Vedclass · Answer

(A) In a monohybrid cross,Mendel observed that the $F_1$ generation expressed only one of the parental traits (dominant). When $F_1$ hybrids were self-pollinated,the $F_2$ generation showed both parental traits in a phenotypic ratio of $3:1$. This $3:1$ ratio is a direct result of the law of dominance,where the dominant allele masks the expression of the recessive allele in the heterozygous condition. Therefore,this phenomenon is explained by complete dominance.

In the case of inheritance of one gene,the phenotypic ratio of $3:1$ can be explained on the basis of which of the following?
