Meiosis and Independent assortment

Question 1

What is Meiosis?

Answer 1

nuclear division that result in 4 cells that have half the DNA of the original organism, produces gametes, allows for the fusing of to haploid nuclei to restore the full number of chromosomes and make a diploid nucleus

Question 2

What is Independent assortment?

Answer 2

how different genes independently separate from one another when reproductive cells develop and different combinations of alleles are present in each gamete

Question 3

What are the phases in Meoisis?

Answer 3

Prophase I
Metaphase I
Anaphase I
Telophase I
Prophase II
Metaphase II
Anaphase II
Telophase II

Question 4

What happens in Meiosis I?

Answer 4

genetic variation is created by crossing over of Homologous chromosomes and when they arrange randomly in pairs along the equator in metaphase I

Question 5

What happens in Anaphase I?

Answer 5

the homologous pairs are separated to each pole of the cell, creates 2 daughter cells which contain one chromosome from each homologous pair

Question 6

What happens in Meiosis II?

Answer 6

follows the same pattern as mitosis where the chromatids of each chromosome are separated producing four genetically different haploid daughter cells

Question 7

When does Independent assortment happen?

Answer 7

Metaphase II
