3. Choose and identify ONLY FOUR of the following reproductive isolating mechanism for theexamples below. Mechanisms can be used more than once.Type of ReproductiveIsolating MechanismExampleHybrid embryos between sheep and goats die in early development.Some fish that live in shallow water compared to fish that live indeep water.Cotton plants produce fertile hybrids, but their offspring do notsurvive.Flowers that bloom at different times in a season.Mules are the product of horses and donkeys but are sterile.Genital anatomy may vary enough that the species' parts do not fittogether.Differences in the mating calls of frogs.Pollen grains from one plant may not survive the conditions foundon the stigma of another plant.

2. In corn the genes for tassel length (alleles T and t) and rust resistance (alleles R and r) are known to be on separate chromosomes. In the course of a routine mating check experiment, a breeder got the following results upon crossing T/t:R/r with a double recessive strain (t/t/r): Number of progeny genotype T/t; R/r t/t; r/r T/t; r/r t/t; R/r In addition to these data she noted that the cobs contain only about 50% of the expected kernels. Note that in corn, each kernel is the result of one mating or can be considered one progeny. Hence 50% of the matings are not producing viable offspring. a. Based on the location of these genes on separate chromosomes what is the 98 104 3 5 expected result? b. Suggest a hypothesis of a genetic process that could be used to explain the potential karyotype of one of these parents. c. What are the actual genotypes of the parents? d. Draw a diagram (hand drawn diagrams are fine just scan the image and insert it into your exam as picture) showing the…
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,
Which of the following examples suggested to Charles Darwin that hybridization between different animal species was often of no reproductive benefit to the hybrid animals? crossing of a female European wildcat with a male housecat to produce fertile hybrids crossing of a male dog with a female gray wolf to produce fertile hybrids crossing of a female housecat with a male African wildcat to produce fertile hybrids crossing of a male donkey with a female horse to produce sterile hybrids crossing of a female gray wolf with a male coyote to produce fertile hybrids
A map distance of 23 between two genes indicates which of the following? the genes are 23 millimeters apart. there are 23 other genes between the two genes of interest. 23 % of the offspring exhibit recombination between the two genes. 23% of the offspring do not survive. 77% of the offspring exhibit recombination between the two genes.

5. The color of the hull in oat seeds are determined by two genes that independently assort. The black hull phenotype is due to a dominant allele A. The grey hull phenotype is due to a dominant allele B. However, the effect of B is only apparent in the aa genotypes. In other words, the presence of the A allele masks the effect of the genotypes in the B gene. If neither A or B is present, the color of the hull would be white. You take a true breeding white strain (aabb) and cross it with a true breeding black strain (AABB). You let the F1 generation self-fertilize and collected the F2 generation of seeds. a. In the diagram below, please fill out the blue areas. In the rectangles, please fill in genotypes. In the parentheses, fill in proportions of respective genotypes. In the lines, specify the respective phenotypes (black, grey or white).. b. Out of all the black hulled seeds, what proportions have the genotype AaBb? Please show all calculations.. your PO F1 F2 ( A_B_ AABB ( aaB ( ) (…
