11 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 Show work here
