What is the genotype of RR?
The (RR) genotype is homozygous dominant and the (rr) genotype is homozygous recessive for seed shape. In the image above, a monohybrid cross is performed between plants that are heterozygous for round seed shape. The predicted inheritance pattern of the offspring results in a 1:2:1 ratio of the genotype.
What is genotype BB?
An organism with two dominant alleles for a trait is said to have a homozygous dominant genotype. Using the eye color example, this genotype is written BB. An organism with one dominant allele and one recessive allele is said to have a heterozygous genotype. In our example, this genotype is written Bb.
What genotype is yy?
Yy is the heterozygous genotype (one dominant allele, one recessive allele). The phenotype of this genotype is yellow seed color.
What is the genotype of an individual?
A genotype is an individual’s collection of genes. The term also can refer to the two alleles inherited for a particular gene. The expression of the genotype contributes to the individual’s observable traits, called the phenotype.
What are some examples of a genotype?
Other examples of genotype include: Hair color. Height. Shoe size….Genotype examples
- A gene encodes eye color.
- In this example, the allele is either brown, or blue, with one inherited from the mother, and the other inherited from the father.
- The brown allele is dominant (B), and the blue allele is recessive (b).
What is AA and AS genotype?
If the dominant allele is labeled as “A” and the recessive allele, “a”, three different genotypes are possible: “AA”, “aa”, and “Aa”. The term “homozygous” is used to describe the pairs “AA” and “aa” because the alleles in the pair are the same, i.e. both dominant or both recessive.
What are the six genotypes?
A description of the pair of alleles in our DNA is called the genotype. Since there are three different alleles, there are a total of six different genotypes at the human ABO genetic locus. The different possible genotypes are AA, AO, BB, BO, AB, and OO.
What genotype is FF?
Mendelian Genetics
| Genotype | Phenotype | |
|---|---|---|
| F F | Homozygous dominant | No cystic fibrosis (Normal) |
| F f | Heterozygous | Carrier (has no symptoms but carries the recessive allele) |
| f f | Homozygous recessive | Cystic fibrosis (has symptoms) |
The result in the heterozygous genotype (Rr) is a phenotype that is a mixture of red and white, or pink. Furthermore, what is the genotype of RR? A homozygous plant contains either of the following alleles for seed shape: (RR) or (rr).
What is the genotype of a homozygous plant?
A homozygous plant contains either of the following alleles for seed shape: (RR) or (rr). The (RR) genotype is homozygous dominant and the (rr) genotype is homozygous recessive for seed shape. In the image above, a monohybrid cross is performed between plants that are heterozygous for round seed shape.
What is the heterozygous genotype for Red?
The allele that produces red flower color (R) is not completely expressed over the allele that produces white flower color (r). The result in the heterozygous genotype (Rr) is a phenotype that is a mixture of red and white, or pink. What does homozygous mean in biology?
What is an example of a genotype in biology?
For example, a test cross between two organisms with same genotype, Rr, for a heterozygous dominant trait will result in offspring with genotypes: RR, Rr, and rr. And in this example, the predicted genotypic ratio is 1:2:1. What does phenotype mean in biology?
