16
Q

Prophase I in Meiosis

A

chromatin condenses to chromosomes
nuclear envelope breaks down
spindle microtubules begin to form

homologous chromosomes pair up

17
Q

paired up homologous chromosomes

A

bivalents

18
Q

crossing over

A

entangling of chromatin as a result of movement through cytoplasm

19
Q

homologous pair of chromosomes

A

chromosomes that have the same information on them (same genes) like haircolour
but: alleles can be different like brown or blonde

20
Q

diploid

A

referring to set of chromosomes

46 one-chromatid-chromosomes/ two-chromatid-chromosomes

21
Q

haploid

A

referring to set of chromosomes

23 one-chromatid-chromosomes/ two-chromatid-chromosomes

22
Q

Is the repair of cells a role of mitosis?

A

No, not the actual cell is repaired by mitosis, but tissue is repaired by producing new cells

23
Q

Does cloning involve fertilization?

A

no
