Explanation:
Detailed explanation-1: -When a trait is dominant, only one allele is required for the trait to be observed. A dominant allele will mask a recessive allele, if present. 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.
Detailed explanation-2: -The term “recessive” describes a trait that is covered over (or dominated) by another form of that trait and seems to disappear.
Detailed explanation-3: -autosomal dominant – where the gene for a trait or condition is dominant, and is on a non-sex chromosome. autosomal recessive – where the gene for a trait or condition is recessive, and is on a non-sex chromosome.
