In Drosophila, Singed Bristles (Sn)and Carnation Eyes (Car)are Both Caused

Question 72

Multiple Choice

In Drosophila, singed bristles (sn) and carnation eyes (car) are both caused by recessive X-linked alleles.The wild-type alleles (sn+ and car+) are responsible for straight bristles and red eyes, respectively.A sn car female is mated to a sn+ car+ male and the F1 progeny are interbred.The F2 are distributed as follows:
