1. During meiosis, chromosome number is reduced through three rounds of cell division.
2. A gamete has one-half the number of chromosomes of a regular body cell.
3. A Woman with an X-linked dominant genetic disorder will have children who have a 50% chance to be affected by the trait also, regardless of their gender
4. Sexual reproduction would be more advantageous than asexual reproduction for organisms living in an environment that is diverse and undergoes frequent changes.
5. Meiosis occurs during both sexual reproduction and asexual reproduction.
6. Recent research suggests that beneficial mutations accumulate faster when species undergo sexual reproduction rather than sexual reproduction
7. A man whose parents both have heart disease is worried that he too will have heart disease. It is possible for him to reduce his risk of the disease by maintaining a healthy diet and by engaging in frequent exercise.
8. Homologous chromosomes are two chromosomes with identical DNA sequences.
9. Light energy is trapped and converted into chemical energy during the citric acid cycle.
10. Heterotrophs produce their own food.

1) False. First, since meiosis is made up of two rounds of cell division- not three. Also, your chromosome number doesn't decrease- it's just divided up into four daughter cells, all dissimilar.
2) True! Gametes have to have half the number of chromosomes of a regular body cell, because when the gametes "fuse together" to create a zygote, the zygote has the normal number of chromosomes, 26.
3) True! Use a punnet square to prove it.
4) Definitely true. Asexual reproduction makes it so that the offspring is an exact clone of the parent: aka, no mutations, aka, no evolution. In a constantly changing environment, natural selection would knock that baby right out of the park- if you can't adapt, you're dead.
5) False- meiosis is just sexual reproduction. Mitosis is asexual reproduction. Think of bacteria.
