3. Page 1 and 2: Vocabulary
Meiosis- cell division in which eggs and sperm are made
Gamete- eggs and sperm cells
Oogenesis- the production of eggs
Spermatogenesis- the production of sperm
Diploid Cell- a cell with two copies of each chromosome
Haploid Cell- a cell with one copy of each chromosome (Gametes)
Human Chromosomes: 23 different chromosomes (Haploid Number)
46 chromosomes in most cells (Diploid Number)
Zygote- after the sperm fertilizes the egg until eight weeks, diploid cells
Fetus- an unborn individual from eight weeks after fertilization until birth
Allele- a form of a gene (The gene would be eye color, the alleles would be brown and blue)
Homologous Chromosome- pairs of chromosomes with the same genes, though they may have different alleles
Tetrad- A pair of homologous chromosomes.

5. Page 4: Interphase
The cell is doing it’s regular business. Three distinct parts Gap 1: The cell does it’s regular business S phase: Chromosomes Replicate Gap 2: The cell does it’s regular business before going through cell division

6. Page 5: Meiosis I - Prophase I
DNA condenses into chromosomes
Chromosomes pair up into Tetrads
Crossing-over occurs
Nuclear Membrane disappears

7. Page 6: Meiosis I – Crossing Over
Homologous Chromosomes exchange genetic material with non-sister chromatids resulting in new combinations of alleles

16. Page 15: Differences Between Oogenesis and Spermatogenesis
Oogenesis Creates Egg Cells Begins before Birth Creates 1 Haploid Cell Discards other products of Meiosis (called Polar Bodies) Spermatogenesis Creates Sperm Cells Begins at Puberty Creates 4 Haploid Cells Discards Nothing
