Meiosis

  • the process that occurs in male and female reproduction systems to produce or form sex cells (sperm and egg)

  • A cell division process of reducing the number of chromosomes.

Multiple Choice

Which statements explain how a mutation in a somatic cell is different from a mutation that occurs in gametes?

1

Somatic cell mutations occur in cells that give rise to gametes.

Gamete mutations occur in cells that result in apoptosis.

2

Somatic cell mutations are maintained in the gene pool.

Gamete mutations are expelled from the gene pool.

3

Somatic cell mutations are generally not passed to offspring.

Gamete mutations are usually passed to offspring

4

Somatic cell mutations will not be expressed by the individual that contains the mutation.

Gamete mutations will be expressed by the individual.

3

Multiple Choice

Homologous pairs - 2 chromosomes (one from mom, one from dad) that have the same length and general appearance

Diploid (2n) - cell has TWO copies of each chromosome (1 from each parent)

46 chomosomes

Haploid (n) - has ONE copy of each chromosome

22 autosomes and 1 sex chromosome

sperm (x or y)

egg (always x)

Diploid (2n)

​Haploid (n)

​(through DNA replication)

​maternal + paternal =
homologous pairs

homologous chromosomes = 2 sister chromatids

1 sister chromatid = duplicated chromosomes
