Q

Prophase I

The pairing of homologous chromosomes (synapsis) begins;

A

zygotene

17
Q

A pair of homologous chromosomes

A

bivalent or tetrad

18
Q

The process of pairing of homologous chromosomes

A

synapsis

19
Q

Exchange of genetic material

A

crossing-over

20
Q

Prophase I

A bivalent has formed and crossing over has occured.

A

Pachytene

21
Q

The area of contact between two chromatids

A

chiasma

22
Q

Prophase I

the tetrad tends to repel each other; the chiasma become distinct

A

diplotene

23
Q

Prophase I

The nucleolus disappear and the nuclear membrane begins to break down.

A

Diakinesis

24
Q

A protein structure that forms between homologous chromosomes (two pairs of sister chromatids) during meiosis and is thought to mediate synapsis and recombination

A

Synaptonemal complex
