Detailed explanation-1: -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.

Detailed explanation-2: -Individuals inherit two versions of each gene, known as alleles, from each parent. In the case of a recessive trait, the alleles of the trait-causing gene are the same, and both (recessive) alleles must be present to express the trait. A recessive allele does not produce a trait at all when only one copy is present.
