Let's suppose that three genes affecting eye color, body color, and wing length are on the same chromosome in fruit flies. In a test cross, if the number of recombinant offspring involving eye color and wing length is much higher compared to body color and eye color, these results suggest that:.

The genes of eye color and wing length are present far from each other than the genes of body color and eye color.

Explanation:

Recombination requires the presence of genes far apart from each other on the same chromosome. When two genes are present close to each other, they are less likely to undergo the process of crossing over. This results in the formation of a higher proportion of progeny of parental types. On the other hand, when genes are far apart, a higher number of recombinant progeny is formed due to more chances of crossing over.

A higher number of recombinant offspring involving eye color and wing length compared to the body color and eye color suggests that the distance between the genes of eye color and wing length is greater than that of body color and eye color.

i have to report this, it doesn't relate to biology
