Incomplete dominance

Vedclass · Answer

(D) In a typical Mendelian monohybrid cross,the phenotypic ratio is $3:1$. However,in cases of incomplete dominance,the dominant allele does not completely mask the recessive allele. As a result,the heterozygote $(Aa)$ exhibits an intermediate phenotype between the dominant and recessive traits. Therefore,the $F_2$ generation shows a phenotypic ratio of $1$ (homozygous dominant) : $2$ (heterozygous intermediate) : $1$ (homozygous recessive),which matches the genotypic ratio.

In the $F_2$ generation of a monohybrid cross,the cause of the $1:2:1$ phenotypic ratio is:
