Question

During incomplete dominance, $F_{2}-$ generation will have

• A. $3:1$ genotypic ratio
• B. $3:1$ phenotypic ratio
• C. $1:2:1$ genotypic ratio
• D. $1:2:1$ phenotypic ratio

Answer 1

Answer: (D)

$1:2:1$ phenotypic ratio

Answer 2

Incomplete dominance the genes of an allelomorphic pair are not expressed as recessive and dominant and is expressed themselves partially, e.g., plant like Antirrhinum, when the hybrid of $F_1$, progeny are crossed among themselves to raise $F_{2}-$ generation, they produce a phenotypic ratio of $1:2:1,$ which is identical to genotypic ratio because heterogygote are phenotypically intermediate between homozygous types,
