genetic

Post by taata » Thu Jul 07, 2005 11:59 pm

In a cross between a black guinea pig and a white guinea pig, all the offspring were black. The F2 generation was made up of 18 black and 5 white guinea pigs.
a) What does this information tell you about coat colour inheritance in guinea pigs?
b) Explain the numbers of black and white guinea pigs in the F2 generation.
c) What will the offspring be like if two white F2 guinea pigs are mated?


:? :) :cry:

Even if your read the most elementary genetics book you can find in the world you will find the answer

I think mithril tried to say that he /she is in trouble because of not remembering anything. I don't think he tried to say anything about your attitude towards him/her Am I right Dave?

I'm sorry if I wasn't clear, but this is the basic of basics. If you don't know this stuff...you will fail. Sorry guys but this is the fundamentals and you have to have these memorized.
