In fruit flies, long-wing (L) is dominant to vestigial (l). Two long-wing flies produce 49 vestigial and 148 long-wing offspring.

What are the probable genotypes of the parents?

What proportion of the long-wing offspring should be heterozygous?

A student carried out a genetic investigation with fruit flies, Drosophila melanogaster. Two characteristics were observed, body colour and wing shape. The student had the followinginformation: the characteristics were controlled by separate genes carried on separate chromosomes grey body colour was dominant to black body colour normal wing shape was dominant to bent wing shape. The student carried out a cross between a fly heterozygous for both grey body colour and normal wing shape and a fly with a black...

Red eyes and curly wings are dominant traits in the fruit flies. True-breeding flies with red eyes and curly wings were crossed to true-breeding flies with white eyes and vestigial wings. The F1 generation flies, which had red eyes and curly wings, were mated to each other. What is the probability of obtaining the following seven flies in the F2 generation: four that have red eyes and vestigial wings; one with red eyes and curly wings, and two with white...

You are doing a genetics experiment with fruit flies. In your first cross, you cross two true-breeding flies (P generation). The female parent is brown and wingless and the male parent is black with normal wings. All of the flies in the F1 generation are brown and have normal wings. In the following questions, please indicate the alleles associated with dominant phenotypes by uppercase letters and alleles associated with recessive phenotypes by lowercase letters. Assume the genes are not found...
