Polygenic inheritance refers to the inheritance of a trait governed by more than one gene. In a polygenic trait the phenotype reflects the contribution of each allele i.e., the effect of each allele is additive. Hence, statement I is incorrect and statement II is correct.
Given below are two statements: Statement I: When many alleles of a single gene govern a character, it is called polygenic inheritance. Statement II:…
