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

Divided into two stages
