After learning about mitosis and meiosis from our individual videos, explore the stages side by side in this split screen video by The Amoeba Sisters! Expand video details for table of contents. Vocabulary in this video includes chromosome, chromatid, haploid, diploid, crossing over, and homologous chromosomes.

0:50 Intro to Mitosis/Meiosis
1:07 Starting Cells in Mitosis/Meiosis
1:20 Interphase (happens before mitosis and meiosis)
2:19 Mitosis/Meiosis I Split Screen
4:30 End of Mitosis
4:46 Meiosis II

Hope you enjoy our comparison! You can see our individual videos on mitosis https://youtu.be/f-ldPgEfAHI and meiosis https://youtu.be/VzDMG7ke69g We also like to pin extra points/clarifications here. Crossing over in meiosis has a major role in genetically diverse offspring; however, Pinky learned in one of her graduate courses that mitosis crossing over- while very rare (likely why it's uncommon to see it in intro bio courses)- can occur. It can have a role in human cancer and "loss of heterozygosity." While this unusual event is not discussed in this intro video, here is a further reading suggestion where you can learn more about it: https://www.ncbi.nlm.nih.gov/pmc/arti... .

The Amoeba Sisters videos demystify science with humor and relevance. The videos center on Pinky's certification and experience in teaching science at the high school level. Pinky's teacher certification is in grades 4-8 science and 8-12 composite science (encompassing biology, chemistry, and physics). Amoeba Sisters videos only cover concepts that Pinky is certified to teach, and they focus on her specialty: secondary life science. For more information about The Amoeba Sisters, visit:

We cover the basics in biology concepts at the secondary level. If you are looking to discover more about biology and go into depth beyond these basics, our recommended reference is the FREE, peer reviewed, open source OpenStax biology textbook: https://openstax.org/details/books/bi...
