3. Short-tailed pup distribution. In mice, the dominant T allele results in a short tail. Homozygous T/T genotype is lethal, which means mouse embryos with this genotype die before they are born. 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?

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.
