AP BIOLOGY

Detailed explanation-1: -The only possible genotype for flashy feathers is ff (homozygous recessive). The possible genotypes for normal feathers are FF (homozygous dominant) and Ff (heterozygous).

Detailed explanation-2: -An example of a homozygous recessive genotype would be tt, where the lower case t’s represent the recessive trait. Homozygous means the same and genotype means the gene type.

Detailed explanation-3: -Freckles are recessive and no freckles are dominant. Mom is heterozygous dominant (Ff) and dad is homozygous recessive (ff).

Detailed explanation-4: -Your Alpha-1 genotype is FF. This means that you have two copies of the F mutation in your Alpha-1 genes. This is a rare form of alpha-1 antitrypsin deficiency.
