Drosophila fruit flies are diploids (2n=2x=8). 4. How many total chromosomes would a monosomic diploid fly ( 2n1) have in a somatic cell: A. 6 B.7C.8 D. 9 E. 12 F. 14 G. 18 5. Suppose a monosomic chromosome IV female Drosophila fly that has white eyes (a recessive X-linked trait) and normal bristles is crossed with a male with a diploid set of chromosomes and normal red eye color but homozygous for the recessive chromosome IV bristle mutation shaven (sv). In the F1 generation, what is the expected proportion of white-eyed, shaven-bristled progeny? A. 1/16 C. 1/2 E. 3/16 G. 1 B. 1/4 D. 3/4 F. 9/16 H. 0.
