phases Flashcards
1
Q
interphase 1
A
chromosomes replicate, a chromosome consists of 2 identical sister chromatids
2
Q
prophase 1
A
chromosomes condense and come together in homologous pairs (synapsis)
crossing over for genetic variation
nuclear membrane dissolves
3
Q
metaphase 1
A
homologous pairs line up at the equator
4
Q
anaphase 1
A
spindle fibres pull homologous chromosomes to opposite ends of the cell
sister chromatids remain together
5
Q
telophase 1
A
cytokinesis
6
Q
prophase 2
A
chromosomes recondense
spindle fibres reform
7
Q
metaphase 2
A
chromosomes line up along the equator
8
Q
anaphase 2
A
spindle fibres pull and separate sister chromatids to opposite ends of the cell
9
Q
telophase 2
A
nuclear membrane reforms
cytokinesis
4 unique daughter cells with haploid number of unreplicated chromosomes
