6.) Another two factor cross in which the two traits are close together on the same chromosome. Again, let's assume that hair color and texture are close together on the same chromosome. As a reminder: Black B, and yellow hair b Wiry hair W, and smooth hair = w You have a heterozygote male, and you know that his dad was homozygous dominant for both traits, and his mom had smooth yellow fur. You are considering breeding this dog with a double homozygous recessive female. What are the possible gamete genotypes for both your dog and the one you are considering mating him with? Dog: BbWw BW Female dog: bhuw bW bw How many offspring (out of 16) would you expect will have smooth yellow fur? BW Bu b 4out of llo 7.) 7. Crossing over Now let's pretend that hair color and hair texture are on the same chromosome, but this time, they are located far enough apart that crossing over can occasionally occur. Black is dominant (B), and yellow hair is recessive (b) Wiry hair is dominant (W), and smooth hair is recessive (w) Let's assume once again that both parents are double heterozygotes for the two traits (BbWw), and the B and W alleles are on one homolog, and b and w are on the other: a. Write down again the possible phenotypes of the children you would expect to see in the case where these two traits were close together on the same chromosome: вU" b. If the traits are a little farther apart, and crossing over occurs, what additional phenotypes would you expect to see?

Say you encounter a problem on an exam with a cross between two double heterozygotes, and the phenotypes ratios of the offspring are given.
