Meiosis Flashcards
where is sperm made
the testes
where are ova made
the ovum
what is the formation of sperm called
spermatogenesis
what is the formation of ova called
oogenesis
how do both spermatogenesis and oogenesis occur
due to a type of cell division called meiosis
what type of cell division is meiosis known as
reduction division
why is meiosis known as reduction division
Because it reduces the number of daughter cells by half
what is a diploid cell
consists of 46 chromosomes
what is a haploid cell
consists of 23 chromosomes
what acronym do we use for meiosis
IPMATM2A2T2
what acronym do we use for mitosis
IPMAT
what is the chiasma
the chiasma is where each homologous chromosome touch and joins together
Draw diagrams to describe the process of mitosis and meiosis

how is meiosis different to mitosis
- Parent cell divides twice
- Four daughter cells are reproduced (instead of 2)
- Chromosomes number is halved (diploid cells divide to become haploid cells
- The daughter cells are not genetically identical
- only occurs in sperm and ova
what cells are produced through mitosis
somatic cells (body cells)
