Question

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 2 extreme ones
• C. Height, weight, skin colour are polygenic
• D. Polygenic character is controlled by multiple genes

Answer 1

Answer: (A)

Polygenic character is controlled by multiple alleles

Answer 2

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.
