In tomatoes, two alleles of onegene determines whether the plant has purple (P) or green (G) stems, and a separate, independent gene determines whether the leaves a "cut" (C) or "potato" (Po). Five crosses of tomato plants (with the phenotypes show) give the following results:

Number of Progeny
Parental
Mating Phenotypes P, C P, Po G, C G, Po
1 P, C x G, C 321 101 310 107
2 P, C x P, Po 219 207 64 71
3 P, C x G, C 722 231 0 0
4 P, C x G, Po 404 0 87 0
5 P, Po x G, C 70 91 86 77

a. Determine which alleles are dominant.
What are the most probable genotypes for the paren'ts in each cross?

The correct answer will be G/G ; P/p x g/g ; P/p

Explanation:

Let G be the dominant allele for stem color and g be the recessive allele for stem color. Let P be the dominant allele for leave shape and p be the recessive allele for leave shape.

the cladogram shown here shows similarities and differences among several classes of vertebrates. anatomically, the four have limb structure as their common ancestor. we might separate the mammals from the other three classes because they a) divergent; do not lay eggs b) identical; are warm-blooded c) varied; a four chambered heart d) homologous; have mammary glands
