Answer to Question #64130 in Genetics for afsana hossain

Question

a new student of genetics suspects that a particular recessive trait in fruit flies (dumpy wings: d) is sex linked. A single mating between a female fly having dumpy wings and a male fly with normal wings (D) produces 3 dumpy- winged females and 2 normal males. On the basis of these data, is the trait sex-linked or autosomal? what were the genotypes of the parents? explain how the conclusions can be reached on the basis of so few data. male fruit flies are XY and females are XX.
