Your cells are dividing inside of you all the time. Check out this educational learning song about meiosis and how cell division works. To be used by students for studying or by teachers as a supplemental classroom resource.

Do you know the difference between meiosis and mitosis? At the most basic level, meiosis has two cell divisions while mitosis only has one. Meiosis, used in sex cells, creates cells that are NOT genetically identical to the parent, allowing for genetic variation. In mitosis, used in somatic cells like your skin or blood, creates cells that ARE 100% identical to their parent. Learn more about mitosis here.

Lyrics:

VERSE 1:
A special cell division
for sexual reproduction
Meiosis happens to
an entire organism to reproduce

With two cell divisions, the
Daughter cells vary genetically
Four daughter cells made when finished
created from a single parent

They’re new daughter cells, although
Each one has half the chromosomes
Haploid, half the chromosomes only
produce sex cells we call gametes

The first part is Meiosis I
Homologous chromosomes split up
Prophase chromosomes x-shaped structures
Two sister chromatids, identical

Copies pair up together
Exchange bits of DNA
A process called recombination
also crossing over

Metaphase, pairs line up next
and gather into the center
Opposite poles, centrioles
Meiotic spindles, then

Anaphase I, chromosomes are pulled
Apart to opposite spindle poles
Telophase and cytokinesis
Each pole, has set of chromosomes gathering
Membrane forms, creates nuclei
23 chromosomes each, completed divide

CHORUS:
Two times, cells divide
half the chromosomes, they’re called haploid
Four new cells are constructed
In sex cells, it’s Meiosis

Two times, cells divide
half the chromosomes, they’re called haploid
Pro, Meta, Ana, Telophase
Pro, Meta, Ana, Telophase

Two times, cells divide
half the chromosomes, they’re called haploid
Four new cells are constructed
In sex cells, it’s Meiosis

Two times, cells divide
half the chromosomes, they’re called haploid
Pro, Meta, Ana, Telophase
Pro, Meta, Ana, Telophase

VERSE 2:
Meiosis one’s finished
Two daughter cells, and each with
23 chromosomes
Ready to split once more so

Meiosis two begins
Both cells divide again
Interkinesis arranged
Prophase, chromosomes x-shaped

Metaphase, chromatids are lined up
Anaphase, move apart to the opposite
Telophase, then cytokinesis
Four new cells, it’s meiosis

CHORUS:
Two times, cells divide
half the chromosomes, they’re called haploid
Four new cells are constructed
In sex cells, it’s Meiosis

Two times, cells divide
half the chromosomes, they’re called haploid
Pro, Meta, Ana, Telophase
Pro, Meta, Ana, Telophase

Two times, cells divide
half the chromosomes, they’re called haploid
Four new cells are constructed
In sex cells, it’s Meiosis

Two times, cells divide
half the chromosomes, they’re called haploid
Pro, Meta, Ana, Telophase
Pro, Meta, Ana, Telophase
