A

vasectomy and tubal ligation

Q

name a few types that would be considered as a barrier for birth control

Q

during what stage of the cell cycle does DNA replication occur?

A

synthesis

54
Q

name the phase of cell division during which separation of sister chromatids occur.

A

anaphase

55
Q

by what process does the cytoplasm of a human cell separate?

A

cytokinesis

56
Q

name the phase of cell division when duplicated chromosomes first appear

A

prophase

57
Q

where in humans would you expect to find meiosis taking place?

A

ovaries/testes

58
Q

if there are 13 pairs of homologues in a primary spermatocyte, how many chromosomes are there in a sperm?

A

13

59
Q

what term refers to the production of an egg?

A

oogenesis

60
Q

during which type of gametogenesis would you see polar bodies?

A

oogenesis

61
Q

what do you call chromosomes that look alike and carry genes for the same traits?

A

homogylous

62
Q

if homologues are separating, what phase is that?

A

anaphase 1

63
Q

if the parental cell has 24 chromosomes, how many does each daughter cell have at the completion of meiosis II?

A

12

64
Q

name the type of cell division during which homologues pair

A

meiosis

65
Q

name the type of cell division described by 2n –> 2n

A

mitosis

66
Q

does metaphase of mitosis, meiosis I, or meiosis II have the haploid number of chromosomes at the equator of the spindle?

A

meiosis II

67
Q

meiosis functions to reduce chromosome number. when during the human life cycle is the diploid number of chromosomes restored?

A

fertilization

68
Q

how does the alignment of chromosomes differ between metaphase of mitosis and metaphase of meiosis I?

A

1) individual chromosomes 2) chromosome pairs

69
Q

what are the 3 ways in which there is randomness in meiosis?

A

1) crossing over - longer chromosomes are more likely to have more mixing than shorter ones. is random during synapses at prophase I. 2) the way the homologues/chromosomes pairs line up in metaphase I is random. 3) random which sperm fertilizes which random egg that has been ovulated. A variation in population
