Cellular Genetics: Chromosomes & Meiosis

What is a difference between mitosis and meiosis? Mark ALL that apply!

• Mitosis occurs in the cytoplasm and Meiosis occurs in the nucleus.

• Mitosis results in diploid (2n) daughter cells and Meiosis results in haploid (n) daughter cells.

• Mitosis results in 2 daughter cells and Meiosis results in 4 daughter cells.

• Mitosis makes somatic (body) cells and Meiosis makes gametes (egg and sperm cells).

Examples of cells that undergo MEIOSIS are

• bacterial cells

• animal cells (such as skin cells) and plant cells (such as leaf epidermis cells)

• sexual reproduction cells called gametes

Why do we need meiosis?

• To double the number of chromosomes going into sex cells
• To halve the number of chromosomes going into sex cells
• To triple the number of chromosomes going into sex cells
• To not change the number of chromosomes going into sex cells

• Staying the same

• Similar cells

• Creating identical cells

• Genetic Diversity

In Meiosis, the chromosomes go through crossing over, this leads to:

• Genetic variation

• Identical daughter cells

• To replication of genes
