Tri-Hybrid Punnet Square

[From: ] [author: ] [Date: 12-02-03] [Hit: ]
Just create a Punnett square for Aa x Aa, another for Bb x Bb and another for Cc x Cc. And then go through, methodically, and write them all down.If you want to write them all down,......
What would be the Genotypes of a trihybrid cross between AaBbCc x AaBbCc? I know it will be a lot.

Do you know how to create three different Punnett squares instead of a huge one? It will make your life easier if you haven't used them.

Just create a Punnett square for Aa x Aa, another for Bb x Bb and another for Cc x Cc. And then go through, methodically, and write them all down.

If you want to write them all down, that's one thing. But if you want to know the total NUMBER of different genotypes it's easier, especially since it's like the "thing" is being selfed.

Aa = 3 different genotypes possible (these could be seen if you did the Punnett square as I mentioned above). Bb = 3 different genotypes possible. Cc = 3 different genotypes possible. So it's 3*3*3=27.

AaBbCc each parent will produce 8 types of gametes

ABC, ABc, AbC, Abc, aBC, aBc, abC, abc

Try F1 cross in punnet suare using these gametes you will get it
