NEET BIOLOGY

Detailed explanation-1: -The A, B, AB and O blood group types in humans are determined by three alleles of a gene. The gene I, which determines the blood type, exists in three allelic forms, which are IA, IB and i.

Detailed explanation-2: -An excellent example of multiple allele inheritance is human blood type. Blood type exists as four possible phenotypes: A, B, AB, & O. There are 3 alleles for the gene that determines blood type.

Detailed explanation-3: -Blood type in humans is normally controlled by multiple alleles but not multiple genes. Human blood type or ABO blood type is controlled by the ABO gene, which has three distinct alleles (multiple alleles), a, b, and I.

Detailed explanation-4: -Although humans (and all diploid organisms) can have only two alleles for any given gene in genetics, multiple allele traits may exist at the population level. Thus, multiple alleles are important in promoting variation within the same species.

Detailed explanation-5: -One example of a trait the has multiple alleles is the human ABO blood group trait. There are three different alleles-allele A, allele B and allele i. If the chromosome contains the allele A, then protein A is created and the red blood cells of that particular individual will contain protein A on their membrane.
