1.A female drophilia fly heterozygous for the traits sh and be was mated to a heterozygous male with sh and be. both taits are recessive. 800 progeny were scored with the phenotypes: wild type head, wildtype eyea 380 sh, wildtype eyea 35 sh, be. 340 wild type head, big eyes 45 A.what do these results tell about. sh and be genes? B.identify the recombinant phenotypes in progeny C.estimate then map distance between the two genes. show calculations.
2.An achondroplastic male dwarf with normal vision marries a color-blind woman of normal height. The man's father was six-feet tall, and both the woman's parents were of average height. Achondroplastic dwarfism is autosomal dominant, and red-green color blindness is X-linked recessive.
What are the genotypes of:
The male dwarf:
His wife:
How many of their daughters might be expected to be color-blind dwarfs?
How many of their sons would be color-blind and of normal height?
