What is the difference between a genotype ratio and a phenotype ratio?

The genotype is the actual code for a trait. Hidden on the chromosome we can never actually see the alleles controlling the trait unless we sequence the DNA. The phenotype is the result of at least two alleles expressing a visible or measurable trait in an individual. A genotype to phenotype ratio is the correspondence between the unseen code of the individual's alleles and the detectable quality of the individual's trait. This ratio relates the proportional quantities of unseen and seen, a comparison between the encoded trait and the expressed result of the code.

∙ 13y agoLet's start at the beginning. A genotype is the allele combination for a specific trait. For example, the trait you inherit from your parents for tallness; the genotype may be Tt. The phenotype is the physical appearance. For example, long brown hair, blue eyes, etc.
A phenotypic ratio is a ratio comparing the possible outcomes for an organism based on physical appearance. For example. you may complete a Punnett Square and your outcome is 3 purple : 1 white. This is your phenotypic ratio for flower color. (As an example)
The genotypic ratio is the comparison of genetic information, the frequency. This can be expressed as 2:1:1 as an example of a ratio.

What is the expected phenotype ratio of seed color of the offspring of an F1 x F1 cross?
If the parents were AA and AA for example then the phenotype ratio will be 1 A (the dominant allele). The genotype will be 1Aa.
When crossing a Rr genotype with a rr genotype what will the ratio of RR to rr be in the resulting generation?
50%Rr to 50%rr
What is the phenotype ratio of a cross between a heterozygous male and female?
The phenotypic ratio is a 3:1 ratio.
To determine the genotype of an individual that shows the dominant phenotype you would cross that individual with one that is?
To determine the genotype of an individual that shows the dominant phenotype you would cross that individual with one that is homozygous recessive. A monohybrid cross of two individuals that are heterozygous for a trait exhibiting complete dominance would probably result in a phenotype ratio is 3 dominant 1 recessive.
What will be the phenotype ratio of the offspring?
9:3:3:1 is the phenotypic ratio of the offspring.
What would be the phenotype ratio and genotype ratio in the offesprings in the f2 generation?
For monohybrid cross the genotype ratio in f2 generation would be 1:2:1 and phenotype ratio would be 3: 1
What is the expected phenotype ratio of seed color of the offspring of an F1 x F1 cross?
If the parents were AA and AA for example then the phenotype ratio will be 1 A (the dominant allele). The genotype will be 1Aa.
What is the genotype and phenotype of homozygous?
Are you talking about phenotype or genotype? Phenotype is the expression of the genotype. Genotype is what you inherited. Phenotype is what you see. Homozygous is the same. Heterozygous is different. If you inherit one allele for blue eyes and one allele for brown eyes, your phenotype should be brown eyes. Your genotype would be brown eyes, blue eyes. You would have a heterozygous genotype.
When crossing a Rr genotype with a rr genotype what will the ratio of RR to rr be in the resulting generation?
50%Rr to 50%rr
What is geneotype?
Genotype versus Phenotype Genotype is your specific gene for a certain Trait. lets say B was for Tall gene and b is for small gene. your Genotype to Tall could be BB or Bb your gentype for small will be bb. Phenotype is what is the physical Appearance evne though the Genotpe has one gene that codes for big and one that codes for small for example (Bb) the physical appearnce is Tall.
What is the phenotype ratio of a cross between a heterozygous male and female?
The phenotypic ratio is a 3:1 ratio.
To determine the genotype of an individual that shows the dominant phenotype you would cross that individual with one that is?
To determine the genotype of an individual that shows the dominant phenotype you would cross that individual with one that is homozygous recessive. A monohybrid cross of two individuals that are heterozygous for a trait exhibiting complete dominance would probably result in a phenotype ratio is 3 dominant 1 recessive.
What kind of phenotype ratio would you expect from a mono-hybrid cross?
possible mendelian ratios for monohybrid cross genotype is 1:2:1 and phenotype is 3:1
What is the purpose of the punnett square?
Finding the genotype ratio for a cross.(Apex)
What a ratio?
A genotypic -ratio reflects the genetic configuration of an individual in the population. Several genotypes are possible in a phenotype and the ratio in which the genotypes segregate in a given phenotype is known as its genotypic ratio.
The unknown genotype of an individual with a dominant phenotype can be determined using?
This question is worded weird, because if someone had a dominant phenotype, as in Brown eyes dominant, than they would be BB or Bb. The exact genotype would need to have a key to what one of their parents' genotype was. Example: If a man with brown eyes (dominant) had a mom with blue eyes (recessive) then what would the man's genotype be? the answer would be Bb because that means that the man's dad would have BB and mom would be bb and when using punnent square, his genotype is Bb (only possible genotype is Bb)
What is used to show the results of any cross for a trait?
its either shown by Punet chart its like a checker box on sides of which gametes are wirten and inside the boxes the result of cross have to wirte the final results should be mentioned in the ratio either of phenotype or the ratio of offsprings in their genotype
