Meiosis

Multiple Choice

Why would mitosis not be suitable for making gametes?

• the daughter cells in mitosis contain 23 chromosomes

• The daughter cells in mitosis contain 46 chromosomes

Multiple Choice

where in the body are gametes created?

• blood

• sex organs

• everywhere in the body

Ova and sperm cells are haploid cells. They only have one of each chromosome. Therefore in humans these cells contain 23 chromosomes only.

sex cells

known as diploid cells. They contain two sets of each chromosome. Diploid cells in humans contain 46 chromosomes.

normal cells

haploid or diploid

Multiple Choice

• Diploid

Multiple Select

which of the following is correct for Meiosis?

• The new cells contain the exactly the same chromosomes and the same genes as their parents

• The new cells contain half a set of chromosomes

• The purpose of this cell division is the production of gametes by the sex organs

• This type of cell division produces diploid cells

Multiple Select

which of the following is correct for Meiosis?

• 4 new cells are produced at the end of cell division

• The purpose of this cell division is for growth, repair and replacement of damaged cells

• This type of cell division produces haploid cells
