A scientist named Thomas Hunt Morgan studied genetics in fruit flies. Specifically he looked at wild type (normal) wings versus vestigial (shortened) wings. When he crossed a wild type female with a vestigial male he expected to see 50% parental phenotypes and 50% recombinant phenotypes in the offspring. However, what he actually found was 83% parental phenotypes and 17% recombinant phenotypes. What does this suggest about the genes he was studying? How do the percentages help us determine this?

More offspring resembles to parents.

Explanation:

The percentages help us to determine that the parental genes are dominant in the offspring and more percentage of offspring resembles to the parents whereas low percentage of offspring are hybrid in nature. Hybrid means the offspring which are different from their parents or having new characteristics. So the results shows that 83% offspring resembles to their parents whereas 17% offspring are totally different from the parents.

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.
