Options:

Answer:
C
Solution:

In Drosophila melanogaster, genes for white and yellow colour are about1.3map 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).
