They both came from the organism's mother.

They both came from the organism's father.

One chromosome came from the organism's parents.

Neither chromosome came from the organism's parents.

Chromosomes, Homologous chromosomes

Chromatids, Homologous Chromosomes

Chromatids, Chromosomes

They both separate chromatids

1 pair in each cell

2 pairs in each cell

1/2 a pair in each cell

2 pairs of pears

Yes!

Not yet!

The copy machine is broken

The chromosomes are still inside the nucleus so they can't replicate

The cell doesn't have enough energy to replicate DNA again

The ending cells would end up with too much DNA

True!

False, only in Meiosis I

False, only in Meiosis II

Chromatids

Chromosomes

Homologous Chromosomes

Centrioles

During reproduction the sex cells will combine to create an embryo with a full set of DNA

Because it takes 2 eggs cells to make an embryo so it will end up with 3 sets of DNA

Because humans reproduce asexually so when it does mitosis all the DNA will double in each cell when making the new human

Because each cell will have the DNA duplicated again in the 3rd round of meiosis
