Let us suppose that two long-winged flies were crossed and that 77 long-winged and 24 short-winged specimens were counted in the offspring. a. Will the short-winged character be dominant or recessive?B. What will the genotypes of the parents be?C. What is the observed genotype ratio?
In a test cross, an individual dominant for a certain trait ( whether homozygous or heterozygous is unknown) is crossed with a homozygous recessive individual. A plant with spherical seeds is crossed with another plant. If the genotypes and phenotypes of the offspring are 100% heterozygous and 100% dominant, what were the genotypes of the parents? (hint: try multiple crosses until you find what works) If the genotypes and phenotypes of the offspring are 50% heterozygous spherical seeds and 50% wrinkled seeds, what were the genotypes of the parents?
Bateson and Punnett crossed two white-flowered lines and saw all purple flowers in the F1 generation.

A) 8 purple to 8 white B) 16 purple to 0 white C) 0 purple to 16 white D) 7 purple to 9 white E) 9 purple to 7 white

(c) Two different matings were made between black members of the F2 generation, with the following results. Cross Offspring Cross 1 All black Cross 2 3/4 black, 1/4 white Diagram each of the crosses.
