Cell Division for Gametes - Meiosis (Phases)

Question 1

What is Meiosis?

Answer 1

Meiosis is a cell division process that produces eggs and sperm, in which a parent cell produces four haploid daughter cells. Meiosis is often referred to as a reduction division as it reduces the number of chromosomes in gametes to half that of in somatic cells.

Question 2

What is Interphase?

Answer 2

Interphase refers to the cells normal everyday functions and is where cell division starts and chromosomes, genetic material, replicates

Question 3

What is the phase where spindle fibres dissolve and a new membrane starts to form?

Answer 3

Telophase 1

Question 4

What happens in Metaphase 1?

Answer 4

Chromosomes pair up along the ‘equator’ and a centromere attaches each chromosome to a spindle fibre.

Question 5

What occurs in Prophase 1?

Answer 5

Chromosomes condense, spindle fibres appear, nuclear membrane dissolves, and crossing over occurs.

Question 6

What happens in Anaphase 1?

Answer 6

chromosome move to the ‘poles’

Question 7

what phase is it when there is now two haploid cells and new spindle fibres appear?

Answer 7

Prophase 2

Question 8

What happens after prophase 2?

Answer 8

The next phase is metaphse 2, where the chromosome attach to the spindle fibres and line up along the equator.

Question 9

what occurs in Anaphase 2?

Answer 9

In Anaphase 2, the centromere splits and the chromatid move to opposite poles

Question 10

What happens in Telophase 2?

Answer 10

The spindle fibres dissolves, the new membrane forms and each cell divides
