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?

Hydrilla (hydrilla verticillata) is an invasive aquatic plant and one of the most serious aquatic pests in florida. hydrilla has already been introduced to hundreds of bodies of water throughout florida, hydrilla is difficult to control because it grows rapidly and survives in many different water depths and conditions. hydrilla • describe how hydrilla affects native plant and animal species. include both a biotic and an abiotic limiting factor. • suggest one biotic and one abiotic recommendation that could slow the spread of hydrilla
