B13.2 Meiosis

Question 1

What does cell division produce ? What do these on stub and where does this process often take place

Answer 1

Gametes
Each containing half the genetic material know as HAPLOID
Occurs in testicles and ovaries

Question 2

What do gametes (sex cells) combine to form?

Answer 2

Combine together to from a unique full set a chromosomes
Egg+sperm

Question 3

What are the stages of Meiosis ?

Answer 3

1 parents cell (diploid) with 46 chromosome
DNA replicated to 92 with genes being mixed up
Cell division twice (diploid) with each having a random mix of DNA
4 daughter cells with half amount of DNA

Question 4

What are the similarities between mitosis and Meiosis ?

Answer 4

Both
- parents cells have 46 chromosomes
- both replicate the DNA

Question 5

What are the differences between Meiosis and Mitosis ?

Answer 5

Differences
- mitosis has 1 division, Meiosis has 2
- mitosis has 2 daughter cells, meiosis has 4
- mitosis daughter cells have 46 chromosomes, meiosis has 23
- mitosis produces identical but meiosis produces genetically different daughter cells
