Meiosis 1 Flashcards
1
Q
What does prophase 1 look like?
A
Chromosomes have a shortened end and thickened end, each chromosome visible as two chromatids held together by a centromere.
2
Q
What happens during prophase 1?
A
The homologous pairs come together to form tetrods.
3
Q
What happens during metaphase 1?
A
The chromosome pairs arrange themselves along the centre ‘equator’ of the cell. Spindle fibres attached to each homologous pair to contract to separate the homologous chromosomes.
4
Q
What happens during anaphase 1?
A
The homologous chromosomes separate one to each end ‘pole’ of the cell.
5
Q
What happens during telephone 1?
A
Two new cells form each with a different combination of alleles as a result of independent assortment.
