4) The alleles for a certain gene on the homologous chromosomes (remember, in a homologous pair, one chromosome comes from mom and one from dad), will possibly or certainly be different. Hint: For example, if the gene for eye color is on each homologous chromosome, ask yourself whether the alleles (blue eyes, green eyes, brown eyes, etc.) could possibly be different or would certainly be different for each chromosome.

5) A chromosome with ONE chromatid will make a copy of itself during the S or G1 phase of Interphase.

6) The goal of mitosis or meiosis is to make two exact copies of the cell
8) In prophase I of meiosis or mitosis, the homologous chromosomes come together to make a tetrad.
9) In a tetrad during Prophase 1 or Metaphase I, parts of the homologs (the chromosomes of a homologous pair) switch places in a process called crossing over.

10) There is or is not another interphase before the start of Meiosis 2.

12) In males, the 4 haploid or diploid cells at the end of Meiosis 2 become 4 sperm cells.
