Incomplete dominance

Vedclass · Answer

(B) In pea plants, the gene for starch synthesis has two alleles, $B$ and $b$. $BB$ homozygotes produce large starch grains, while $bb$ homozygotes produce small starch grains. However, the $Bb$ heterozygotes produce intermediate-sized starch grains. Since the phenotype of the heterozygote is intermediate between the two homozygous phenotypes, this is an example of $Incomplete 	ext{ } dominance$.

The presence of the $Bb$ gene in pea plants results in intermediate-sized starch grains. Which phenomenon does this represent?
