e. Gene 2 has alleles "F" and "f" where F is dominant to f. We do not know if the genes are linked. The cross EEFF × eeff is made, and the F1 is then test-crossed with the recessive parent. Note the genotypes are written without slashes and semi colons because we do not know if the genes are on the same chromosome or different. a. What is the genotype of the F1 and the individual used in the test-cross? Below are the progeny phenotypes and proportions from the F1 testcross. b. What are the full progeny genotypes? Which progeny phenotypes are the result of inheriting a parental or recombinant combination of alleles? E F 2/6 (=0.33) E f 1/6 e·F 1/6 e f 2/6 c. Do the results above suggest the two genes are linked? Why or why not? If linked, how far apart are the loci?

Homozygous t/t is normal, with normal tail. A cross between two short-tailed mice produces a litter of 5 pups. a). What are the genotype(s) of the two short-tailed mice used in the cross? b). What are the possible genotypes and phenotypes of the 5 pups? What are their perspective ratio?

3. In radishes, flower color may be red, purple or white. The edible portion of the radish may be long or oval. When only flower color is studied, red X white yields all purple. If these F, purples are interbred, no dominance is evident, and the F₂ generation consists of 14 red: 2 purple: 4 white. Regarding radish shape, long is dominant to oval in a normal Mendelian fashion. Determine the F, and F₂ phenotypes from a cross between a true breeding red long radish and one that is white oval. Be sure to define all gene symbols initially.

1 Name Non-Mendelian Genetics Part 1: Incomplete Dominance In radishes, the gene that controls color exhibits incomplete dominance. Pure-breeding red radishes (RR) crossed with pure- breeding white radishes (rr) make purple radishes. What are the genotypic and phenotypic ratios when you cross a purple radish with a white radish? Genotype Probabilities: Phenotype Probabilities: Crosses between a yellow rat and a yellow rat always produce yellow rats (YY). Crosses between a white rat and a white rat always produce white rats (yy). But crosses of a white with a yellow produce a cream rat.
