Complete dominance

Vedclass · Answer

(A) In pea plants,the gene for starch synthesis has two alleles,$B$ and $b$. $BB$ homozygotes produce large starch grains and are round in shape. $bb$ homozygotes produce smaller starch grains and are wrinkled in shape. $Bb$ heterozygotes produce intermediate-sized starch grains and are round in shape. Since the phenotype of the heterozygote $(Bb)$ is similar to the dominant homozygote $(BB)$ in terms of seed shape,this is an example of complete dominance.

The synthesis of starch in pea seeds is controlled by a single gene. This gene has two alleles,$B$ and $b$. If the shape of the pea seed is considered as the phenotype,what type of inheritance does this represent?
