Drosophila have X and Y chromosomes and determine sex in a manner that is similar to mammals. (That is, XX is female and X Y male.) Little fly (Iff) and carnation eye (car) are recessive alleles of the X chromosome. A cross is made between a little, carnation female and a homozygous wild-type male, yielding all wild-type females and all little, carnation males for F 1 . The F 1 flies are then bred together, yielding the following F 2 . Assume that each phenotype is 50% male, 50% female. a. Diagram the cross. (1 poin b. Determine the NCO and SCO offspring and calculate the distance (in mu) between car and If. (1 poin .
