पर्याय

• 4 genotypes

• 3 genotypes

• 2 genotypes

• 1 genotype

Answer 1

Wrinkled yellow seeds in the F₂ generation result from the homozygous recessive rr genotype (wrinkled) combined with at least one Y allele (yellow). The 2 genotypes that produce this phenotype are: rrYY and rrYy, representing the 3 out of 16 combinations in the 9:3:3:1 phenotypic ratio.
