Suppose that out of 1000 offspring’s in the generation of a dithered cross, 748 are tall and hairy, 6 are tall and smooth, 4 are short and hairy and 242 are short and smooth. what is the explanation for this kind of ratio ?

Question

Accepted Answer

Linkage and crossing over. The ratio deviates from the expected 9:3:3:1 Mendelian dihybrid ratio, indicating gene linkage. The presence of recombinant phenotypes (tall/smooth and short/hairy) confirms crossing over occurred between linked genes.
