A farmer decides to cross two tomato plants. One of the plants is a dihybrid for genes G and H. The other is homozygous recessive for gene G but homozygous dominant for gene H. Which of the following offspring genotypes would be recombinants? Select all that apply. Select one or more: a. GgHH b. All of the above are recombinant c. ggHH d. None of the above are recombinant e. ggHh f. GgHh

Outline the basic hybridization research done by Mendel when crossing a true breading violet flowered plant with a true breeding white flowered plant? In your answer you should indicate the parental generation, the F1, and the F2 results.

A poultry grower has 2 breeds of chicken, averaging 9 and 5 lbs. inweight. The F1 of the cross between is quite uniform, averaging 7lbs. Of the F2 progeny, 0.4% is as heavy as either parent. a. How much does each effective allele contribute to weight? b. What is the number of polygenes pairs involved in thesecrosses? c. If only those with an average weight of 6-8 lbs. are marketable, whatpercentage of the offspring will yield profit for the grower?

Are two genes linked if not linked to the same marker on a chromosome.? Let's say we want to figure out whether two genes are linked on a particular chromosome so we cross-test them to a marker gene on that chromosome. Gene A is found to have an approximate 50% recombinant frequency so we say it's not linked to the marker. The other gene B however is found to have 40% recombinant frequency with our marker so we say it's linked. Now the question is are the two Genes A and B linked or not? Please explain your reasoning.
