It is heterozygous.
Heterozygous means that one allele is dominant and the other is recessive, Rr

What type of alleles are presented in a homozygous genotype?
homozygous(different gene)-Rr heterozygous(same gene)-RR,rr
If R is dominant to r the offspring of the cross of RR with rr will be homozygous?
R R r Rr Rr r Rr Rr That is the Punnet Square. The genotype will be 100% Rr in the cross. The phenotype will be whatever phenotype is constituted by your dominant allele.
O neg and O pos parents what happens to children?
The genotype for Rh positive blood is either RR or Rr and the genotype for Rh negative blood is rr. Since the child gets one gene from each parent, they have the possibility of being either.
What is recessive gene and dominant gene?
A dominant gene is always expressed if present, and the recessive gene is only expressed with the homozygous recessive genotype. For example, if the dominant gene is red (represented by the letter R) and the recessive gene is white (represented by the letter r), then a homozygous dominant organism's genotype will be RR, and its phenotype will be red. If the organism is homozygous recessive, then the genotype will be rr and the phenotype will be white. If the organism is heterozygous, then the genotype will be Rr, and the organism will be red.
In a certain plant rough seeds R are dominant and smooth seeds r RECESSIVE two plants with genotype?
rr
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 genotype of a carrier?
Rr heterozygous
What is dominant recessive?
There is dominant and there is recessive. There is no dominant recessive. A dominant gene will always be expressed when present, such as in the homozygous dominant genotype (RR), or heterozygous genotype (Rr). A recessive allele is only expressed when the genotype is homozygous recessive (rr).

If R is dominant to r the offspring of the cross of RR with rr will be homozygous?
R R r Rr Rr r Rr Rr That is the Punnet Square. The genotype will be 100% Rr in the cross. The phenotype will be whatever phenotype is constituted by your dominant allele.
What is the genotype of a red flower crossed with a blue flower?
It Depends If The Red Flower Is Dominant then it should Be RR but if its Recessive then its rr so depending on the F1 you should know the Genotype of The Red FLower.
O neg and O pos parents what happens to children?
The genotype for Rh positive blood is either RR or Rr and the genotype for Rh negative blood is rr. Since the child gets one gene from each parent, they have the possibility of being either.
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
What is the genotype for sickle cell anemia?
homozygous recessive (rr) & Heterozygous (Rr) homozygous recessive (rr) & Heterozygous (Rr)
What is recessive gene and dominant gene?
A dominant gene is always expressed if present, and the recessive gene is only expressed with the homozygous recessive genotype. For example, if the dominant gene is red (represented by the letter R) and the recessive gene is white (represented by the letter r), then a homozygous dominant organism's genotype will be RR, and its phenotype will be red. If the organism is homozygous recessive, then the genotype will be rr and the phenotype will be white. If the organism is heterozygous, then the genotype will be Rr, and the organism will be red.
In a certain plant rough seeds R are dominant and smooth seeds r RECESSIVE two plants with genotype?
rr
Use a punnet square to predict the results of a monohybrid cross starting with the phenotypic and genotypic r?
A punnet square is a 2x2 grid that is used to show the probability of an offspring showing a certain genotype and phenotype. The genotype is shown by using a letter for the trait. A capital letter is used to represent a dominant allele and a lowercase letter is a recessive. Ie: a heterozygous individual would be shown as having genotype Rr for a trait. If their genotype contains at least one dominant allele, then their phenotype is shown as the dominant trait. If the trait is eye color, R being dominant brown eyes, and r being recessive blue eyes, then the individual with either RR or Rr will have brown eyes. and if they have rr, then they have blue eyes. Now back to the punnet square, The top of the square will have the genotype of one parent, and the side will have another parent. If the father is RR, then each column will have a R over it. If they are Rr, then the first column will have an R and the second will have a r. Likewise, if they are recessive, then the top of the square will have rr. The same is shown on the rows on the side. The genotype goes down the two squares on the side. The genotype probability is found by crossing each allele in the boxes. If one box has R over it, and r to the right, then the box contains Rr. This is used to fill in all four boxes. In the end, If you have {RR, Rr, rr, rr} as your resulting genotypes, then there is a 50% chance that the offspring will have Dominant or recessive phenotype. The genotype ratio is then 1:2:1 and the phenotypic ratio is 2:2.
