(B) The inheritance of starch grain size in pea plants is an example of incomplete dominance.Let $B$ represent the allele for large starch grains and $b$ represent the allele for small starch grains.The genotype $BB$ produces large starch grains,$bb$ produces small starch grains,and the heterozygous genotype $Bb$ produces intermediate sized starch grains.When both parents are heterozygous $(Bb 	imes Bb)$,the phenotypic ratio of the progeny is $1:2:1$ $(BB:Bb:bb)$.Here,$25\%$ of the progeny will be $BB$ (large),$50\%$ will be $Bb$ (intermediate),and $25\%$ will be $bb$ (small).Therefore,$50\%$ of the progeny will have intermediate sized starch grains.

In a cross between male and female pea plants,both are heterozygous for round seeds,what percentage of the progeny will be having intermediate sized starch grains (in $\%$)?
