What Do Pea Plants Have To Do With Your Eye Color? (Mendelian Genetics): Crash Course Botany #10

Рет қаралды 69,246

Күн бұрын

All of the different plants on Earth have come about thanks to the simple rules of genetic inheritance, which determine how traits are passed on from one generation to the next. In this episode of Crash Course Botany, we’ll explore the remarkable story of Gregor Mendel, a botanist and mathematician who laid the groundwork for modern genetics with little more than some peas and a paintbrush.

Phenotype & Genotype 4:40
Mendel's Principles of Inheritance 5:38
Effects of Mendel's Research 9:14

The answer to the extra credit question is…. Hawkweed! What's a cool discovery you know about that is often overshadowed by a scientist's more famous work?

This is one of my favorite video series on KZfaq. Alexis is teaching important science concepts, and she is also presenting a master class on how to make the learning process fun and engaging. Thanks Alexis!

Omg, SO excited to see Alexis on here! I am trying my hand at hybridizing flowers so I thought "that's right up my alley" when I see the video title. To immediately see Alexis on my screen is SUCH a delight. I live in Cbus and she has been so kind and friendly whenever I or my friends have seen her out and about and said hello. So happy to see you succeeding and sharing your passion and knowledge with the world 💪👍❤️

Contemporary popular expositions have been trying to get _away from Mendelian_ presentations, because it is clear that so much of life is multigenic, and that expression is complex. Indeed, human eye color is a good example of this need to do more than Mendelian genetics. If one takes a direct to consumer DNA test, such as from 23andMe, there are "predictions" of eye color but they are usually *heavily caveated* because the actual eye color expressed is not a simple Mendelian trait.

genetics are so interesting! makes me want to do my own peapod experiments, too bad I have the opposite of green thumb 😅

@Chira92 10 ай бұрын

This is so interesting. My mother has two butterfly bushes with different coloured flowers. Now I'm curious which colour is the dominant one and willing to find out with my own knowledge of genetics 😊.

@medusianAllure 11 ай бұрын

Thank you for explaining the answer my high school biology teacher couldn’t answer 15 years ago. I'm looking forward to learning more about complex alleles. The example I gave was my eye colour. I have hazel eyes, but my dad has blue eyes (recessive) and my mother had brown eyes. I have my paternal grandpa's eyes despite blue eyes' recessiveness. Or how my hair texture is a combination of both parents and I keep on finding stray red and blonde hairs despite them being once again, recessive alleles from my paternal grandpa. Or lastly, my physical mutation that I inherited from my dad that never existed in living memory.
