how is polygenic inheritance and multiple allelism different? explain wid an eg
Answers
Polygenic inheritance: It is the inheritance of a characteristic that is controlled by more than one gene. Polygenic inheritance can produce unexpected phenotypes.Phenotypes that don't fit with Mendel's expected outcomes based on independent assoectment of dominant and recessive alleles.Two examples of Polygenic inheritance are: 1 Skin colour in humans 2. Height in humans Multiple allelism: In this more than one alleles governs the same character and phenotype. Example: Human blood group (ABO system) controlled by three alleles (IA, IB and i).
