AP Biology Meiosis and Sexual life cycles

The cells produced via meiosis are called:

• sex cells
• somatic cells
• body cells
• skin cells

This produces 2 identical cells.

• mitosis
• meiosis

What is it called when a sperm and egg meet?

• meiosis
• fertilization
• cell division
• mitosis

What phase is  shown in the picture?

• anaphase 1
• anaphase 2
• metaphase 1
• telophase 1

Meiosis makes sperm and egg cells. In humans, sperm and egg cells each have _____ chromosomes. Therefore a fertilized human egg cell (sperm and egg cell combined) would create a cell with _____ chromosomes.

• 23, 46
• 46, 23
• 2, 4
• 50, 100

What causes genetic variation in meiosis?

• chromosomes lining up
• crossing over of chromosomes
• separation of chromosomes
• chromosomes pulling apart

Unlike mitosis, meiosis in male mammals results in the formation of

• one haploid gamete
• three diploid gametes
• four diploid gametes
• four haploid gametes

When an area of a chromatid is exchanged with the matching area on a chromatid of its homologous chromosome, _________________ occurs

• crossing over
• mutagenesis
• hybridization
• fertilization

What kind of cells are made in MEIOSIS?

• Haploid Gametes
• Diploid Somatic Cells
• Skin Cells
• Liver Cells

Diploid Cells are represented by

• 2n
• n
• 4n
• 1/2 n
