First Activity:

1. The short-haired allele is dominant to the long-haired allele so you couldn't determine the long-haired genotype of a short-haired cat just by looking at it. A heterozygous genotype would override the recessive allele.

2. You could determine the genotype of an Agouti cat by doing a test cross. If it is homozygous dominant than the offspring will all have striped fur. If it is heterozygous than the offspring will be 50% striped and 50% not striped.

3. They want to figure out why and how these genes don't resemble neither homozygotes.

4.  BB x BB= BB, BB, BB, and BB ( 100% of the offspring will be black)

5. Maybe the pattern on its fur can be used as a camouflage, to hide from its predator. And since it can't be seen they could live longer.

6. Yes, because the dominant white allele overrides all of the other pigmentation genes.

7. Some factors that determine allele frequency are eye color and fur color. No, it is not always the most frequent allele at a locus.

8. Their genotype is Tt. And maybe it will increase over time.

Second Activity:

1. The results of both experiments seem to be completely different.

2. Compared to the second experiment, it seems like Mendel's results were probably set up.

Third Activity:

1.a. not possible
   b. either A+, A-, O+, or O-
   c. either A+, A-, AB+, or AB-
   d. either A, AB, B, or O
   e. either A, AB, B, or O
   f. unlikely

2. No, because the child's blood must have some kind of "resemblance" to its' parent's blood
