[SOLVED] Punnet Squares
The allele for dark hair D is dominant over that of red hair d, and the allele for brown eyes B is dominant over that of blue eyes b. A women is red-haired and has blue eyes. Her husband is dark-haired and has brown eyes.
a) What are the possible genotypes for the woman?
b) What are the possible genotypes for the man?
c) There are 4 possible ways to match the genotypes of these two individuals. In each of the 4 cases, draw a punnet square give all the possible genotypes for their offspring.
So I know that the woman must have alleles: dd and bb
the man must have alleles: DD or Dd and BB or Bb
the 4 ways to match the genotypes are:
dd,bb x DD,BB
dd,bb x DD,Bb
dd,bb x Dd,BB
dd,bb x Dd,Bd
For the match in bold writing, I'm not sure how to draw the punnet square.
