Cell Cycle
Interphase
Stage 1
Replication- Synthesis of
DNA
Parent Cell
Stage 2
DNA forms into
Chromosomes
containing
genes
alleles
Cell Division
Asexually
Second type
mitosis
where
Somatic cells
undergoes stages
prophase
metaphase
anaphase
telophase
First Type
binary fusion
Sexually
Third type
meiosis
where
germ cells
in
testes and ovaries
undergoes process to create
gemetes
germ cells undergoes
interphase
stage of meiosis
prophase 1
homologuos chromosomes
pair up from tetrade and
crossing over
occurs resulting in
genetic variation
independent assortment
metaphase 1
nondisjunction
can occur inthis stage resulting in
disorders
anaphase 1
telophase 1
cytokenisis
splits the cell into two
daughter cells
meiosis begins
prophase II
metaphase II
anaphase II
nondisjunction
can occur in this stage, resulting in
disorders
telophase II
cytokinesis
meiosis is complete and the four
daughter cells
are called
haploid
when combined with another gemete
zygote
forms
germ cell are called
diploid
