Q. In Drosophila melanogaster, what percentage of recombination is shown between the genes white and yellow, and what percentage of linkage is shown between the genes white and miniature wing, respectively?

Solution:

In Drosophila melanogaster, genes for white and yellow colour are about $1.3$ map unit distant from each other so they show 1.3 % recombinations while 98.7% linkage (or parental characters). Genes for white colour and miniature wing are about 37.2 map unit distant so they show 37.2% recombinations and 62.8% linkage (or parental characters).
