Which of the following is NOT true of a genotype like AA
|
|
it shows the 2 alleles inherited by an offspring.
|
|
|
Each letter represents the form of a trait inherited from one of the parents.
|
|
|
Each letter represents an allele from one of the parents.
|
|
|
Each letter represents a recessive form of a trait
|
Explanation:
Detailed explanation-1: -A dominant allele is denoted by a capital letter (A versus a). Since each parent provides one allele, the possible combinations are: AA, Aa, and aa. Offspring whose genotype is either AA or Aa will have the dominant trait expressed phenotypically, while aa individuals express the recessive trait.
Detailed explanation-2: -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.
