In a Mendelian monohybrid cross, the $F_2$ generation shows identical genotypic and phenotypic ratios. What does it tell us about the nature of alleles involved? Justify your answer.
In a monohybrid cross, starting with parents which homozygous dominant and homozygous recessive $F_{1}$, would be heterozygous for the trait and would express the dominant allele. But in case of incomplete dominance a monohybrid cross shows the result as follows.
Phenotypic ratio $\rightarrow$ Red : Pink: White :: $1: 2: 1$
Genotypic ratio $\rightarrow$ $RR$ : $Rr$: $rr$ : : $1: 2: 1$
Alleles can show incomplete Dominance when genotypic and phenotypic ratios are same.
In which cross will you get most pink flowers?
In poultry, new comb colour appears by colaboration of two dominant gene is
In Antirrhinum (Snapdragon), a red flower was crossed with a white flower and in $\mathrm{F}_{1}$ generation, pink flowers were obtained. When pink flowers were selfed, the $\mathrm{F}_{2}$ generation showed white, red and pink flowers.
