Answer:
Explanation:
Recessive Trait Definition A recessive trait is a trait that is expressed when an organism has two recessive alleles, or forms of a gene. Traits are characteristics of organisms that can be observed; this includes physical characteristics.
In general, recessive alleles show up in your phenotype only if you have two of them. Even though you have only two alleles per type of gene, many traits can be expressed in more than two ways. For example, your hair might be any one of several colors.
Recessive Inheritance - Genetics Generation Recessive Inheritance 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).
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.
