Monohybrid cross with incomplete dominance

Vedclass · Answer

(D) In a standard Mendelian monohybrid cross with complete dominance,the phenotypic ratio is $3:1$ and the genotypic ratio is $1:2:1$.However,in cases of incomplete dominance (e.g.,in $Antirrhinum$ $majus$ or snapdragon),the dominant allele does not completely mask the recessive allele.As a result,the heterozygotes show an intermediate phenotype.Therefore,in the $F_2$ generation of an incomplete dominance cross,the phenotypic ratio becomes $1:2:1$ ($1$ red : $2$ pink : $1$ white),which is identical to the genotypic ratio $(1:2:1)$.

In a Mendelian cross,the $F_2$ generation shows that both the genotypic ratio and the phenotypic ratio are the same,i.e.,$1:2:1$. This indicates:
