ANSWER:-
MULTIPLE ALLELES:-
☘ Alleles are alternative forms of a gene.
☘ More than two alleles if s gene are called multiple alleles and the phenomenon is called multiple allelesome.
☘ They are responsible for differences in phenotypic expression of a given trait.
☘ Multiple alleles of a gene are present at the same locus on homologous chromosomes.
☘ A, B, O blood grouping is an excellent example.
☘ It was discovered by Karl Landsteiner.
☘ The inheritance of multiple alleles was explained by Bern Steiner.
☘ Lansteiner discovered two antigens namely Antigen A and Antigen B.
☘ Based on the presence of Antigen A and Antigen B, he classified four types of blood groups.
☘ Most genes are not multiple alleles but they exists only in one or two forms within a population.
