C. 2 Different Daughter Cells
D. 2 Similar Sister Cells
3. What stage of mitosis is the cell in to the right in?

3. Sexual Reproduction Requires at least two parents
Offspring shares traits from parents
Chromosomes: carries genetic information (genes)
Increases Variation
Variation – change

4. 2x

5. Stages of Meiosis (Sexual Reproduction)
Prophase I
Metaphase II
Anaphase I
Telophase I
Prophase II
Anaphase II
Telophase II

6. Your Life Summed up! Total number of Chromosomes: 46
Each parent donates 23 each.
Sex Chromosomes: X and Y
Male: XY
Females: XX

7. Your Life Summed up!
Diploid (2N)- Somatic Cell with 46 chromosomes (human)
Polyploid (4N) – Double amount of DNA/Chromosomes; Humans 4692
Haploid (n)- Half the amount of DNA; 4623

8. 1. Prophase 1 Chromosome number doubles
46  92
Homologous Chromosomes Crossover
Increases genetic variation

9. Metaphase 1 Homologous Chromosomes align in the middle.
Spindle Fibers attach to each side.

11. YOU YO DADDY’S SON!...or Daughter?
Your dad controls your sex
Mom – XX (Mom can only donate a female chromosome)
Dad- Xy (Dad can donate a x (female) or a y (male))
