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: http://www.amoebasisters.com/about-us.html 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/biology We take pride in our AWESOME community, and we welcome feedback and discussion.

Amoeba Sister I would personally like to thank you for the clarification on how sex-linked traits work and how to diagram them. This will definitely display positive effects on my Test tomorrow.

So upset I'm just discovering these videos. Only two weeks left of the semester, But so far the videos have helped extremely. Would love to see epistasis Punnett square video.

"The first inkling that sex chromosomes were unique from all other chromosomes came from experiments conducted by German biologist Hermann Henking in 1891… Henking saw that some wasp sperm cells had 12 chromosomes, while others had only 11. Moreover, while observing the stages of meiosis that formed these sperm cells, Henking noticed that the mysterious twelfth chromosome looked different from all the others. He thus named this chromosome the "X element," to represent its unknown nature. The Y chromosome was identified as a sex-determining chromosome by Nettie Stevens … during a study of the mealworm Tenebrio molitor … Stevens proposed that chromosomes always existed in pairs and that the Y chromosome was the pair of the X chromosome discovered in 1890 by Hermann Henking … Stevens named the chromosome "Y" simply to follow on from Henking's "X" alphabetically."

But can you explain why it is carried by females only and expressed in males only. Or my knowing is wrong?

I honestly love your videos, I'm a junior in my college career and I understand all these examples better than my teacher has explained them. Thank you all.
Tyler Myers (7 months ago)
I like how my college biology class costs somewhere in the ballpark of hundreds of dollars, I go to every single class, read the textbooks, review my lecture notes, and pay attention, but still don't pick up on topics like this. I come to this 6 minute video, learn for free, and have the topic down instantly...

I had an X chromosome before it was cool, too. They've gone all mainstream and it's basically ruined it ; )

HELP!!! What if the male has the hemophilia trait, while the female does not? Is a male offspring with hemophilia possible?
2 Minute Classroom (1 year ago)
Yes. Since it is a sex linked trait and attached to the X-chromosome, the male offspring can have hemophilia if the mother is a carrier and and passes that hemophilia X onto her son. A male will always get his X chromosome from his mother, along with any associated traits. Hope that helped.

I have a question: Is the inheritance of hemophilia a case of dominant, intermediate or codominant inheritance? Saludos!!
lilmiszmeh135 (1 year ago)
I believe inheritance is complete dominance. When you are homozygous or heterozygous dominant for the trait, only the dominant allele is expressed in both cases and you won't have hemophila. It is only when you are homozygous recessive that you will have hemophilia. Hope it helps!

Do you have a video on pedigree charts?

This channel always helps with my science u guys get a sub😄
ScienceFan1859 (1 year ago)
Why not follow the custom of Capitals for labeling Dominant? Capital N for Normal, little n for color-blindness, or hemophilia, or muscular dystrophy? Using Capital H for NOT hemophilia is unnecessarily confusing...Big Fan, btw!
Arabella Isabel (1 year ago)
ScienceFan1859 it's because hemophilia is sex-linked recessive
Helpful video. Good job. I shared this with my students.
