You breed two monster parents (green, hairless) GGhh and ggHH (white, hairy) to produce F1 offspring (green, hairy). Genes G and H are on the same chromosome. a. What are the dominant phenotypes? b. What are ALL of the potential gamete genotypes that could be created by an F1? Clearly indicate the recombinant genotypes. c. Explain how recombinants are created. d. What are the potential offspring genotypes from the cross of a F1 monster with a homozygous recessive monster. e. From this test cross you get 152 green, hairless; 23 green, hairy; 148 white, hairy, and 27 white, hairless. Calculate the chi squared to test the independent assortment hypothesis and determine if these genes assort independently.

How would one explain a testcross involving F1 dihybrid flies in which more parental-type offspring than recombinant-type offspring are produced? Group of answer choices A. The testcross was improperly performed B. The two genes are linked C. Both of the characters are controlled by more than one gene D. The two genes are linked but on different chromosomes E. Recombination did not occur in the cell during meiosis

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?
