Dominance

Vedclass · Answer

(A) In pea plants,the gene $B$ controls starch synthesis and seed shape. $BB$ homozygotes produce large starch grains and round seeds. $bb$ homozygotes produce small starch grains and wrinkled seeds. In the heterozygous condition $(Bb)$,the starch grains are of intermediate size,which suggests incomplete dominance for starch grain size. However,the phenotype of the seed shape in $Bb$ individuals is round,which is identical to the $BB$ phenotype. Therefore,with respect to the seed shape,the $B$ allele shows complete dominance over the $b$ allele.

In pea plants,if the $Bb$ gene is present in a heterozygous condition for starch grain synthesis,what type of inheritance does the round seed shape exhibit?
