What are dominant alleles represented in the genotype AaBb?
There are four possible combinations of gametes for the AaBb parent. Half of the gametes get a dominant A and a dominant B allele; the other half of the gametes get a recessive a and a recessive b allele. Both parents produce 25% each of AB, Ab, aB, and ab.
What would the genotype BB be described as?
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. Finally, the genotype of an organism with two recessive alleles is called homozygous recessive.
What does an organism’s genotype describe?
In a broad sense, the term genotype refers to the genetic makeup of an organism; in other words, it describes an organism’s complete set of genes. A particular genotype is described as homozygous if it features two identical alleles and as heterozygous if the two alleles differ.
Which of the following genotypes are homozygous?
The correct answer: The genotype which shows the character of homozygous dominant is D.SS
Is AaBb dominant or recessive?
For example, the genotypes of AaBb, AaBB, AABb, and AABB are all different from each other, yet will all produce the same phenotype. Any individuals with any of these genotypes will exhibit dominant traits for both traits under consideration.
How many alleles are there in AaBb?
A heterozygous for two genes AaBb has two types of alleles for each gene: A and a, B and b.
What color is a person with AaBb genotype?

Is AaBb a phenotype?
There are only three different phenotypes for hair color, agouti, black and albino. The individual with genotype recessive for both traits, i.e. aabb, has the same albino phenotype as the aaBB and aaBb individuals due to epistasis.
