1. Occasionally homologous chromosomes fail to seperate during meiosis I. Using the hypothetical example of an adult organism that has two pairs of chromosomes, escribe the chromosomal makeup of the eggs that would result from this error in meiosis.

2. If normal human sperm fertilized the eggs described above (in question 1), what would the chromosomal makeup of the resulting zygote be?

3. How do independent assortment, crossing-over, and random fertilization affect the rate of evolution?

4. A student states that organisms that reproduce asexually are at a disadvantage in a stable environment. If you agree with this hypothesis, name one or more of its strengths. If you disagree, name one or more of its weaknesses.
