You cross a true breeding pea comb chicken with a single comb chicken. What will you observe in the F2 generation?
ExplanationPea comb has genotype P/P r/r and single has genotype p/p r/r. Thus the cross will give F1 P/p r/r. This is homozygous recessive at R locus so F2 will only differ in P locus giving monohybrid ratio 3:1.
