Genetics

[@BrownLikeBrownie]

Sir your videos are extremely helpful, hope you haven't stopped making videos and continue n the rest of A2 Bio and Chem Much regards -A2 student

[@jeremey4321]

Is that why all ur vids are black and white?

[@pariss4957]

Thank youuu! I found that story about you having colour blindness really put sex linkage into context and helped me understand it :)

[@ganganaperera9405]

In 2020?

[@aliyahbibi3748]

you made a mistake while talking about the sex linkage tree 12.50

[@courtneylouisehalls]

Hello, can you give me a quick definition of carrier as you missed it out & I prefer your definitions as they are easy to remember? Thank you!

[@pariss4957]

What would you say the best way for revising this topic is? Should I practice lots of questions and learn the definitions?

[@EpicEditsBySaz]

You've saved me ;( (happy crying lol).

[@afridi95]

@MrBioTom1 hey, can you please do a video for the gene technology and probing section. I find that section the most difficult in a level biology.

[@MrBioTom1]

I will :) I will definitely do all A level Biology videos and most A2 chemistry ones. Generally if a video isn't up its because I have learnt the material yet :)

[@RyuFan1999]

*haven't

[@RyuFan1999]

loll

[@hashimmohd2838]

Nice

[@samueldarling8800]

thank you very much these videos are great, only advice is that i feel like some of it is quite rushed, i know you dont want the videos being longer but if you could slow down and when explaining things with scientific terms use the simpler terms (or explain the scientific ones each time) it would be clearer and easier to learn the topic. thanks

[@SammieAli1]

Everything was going so well, until you mentioned Chi-squared 😭😭

[@Madhattress6]

Thank you, you've really helped me understand this :) Hope you get/got all the grades you deserved Tom :) x

[@kirstenrichardson1739]

You have honestly helped me out so much, keep up the good work! :)

[@davidsmith-rl3jz]

Please make more videos

[@hamayonfaisal829]

How do you know that one of those two genes is epistasis to another?

[@MrBioTom1]

Hamayon Faisal If you do a dihybrid cross and you don't get a 9:3:3:1 ratio in the phenotypes it is usually down to epistasis :)

[@Newcakee]

I don't suppose you'd be able to do a video on electrochemistry please?

[@anjalirawat9941]

Does the critical value change for different questions or stay the same?

[@elliotverry730]

Thanks so much for these videos, so greatful

[@sineadryan4424]

I'm writing an essay about responses and I found myself saying 'its important for the bacteria to respond to the harsh conditions in order to survive and therefore replicate because...' and I don't know how to finish the sentence. It's the same when I talk about humans, why is it important that we survive and reproduce?

[@MrBioTom1]

Essentially it's not. To be a bit dark, survival and reproduction are pointless because you reproduce so that your offspring can reproduce so their offspring can reproduce and just that forever. In reality this is so the species can survive and you can pass on your genes to the next generation which is evolution's "definition" of "success". If you survive you reproduce, if you reproduce your genes are in the next generation, the more you reproduce the more your genes are a part of the population and therefore you have been successful. Life is pretty futile when you actually think about it, it's existing so your genes can exist more.

[@sineadryan4424]

MrBioTom1 thank you haha yeah it did get me thinking what is the point...Is it the same for viruses considering they're not actually living organisms?

[@MrBioTom1]

Yeah definitely, the only difference is that viruses use the host cells' machinery to do the replication rather than reproducing itself but essentially it's machines self-replicating so it can self-replicate some more.

[@sineadryan4424]

MrBioTom1 thank you very much for your help!

[@izzysparks3088]

Best explanation I’ve ever seen, thank you

[@MelanieTrees]

This is so helpful!!! Thank you so much :)

[@MrDonIlyas]

where is complimentary epistasis?

[@afridi95]

Great videos, is your name tom mclarean by any chance

[@MrBioTom1]

no, Munro :)

[@haloshoot3218]

thanks for the vid

[@tocalucky7380]

Nice video. Keep it up

[@alexbeyond7939]

👍

[@naveedhabib1869]

thank you soo much for the video.
