Multiple Select

Select all of the similarities of Mitosis and Meiosis.
BOTH:

• are types of cell division

• result in genetically identical daughter cells

• complete at least one cycle of PMAT

• result in ONLY two cells

• result in AT LEAST two daughter cells

Multiple Select

Mitosis:

• results in two genetically different daughter cells

• results in two genetically identical daughter cells

• completes one cycle of PMAT

• completes two cycles of PMAT

• happens in germ cells

Multiple Select

Meiosis:

• results in at least two (or four) genetically different daughter cells

• results in two genetically identical daughter cells

• completes one cycle of PMAT

• completes two cycles of PMAT

• happens in germ cells

Multiple Choice

A type of cell (egg or sperm) utilized for sexual reproduction.
Produced during Meiosis, these cells have one set of chromosomes.

• Embryo
• Gamete
• Zygote
• Fetus

Match

Match the following

• amount of chromosomes in a human diploid (somatic) cell

• one set of chromosomes (half set)

• two sets of chromosomes (full set)

• two chromosomes in that code for the same genes, but may have different versions (alleles) of those genes
