events in meiosis

Question 1

reductional division; homologous chromosome seperate resulting in two cells with each only haploid chromosomes number

Answer 1

metosis I

Question 2

= chromatin appears as long thin threads

Answer 2

Leptonema

Question 3

synapsis or pairing of homologous chromosomes

Answer 3

zygonema

Question 4

crossing over occurs between homologous chromosome at intersections called _____

Answer 4

Pachynema

chiasmata

Question 5

Leptonema
zygonema
Pachynema

Answer 5

prophase I

Question 6

Chromosomes are now lined up in the metaphase plate , still in homologous pairs

Answer 6

metaphase I

Question 7

• the univalent or homologues in each bivalent (homologous chromosomes) separate from each other
• sister chromatids still intact.

Answer 7

Anaphase I

Question 8

-the spindle apparatus continues to separate the homologous chromosome until they reach the poles

Answer 8

telophase I

cytokinesis

Question 9

-equational division; sister chromatids are separated and four haploid cells are produced

Answer 9

meiosis II

Question 10

chromosomes begin to condense. Nuclear membrane dsiappears

Answer 10

Prophase II

Question 11

chromosomes align at the equatorial phase

Answer 11

metaphase II

Question 12

• The centromeres of sister chromatids seperate

- each sister chromatid now becomes individual chromosome

Answer 12

Anaphase II

Question 13

• chromosomes uncoil and nuclear membranes reappears

- There are now four daughter cells, Each with a Haploid number of chromosomes

Answer 13

Telophase II

Cytokinesis
