Meiosis

• carry traits that make you who you are

• the actual fusion of the egg and sperm

• process of cell division that makes gametes

• 2 identical copies of the same chromosome

• separation of sister chromatids

• separation of homologous chromosomes

• determine your biological sex

Fertilization

• the cell divides in two

• sex cells

• body cells

• the actual fusion of egg and sperm to form a zygote.

Somatic Cells

• fusing of genetic information

• body cells; full copies of DNA

• sex cells; half of the DNA

• the actual fusion of the egg and sperm

• sexual reproduction

• sex chromosomes

• gametes

• prophase

What is the difference between Meiosis and Mitosis?

• Mitosis uses haploid cells for sexual reproduction. Meiosis uses diploid for growth and repair.

• Meiosis uses haploid cells for sexual reproduction. Mitosis uses diploid for growth and repair.

Prophase II

• nuclear membrane dissolves, spindle fibers form

• sister chromatids line up in the middle

• sister chromatids separate

• sister chromatids pull to opposite ends of the cells

Metaphase II

• sister chromatids pull to opposite ends of the cells

• sister chromatids separate

• sister chromatids line up in the middle of the cell

• nuclear membrane dissolves; spindle fibers form
