Incomplete Dominance and # of Genes

Post by megz1122 » Tue May 09, 2006 8:12 pm

HI. I have a final tomorrow and was working on some problems, when I came across a problem. The problem deals with 2 pure breeding cotton strains being crossed. They are dark red and yellow. 6 phenotypes are seen in the F2: 92 light red, 45 green, 38 dark red, 34 light bronze, 17 dark bronze, and 17 yellow. The F1 is not given. That's part of what needs to be figured out... but first:

How many genes control the color phenotype?it says to explain and give the number of alleles involved.... incomplete dominance is present.

I would greatly appreciate any help!!! Thank you so much! :wink:
