An ecologist has been following three single gene traits in laboratory breeding experiments of frogs. Texture and Color of the skin and the extent of webbing between the digits. The dominant traits in each case are Warts (vs smooth), Red (vs green) and Webbed (no-webbing). Wild type frogs have smooth, green skin with webbed feet. We want to breed a frog that has all three mutant phenotypes. Cross 1 – We made a dihybrid frog by crossing an inbred color mutant with an inbred texture mutant. Cross 2 - We crossed this dihybrid with an inbred non-webbed mutant. Question: What fraction of progeny will be the desired triple mutant from cross 2. Write out the work flow to solve this problem.

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,

A researcher studied 6 independently assorting genes in a plant. Each gene has a dominant and a recessive allele: R black stem, r red stem; D tall plant, d dwarf plant; C full pods, c constricted pods; O round fruit, o oval fruit; H hairless leaves, h hairy leaves; W purple flower, w white flower. From the cross Rr Dd Cc Oo Hh Ww (male) x Rr dd Cc oo Hh ww (female): How many different kinds of gametes can be formed from both parents? What is the frequency of obtaining a sperm cell with at 3 dominant and 3 recessive alleles? How many phenotypes are possible among the progeny? How many genotypes? What is probability of obtaining a black, dwarf, constricted, oval, hairy, purple phenotype in the progeny? What is probability of obtaining progeny with exactly same genotype as the female parent? As the male parent? If both parents were heterozygous for all genes, what is the probability of obtaining progeny with at least 2 recessive traits? From the cross in (f), will there be…
A- Using a Punnett Square show a cross between a homozygous red fox with a homozygous white fox. Let red be dominant. Give the genotype and phenotype for F1 and F2 generations. B- Using a Punnett Square show the cross between a heterozygous gray skunk with a homozygous white skunk. Let gray be dominant. Give the genotype and phenotype for F1.

You are a biologist studying the local butterfly population. You've discovered 4 white (albino) butterflies. You mated each one with a wildtype butterfly and kept the lines separately. After several generations of back crosses, you've managed to create 4 lines of white butterflies. How can you tell if they represent mutations in the same gene or different genes? What crosses would you do? What results would you expect? (using complementation analysis).
Let's continue with these two genes that control the color and texture of tomatoes. Allele "R" generates a red coloration, and is dominant. Allele "r" generates a green coloration and is recessive. Allele "S" generates a smooth texture, and is dominant. Allele "s" generates a rough texture and is recessive. You now decide to cross your dihybrid RrSs but this one with a tomato with Rrss. RrSs x Rrss What is the probability of getting Red tomatoes with Rough texture in this new cross? Assume complete dominance and 100% penetrance and expressivity. 9/16 3/8 1/4 1/16 3/16 1/8 x 1/2

In chickens comb shape is controlled by a pair of interacting unlinked gene loci each with two alleles, R,r and P,p. These genes interact in such a way to give four possible phenotypes, as follows: Walnut - requires one each of the dominant genes. Rose - requires a R and homozygous recessive for the p gene. Pea - requires a P and homozygous recessive for the r gene. Single - requires fully homozygous recessive. If two walnut comb chickens are mated and produce 1,000 offspring, and some of these 1,000 offspring are of the single combed variety. Please answer the following questions: a.___ How many of rose comb phenotype would you expect in the 1,000 offspring? A. 563, B. 438, C. 360, D. 188, E. 63 b.___ The evidence provided would result in the conclusion that the inheritance of comb form in chickens is a good example of a polygenic mode of inheritance. True OR False c.___ What would be the best way to describe the cross involved? 1. A true dihybrid cross…
