Hint on this Genotype Question.

Post by Procrastinate » Sun Sep 05, 2010 8:39 am

How many kinds of gametes can be produced by an individula of genotype AaBaCCddEeFF?

I am having trouble understanding and starting off. Could someone explain perhaps the first step to help get me started?

I guess it's AaBbCCddEeFF.
So, you can combine each version of allele you have (but one from each, so you must always have ABCDEF (not mattering size now)). Well, but where you have only one version (CC, dd and FF) it doesn't matter, which one you get.
So, you combine A, B and E. How many combinations you can get from these three?

Cis or trans? That's what matters.

I would say three.

no, you have A or a, B or b and E or e and you can combine them, as you want (but always have to have one A/a, B/b and E/e, i.e. e.g. ABE or abe or ABe or AbE etc. ;)
So it's 2^x where x is the number of freely combined genes (in your case 3), OK?

Oh, I get it. I ended up with 8 different types of gametes.
