Imagine you have a VERY large garden consisting of thousands of red-flowered individuals (recessive homozygotes rr) and just a few dozen white-flowered plants (genotypes either RR or Rr) of the same species. The garden is isolated from all other flower populations. What do you think will happen to the frequency of the white-flowered plants in your garden from year to year, assuming that the two phenotypes survive and reproduce equally well, that flower color is inherited as a dominant trait, and that pollinating insects make no distinction in flower color? Why?

In tomatoes, one gene determines whether the plant has purple (P) or green (G) stems, and a separate, independent gene determines whether the leaves are “cut” (C) or “potato” (Po). Five matings of tomato-plant phenotypes give the following results: Parental Number of progeny Mating phenotypes P, C P, Po G, C G, Po 1 P, C × G, C 323 102 309 106 2 P, C × P, Po 220 206 65 72 3 P, C × G, C 723 229 0 0 4 P, C × G, Po 405 0 389 0 5 P, Po × G, C 71 90 85 78 a. Which alleles are dominant? b. What are the most probable genotypes for the parents in each cross?

In fruit flies, you are studying three genes, whose recessive alleles can generate interesting traits. The abnormal traits are “short” – gene s, “ruby-eyed” – gene r, and “ebony body” – gene e. You have been provided an F1 population of flies that are heterozygous at all three of these gene and you testcross these flies by “ssrree” flies. The attached image lists any recessive traits displayed by the flies, unlisted traits are wild type. a) the genotype of the parental flies used to make the F1 population,b) determine if any of these three genes are located on the same chromosome or are unlinked,c) if possible, correct your data for double crossover events evidenced in the ratios,

In fruit flies, long wings (L) are dominant over short wings (l). In a population of 45 fruit flies, 27 have LL genotypes, 13 have Ll genotypes,  and 5 have ll genotypes. Find the frequency of the following. Show all work and record your answer as a value between 0 and 1 rounded to two decimal places.a. long-winged fruit flies: b. short-winged fruit flies:
