![Lets consider two genes A and B linked at 5 CM. The recessive mutant alleles "a" and "b" are
responsible for the mutant phenotypes [a] and [b] respectively. Two parents of pure strains but of
unknown genotypes and phenotypes are crossed. The F1 is homogeneous with a [wild type]
phenotype. The progeny of the test-cross on F1 individuals gives: 2.7% [a, b], 46.8% [a], 47.2% [b]
and 3.3% [wild type]. This distribution shows that (tick the correct statements):
genes A and B are dominant
no correct answer
the distance between A and B is about 6 cM
genes A and B are linked
the alleles are in cis position
genes A and B are epistatic
the distance between A and B is about 3 cM
the distance between A and B is about 44 CM
