Cell division

Mitosis produces two daughter cells while meiosis produces

• 1

• 3

• 4

• 6

The products of meiosis are

• genetically different daughter cells

• genetically identical daughter cells

Which type of reproduction leads to increased genetic variation in a population?

• sexual reproduction

• asexual reproduction

• cloning

• binary fission

Gametes are

• 2n

• the result of mitosis

• diploid

• haploid

What is represented in this image?

• a mutation in the genes

• segregation of sister chromatids

• crossing over during prophase 1

• homologous chromosomes in anaphase 2

Recombination (crossing over) and independent assortment are two ways that meiosis leads to

• identical daughter cells

• genetic variation

• mutations in DNA

• regulation of the cell cycle

Which best describes cancer?

• mutations in DNA

• hereditary disease

• birth defect

• uncontrolled cell growth

Mitosis occurs in somatic cells while meiosis occurs in

• body cells

• the skin

• reproductive structures only

• every cell besides the brain and spinal cord

The products of mitosis are

• eggs and sperm

• haploid

• n

• 2n

Which statement explains why some people who develop cancer due to exposure to carcinogens will not pass a mutation down to their children?

• the mutation occurred in gametic cells

• the mutation occurred in somatic cells

• the mutation was sex-linked

• the mutation was recessive
