NEET BIOLOGY

Detailed explanation-1: -Polygenics. A person who is a heterozygous for albinism is called a. Carrier. An intermediate heterozygous phenotype between two homozygous Phenotypes is called. Incomplete dominance.

Detailed explanation-2: -Humans have two versions of all autosomal genes, called alleles, one from each parent. The recessive trait is hidden in the heterozygous individual (Dd) if the other allele is inherited in a dominant fashion, and so this person is a called a “carrier” of the recessive allele, but does not manifest the disease or trait.

Detailed explanation-3: -A person with one abnormal gene is called heterozygous for that gene. If a child receives an abnormal recessive disease gene from both parents, the child will show the disease and will be homozygous (or compound heterozygous) for that gene. GENETIC DISORDERS. Almost all diseases have a genetic component.

Detailed explanation-4: -The parents of a child with an autosomal recessive condition usually do not have the condition. Unaffected parents are called carriers because they each carry one copy of the mutated gene and can pass it to their children.

Detailed explanation-5: -Heterozygous, as related to genetics, refers to having inherited different versions (alleles) of a genomic marker from each biological parent. Thus, an individual who is heterozygous for a genomic marker has two different versions of that marker.
