Meiosis

Question 1

Homologous meaning

Answer 1

Chromosomes pairing via meiosis having the same structural features and pattern genes.

Question 2

Stages of Meiosis

Answer 2

• Interphase
• Prophase (I and II)
• Metaphase (I and II)
• Anaphase (I and II)
• Telophase (I and II) and Cytokenisis

Question 3

What happens in the interphase

Answer 3

prior to undergoing meiosis, a cell goes through an interphase period in which it grows, replicates its chromosomes, and checks all of its systems to ensure that it is ready to divide. (G1, S, G2)

Question 4

What happens in the Prophase

Answer 4

During prophase I, the chromosomes condense, and the nuclear envelope disintegrates, spindle fibres form

Question 5

What happens in the Metaphase

Answer 5

The homologous pairs of chromosomes align on either side of the equator, and spindle fibresattach to the centromere of each pair of cromatids.

Question 6

What happens in the Anaphase

Answer 6

Homologous chromosomes are pulled by the spindle fibres to opposite poles. This causes genetic variation.

Question 7

What happens in the Telophase

Answer 7

Nuclear envelopes reform and chromosomes uncoil. Cells then undergo Cytokenisis. These are now haploid cell.

Question 8

What is cytokinesis

Answer 8

The division of the cell membrane and cytoplasm
