2
Which kind of cell division would be uses to create skin?
Mitosis
Which kind of cell division would be used to make a baby?
Meiosis
A sex cell (in humans: sperm for males, and eggs for females)
Gamete
A two-step process of cell division that is used to make gametes (sex cells)
Meiosis
Cell that contains two sets of homologous chromosomes
Diploid (2n)
Cell that contains only a single set of genes
Haploid (n)
What is the purpose of Meiosis?
To create sex cells
Where does Meiosis occur?
Reproductive cells
During meiosis, when does the ploidy (number of sets of chromosomes) get reduced from diploid (2n) to haploid (n)?
telophase I
What occurs during meiosis II?
The separation of sister chromatids
