Phenotypes/Genotypes .... Punnet Square ???

Postby Authentic » Thu Mar 12, 2009 1:15 am

Ok, so I have this homework assignment that I understood in the classroom as I went along
with the teacher, but as soon as I got home to do it, I forgot the steps to the problem. Here's
the problem:

In plants, purple(P) is dominant over white(p) and bitter(B) is dominant over sweet(b). Finally,
Large(L) is dominant over small (l).
If a heterosygous plant cross pollinated with another heterosygous plant,
how many white, sweet planyts are in f1? (the "1" in "f1" = subscript 1)
Choose two plants and crossbreed them for the f2 generation. (the "2" in "f2" is a subscript 2)
How many plants are homosygous ?? Give ratios for the offspring.

I don't remember how to get the "f1". I also forgot about what information to use
to put in the Punnet Square. Can I get some help please ?? It's to be done tomorrow at
10:00 am and I'd like to get a response that I can understand that will help me set up and
solve this problem. Thanks. =)
