answer
2-Female Drosophila heterozygous for three recessive mutations e
(ebony body), st (scarlet eyes), and ss (spineless bristles) were
testcrossed, and the following progeny were obtained: Phenotype
Number wild-type 134 ebony 16 ebony, scarlet 136 ebony, spineless
694 ebony, scarlet, spineless 156 scarlet 736 scarlet, spineless 20
spineless 108 (a) What indicates that the genes are linked? 1 mark
(b) What was the genotype of the original heterozygous females? 1
mark (c) What is the order of the genes? 1 mark (d) What is the map
distance between e and st? 1 mark (e) Between e and ss? 1 mark? 1
mark (f) What is the coefficient of coincidence? 1 mark (g)
Calculate the interference? 1 mark (h) Diagram the crosses in this
experiment. 1 mark
