Genetic Cross

Post by pohely » Sun Oct 21, 2007 8:49 pm

In Shorthorn cattle, both red coat color and white coat color are true breeding. Crosses of red X white produce progeny that are uniformly reddish brown but thickly sprinkled with white hairs; this tpe of coat color is called "roan". Crosses of roan X roan produce 1/4 red: 1/2 roan: 1/4 white. What kind of genetic hypothesis can explain these data?

Have you considered reading your textbook for this question and the 2 others (that I locked).? It might help, and then you can come to us with your suggestion of answer and/or problems. And then we will help you.

Yeah. Theoretical concepts must be reviewed.

Think about how many genes there could be.
