The cells produced via meiosis are called:

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

This produces 2 identical cells.

• mitosis
• meiosis

A human usually has xx amount of chromosomes.

• 6
• 22
• 4
• 46

What is it called when a sperm and egg meet?

• meiosis
• fertilization
• cell division
• mitosis

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

If the Diploid number of Carrots is 18, the haploid number is

• 18
• 9
• 27
• 36

Which process and type of resulting cells are represented?

• mitosis, gametes
• mitosis, body cells
• meiosis, gametes
• meiosis, body cells
