue under the skin and partl Anxiety Disorders-Anxiety Disorders is significant conditions in the elderly population. Dementia is broad category covering several diseases, each of which include serious memory loss accompanied by reduction in other mental functions. The blood vessels become less elastic and some become clogged resulting in fewer capillaries, delivering blood to the entire body. Heart and Lungs-Due to hardening and shrinking of blood vessels in the body, the heart is forced to work harder, and it is typically unable to compensate fully. The most serious deficits occur in vision and hearing. The anxiety disorders most prevalent in old people include panic disorder, phobias, obsessive-compulsive disorder, generalized anxiety disorder, acute stress disorder, and post-traumatic stress disorder (PTSD. Other Psychological ProblemsThere are several other psychological challenges faced by the older people, which include mood disorders, schizophrenia, etc. 2) Internal Changes- As the outward physical signs of aging become increasingly apparent significant changes occur in the internal functioning of the organ systems. Though mood disorders are seen more commonly (4. Also, it could be partially due to changes in posture. Psychological Changes In The Late Adulthood-- With the advancing age, along with several physical changes, there are also certain psychological changes occurring, in the older people. As the old people become more depressed, their perceived health decreases, their ability to function and sense of mastery, and sense of contentment diminishes.
Dominant wrinkled pea recessive smooth pea?
Wrinkled peas are recessive, smooth peas are dominant.
What is the genotype of the offspring that do not share the parents phenotype?
Genotype is the coded for traitPhenotype is the visible characteristicSo in the case where both parents had heterozygous dominant Brown eyes (Bb - big B for brown, dominant gene; little b for blue recessive gene); it is possible for the child to have blue eyes, by being homozygous recessive (bb).However this is an educated guess, as your question does not make sense.
In Mendel's experiment why did wrinkled seeds show up in the F2 generation even though they were not present in the F1 generation?
Wrinkled seeds are recessive The F1generation carried recessive alleles.
What is an organism that is heterozygous for two traits?
An organism that is heterozygous for two traits means that it contains both the dominant allele and the recessive allele for both of the traits in question. For example, take a plant that produces peas. The gene that produces yellow seeds (denoted Y) is dominant, the gene for green seeds (y) is recessive. The gene that produces round seeds is dominant (R), the gene for wrinkled seeds (r) is recessive. So if this organism was heterozygous for both traits its genotype would be: Yy/ Rr Which means it has the allele for yellow seeds and the allele for green seeds (trait one), and also has the allele for round seeds and the allele for wrinkled seeds (trait two). Its phenotype (the traits it displays) will be yellow round seeds, as these are the dominant traits.
In pea plants are round or wrinkled seeds dominant?
In pea plants round seeds are dominant to wrinkled. So to have round seeds you either will have two dominant alleles (homozygous dominant) or one dominant and one recessive allele (heterozygous)
What does dihybrid heterozygous mean?
"Heterozygous" means having one copy each of the dominant and the recessive allele governing a particular trait."Dihybrid" means that you are following the inheritance of two traits ("di-" = 2).For example: in the peas that Mendel studied, round seeds (allele R) are dominant over wrinkled (r). So a heterozygous plant has the genotype Rr. Yellow seeds (Y) are dominant over green (y). In experiments following these two traits (seed shape and seed color) a dihybrid heterozygous individual therefore has the genotype RrYy.A dihybrid cross involves observation of two traits, e.g.RRYY x rryywhich would yield an F1 entirely made up of RrYy individuals.
What is the probability that a offspring will have wrinkled seeds?
R represents the dominant round allele, and rrepresents the recessive wrinkled allele. :D
A pea plant with round seeds has the genotype Rr you cross this plant with a wrinkled seed plant genotype rr what is the probability that the offspring will have wrinkled seeds?
To figure this out, use a Punnet Square.First, set up a test cross, like this:Rr x rrThis shows what you are crossing. Now you can make a Punnet Square.R rr Rr rr There is a 50/50 chance that the corn plant will have thegenotype rr.r Rr rr
If a plant has round seed and the genotype Rr the ''r'' stands for what?
The little r stands for a recessive wrinkled trait.
What is the genetic nature of wrinkled phenotype of pea seeds?
As stated in mendelian inheritance wrinkled seeds have recessive trait(r),while round seeds are dominant trait(R).
What is the principle of dominance?
The Principle of Dominance states that some alleles are dominant and some alleles are recessive. The dominant trait dominates or presents the expression of the recessive trait. Thus, for round seed: (capital) R - round (small) r - wrinkled RR - pure round Rr - hybrid round rr - pure wrinkled
What is heterozygouz?
Many organisms contain two copies of each chromosome, and generally these two chromosomes are not identical. If a particular trait, such as the shape of a pea, is determined by one particular section of a chromosome, it is possible for the two copies of the chromosome to have different instructions for the trait. If the two sections of the two chromosomes have different instructions, this is called being heterozygous.Often if an organism is heterozygous for a trait, one of the sets of instructions (called an allele) will be dominant over the other. This means that if either of the chromosomes has that dominant version of the allele, that is the set of instructions that will be followed.Examples: The gene for seed shape in pea plants exists in two forms, one form or allele for round seed shape (R) and the other for wrinkled seed shape (r). A heterozygous plant would contain the following alleles for seed shape: (Rr).Organisms have two alleles for each trait. When the alleles of a pair are heterozygous, one is dominant and the other is recessive. Using the previous example, round seed shape (R) is dominant and wrinkled seed shape (r) is recessive. Round: (RR) or (Rr), Wrinkled: (rr).
