Detailed explanation-1: -With eye color, for instance, “B” stands for a brown allele and “b” stands for a blue allele. 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.
Detailed explanation-2: -Answer and Explanation: The two gametes produced by the individual with the genotype Bb will be B and b, as shown in the picture below.
Detailed explanation-3: -The different types of genotypes are-homozygous recessive (pp), homozygous dominant (PP), and heterozygous (Pp).
Detailed explanation-4: -Individuals with genotypes AA and aa are homozygotes (i.e., they have two copies of the same allele). Individuals with genotype Aa are heterozygotes (i.e., they have two different alleles at the A locus).
