Question

There are two alleles for the height gene, T for tall and t for short. One parent is a heterozygote, while the other is a recessive homozygotes. Which genotypes, and at which frequencies, are possible from these two parents. a.) 100% heterozygotes b.) 100% dominant homozygotes c.) 50% dominant homozygotes, 50% recessive homozygotes d.) 50% dominant homozygotes, 50% heterozygotes e.) 50% heterozygotes, 50% recessive homozygotes f.) 25% dominant homozygotes, 50% heterozygotes, 25% recessive homozygotes g.) 100% recessive homozygotes

Expert Solution

Step 1: Explaining homozygous dominant, recessive and heterozygous condition

A genotype is represented by two alleles which are alternative form of genes. These two alleles can be either homozygous dominant or homozygous recessive or heterozygous. Heterozygous are always dominant as in this case it contains one dominant and one recessive allele and dominant allele takes over the phenotype of recessjve allele.
