Epistasis!

Following on from simple monohybrid crosses to the brilliant epistasis - believe it or not, one of the simplest multiple gene interactions!

Thanks Hermione!

[@jmauchley1715]

a late night study session before a test can always be made a little better with a cool British voice girl that's good at explaining stuff. Thanks!

[@jakobjaworski9526]

Eight years later, exactly the kind of explanation I was hoping to find. Thank you!

[@vicentekendrick9585]

This is the only video that clarified me on epistasis. Thanks

[@gg3675]

Six years later and you're saving my life, thank you!

[@xxsuggiexx]

This is the best video on epistatis I've seen so far on KZbin. Very clear and concise. Was having trouble learning it just now, but this video helped lots. Thank you so much!

[@spulwasser]

Although I'm not a native speaker, I think this video has a lot of input and you spoke very clearly. Before watching, I only had a short text explaining one gene is preventing the other from being expressed. Now I understand what was meant with that! Thx

[@Brad96]

Genuinely the best epistasis video on youtube, thank you very much! F215 is my last exam so id totally forgotten how epistasis worked

[@leoescamilla5497]

Quite low tech but very well explained, even after 8 years

[@MrMouzaki]

thanks so much i study gentics with frensh language so i was searching for frensh tutorials but even if i'm not too godd in englsih i did understand your's easily it was simple and easy thanks again

[@arnathorarensen7356]

Oh my god, thank you! This made so much more sense to me

[@Janice99]

Thank you soooooo much!! I was so confused until I saw your video.

[@florencewallace544]

Thank-you SO much I have searched everywhere- in textbooks/ other videos/ etc etc and none had 100% sorted my confusion out, your explanation somehow has- so thank-you :)

[@aryaa3998]

Thank you, very well explained.

[@sportster832]

Great job of explaining! I understand much better now

[@_sacapuntas_8612]

Thank you so much!:)

[@damnnn3790]

thanks girl you saved my life

[@jeffreyaparker3462]

Very well explained for me thank you!

[@suzan6254]

nice video! this helped me study for my exams

[@sundusm2507]

You such a good teacher

[@RodesLaw]

thank you.

[@YoyoBear12]

Thank you! I get this now!!! and omg I love your accent btw

[@emmylou547]

great explanation!

[@glitch2.087]

Aa I think I'm in love with ur voice

[@joshuaganness8785]

thank you so much, this was really helpful!

[@melissadauzonne9944]

very very helpful thanks!

[@legenarymaster3696]

Thanks :)

[@taeyang]

your accent is amazing

[@hm2OO5]

Thanks!

[@missdogirl]

Thank you! :D

[@Tinuviel-gv4xm]

you have a very cute voice. you go girl!!!

[@saramurtaza7777]

You sound so much like emma watson lol

[@damnnn3790]

what a queen

[@justinb2391]

I was gonna say that you have a sexy voice, but I've been beaten to it. Thank you for the Epistasis explanation though!

[@Yeeeeeehaw]

Nice voice!!! 😍

[@JKHero]

So, how about giving us examples of real critters with these gene interactions ?

[@scienceclub3806]

JKHero what do you mean by real critters? Here is a really good article that has some real life examples: www.nature.com/scitable/topicpage/epistasis-gene-interaction-and-phenotype-effects-460 I hope that helps :)

[@JKHero]

Yes, that link helps. Your vid seemed to be all theory with no examples. Have you considered including how the gene for brindle affects the red and black genes in cattle?

[@scienceclub3806]

JKHero it is mostly theory but there are real life examples of the colour scenarios (such as peas) - I think it's better to understand the mechanisms rather than memorise examples. There are loads of different mechanisms and epistasis is the most simple of multiple gene interactions.

[@JKHero]

I did NOT suggest that a person "memorize examples." Where did you get such an idea? Examples are useful to give the theory relevance, to connect it to life. People know that squash can be white, yellow, or green. Using it as an example of epistasis explains part of life and makes the information meaningful. Understanding how the gene for brindle in cattle switches the gene for black from dominant over red to co-dominant with red is useful. Examples are NOT something to be memorized. They are something that enhances understanding, that gives a reason to learn genetics.

[@scienceclub3806]

JKHero I totally agree - and personally I love learning about the real life applications of genetics. I made the video quite a while ago to support the A-level biology syllabus as I used to get lots of questions about the topic. It would probably be better with some real-life examples but I hope the explanations have still helped people.

[@amalhamze1665]

Hi 🙂

[@abdobedo9428]

I knew there would be such comments before I see them. xD

[@jumanasamy8966]

Wtf is the music

[@scienceclub3806]

I actually have no idea myself - I made the video so long ago!

[@jlpetty85]

Found the hands distracting and the explanation still rather confusing....

[@scienceclub3806]

Sorry you found it confusing - I move my hands a lot when I talk and try to explain things, and that means when I speed it up they move very quickly! No one's perfect.

[@colbymchenry]

Try to concentrate, really really hard. You'll get it.

[@EEKProductions]

you're good youre fine love the video not confusing and ur hands arent distracting its helpful
