Meiosis
-
Interphase
-
-
during DNA replication (S)
each chromosome replicated
to produce 2 identical copies,
SISTER CHROMATIDS
Purpose
produce
gametes
-
haploid gametes ensure that when
male + female gametes fuse, normal
diploid no. restored
gametes formed from diploid cells
and contain only 1 chromosome from
each homologous pair in the parent
cell
-
Meiosis I
Prophase I
chromatin condenses,
chromosomes visible
Each chromosome consists
pair pf sister chromatids, joined
by centromere
-
-
-
-
Metaphase I
-
orientation of chromosomes
towards pole is random +
each pair behaves independently
of every other pair
-
-
-
-
Cytokinesis
cells now haploid - only contain 1 member
of each orig homologous pair
still same amount DNA as parent cell
