In snapdragons tallness (T) is dominant to dwarfness (t).
Red flowers are produced by RR and white flowers by rr but
the heterozygous Rr is pink. A dwarf red snapdragon is
crossed to a homozygous tall plant with white flowers. What
is the phenotypic ratio of the F1? the F2?

dwarf, red snapdragon: ttRR * homozygous tall,white flowers
TTrr
F1: tR, Tr gametes
phenotypic ratio : 1:2:1
F2: TR, Tr, tR, tr gametes
9:3:3:1 .

In cucumbers normal leaves (N) are dominant to curled leaves (n) and elongated fruit (L) is dominant to spherical fruit and these genes are linked on the same chromosome. If a pure-breeding normal-leaved, elongated fruit cucumber is crossed with a curled-leaved, spherical fruit cucumber, what will be the phenotype of the F1? the phenotypic ratio of the F2?

In mice colored coat is dominant to albinism. Sniffles, a male mouse with a colored coat is mated to Esmeralda, an alluring albino. The resulting litter of six young all had colored fur. The next time around Esmeralda was mated with Whiskers, who was the same color as Sniffles; some of this litter were white. a)What are the probable genotypes of Sniffles, Esmeralda, and Whiskers? b) If a male of the 1st litterwas mated to a colored female of the 2nd litter, what phenotypic ratio might be expected among the offspring? c)What would be the expected results if a male of the 1st litter was mated to an albino from the 2nd?
