Detailed explanation-1: -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.

Detailed explanation-2: –The physical expression of a trait is called the phenotype.-A dominant trait will mask the expression of a recessive trait. For example, in this section a genotype of Ff (one dominant and one recessive allele) will express a freckled phenotype. Freckles are a dominant trait.

Detailed explanation-3: -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.

Detailed explanation-4: -Freckles are recessive and no freckles are dominant. Mom is heterozygous dominant (Ff) and dad is homozygous recessive (ff).
