3. explain why knowing one is a carrier of a
recessive trait is important.

Because if they mate with another carrier of the recessive trait, then the offspring is at risk of having the trait.

Explanation:

I determines what trait they have of the father or the mother, usually fathers have recessive traits. I am a recessive traits because I look like all of my dad's sisters instead of my own mom, I have my mothers nose and that is it.

Explanation:

When a trait is recessive, an individual must have two copies of a recessive allele to express the trait. Recessive alleles are denoted by a lowercase letter (a versus A). Only individuals with an aa genotype will express a recessive trait; therefore, offspring must receive one recessive allele from each parent to exhibit a recessive trait.

One example of a recessive inherited trait is a smooth chin, as opposed to a dominant cleft chin. Let (S) represent the dominant allele, and (s) represent the recessive allele. Only (ss) individuals will express a smooth chin. To determine the probability of inheritance of a smooth chin (or any other recessive trait), the genotypes of the parents must be considered. If one parent is heterozygous (Ss) and the other is homozygous recessive (ss), then half of their offspring will have a smooth chin.
