| Is there any way of telling which chromosome will go to which gamete in meiosis? | No, it is random |
| Do all cells in an organism that reproduces sexually undergo meiosis? | No, just the germ-line cells |
| Where does meiosis occur in the human body? | In the testicles and ovaries |
| Why is it that you can calculate the probability of a particular allele being in a particular gamete? | Because chromosomes segregate randomly in meiosis |
| In pea plants and other sexually reproducing organisms, how can new combinations of alleles easily be formed? | By combining male and female gametes |
| Why does about half of your DNA come from each parent. | Because you get half of your chromosomes from each parent. (Chromosomes are made of DNA) |
| What chromosome makes mammals male? | The Y chromosome. Remember: Y makes a guy. |
