Q. Select the statement which is not correct.
A) Polygenic character is controlled by multiple alleles
B) In case of polygenic inheritance, thousands of intermediate phenotypes are found between two extreme ones
C) Height, weight, skin colour are polygenic
D) ABO blood group system is an example of multiple allelism
Explanation
Genes at more than one locus are called as polygenes. Variation in these genes in a particular population have a combined effect upon a particular phenotypic character. Multiple alleles are the more than two different forms of a gene, present on the same locus.
