Meiosis

Question 1

Meiosis

Answer 1

a single cell divides twice to produce four gametes containing half the original amount of genetic information

Question 2

Diploid germ cells

Answer 2

Specialized germ cells that only produce gametes

Question 3

homologous chromosomes

Answer 3

chromosomes which contain the same genes in the same order along their chromosomal arms

Question 4

somatic cells

Answer 4

any cell of the body except sperm and egg cells

Question 5

gametes

Question 6

haploid

Answer 6

a cell, usually a gamete, that contains only a single set of unpaired chromosomes

Question 7

sexual reproduction

Answer 7

a regaining of diploid status via the donation of haploids from both parents.

Question 8

spermatogenesis (how many gametes produced?)

Answer 8

The process of a male diploid germ cell undergoing meiosis and producing 4 genetically diverse sperm cells which are gametes

Question 9

oogenesis (how many gametes produced?)

Answer 9

The process of a female diploid germ cell undergoing meiosis and producing 1 genetically diverse egg cell which is a gamete and 3 polar bodies which are reabsorbed

Question 10

Crossing Over

Answer 10

the exchange of genetic material between non-sister chromatids of homologous chromosomes during meiosis

Question 11

What is the difference between Meiosis 1 and 2?

Answer 11

Meiosis I is a reduction division where only one member of a homologous pair enters each daughter cell which becomes halploid. Meiosis II only splits up sister chromatids.

Question 12

Independent assortment

Answer 12

the alleles of two (or more) different genes get sorted into gametes independently of one another
