Sexual and asexual reproduction. Mathematical models

What is the advantage of sexual reproduction over asexual?
Simple models show the benefits of sexual reproduction.
It is worth noting that most organisms that do not have sexual reproduction use other ways of exchanging genes.

I love how this is just an intro to genetics.

[Fcalysson]

I never understood the advantages of sexual reproduction until this video

[gryphonschnitzel]

great visual representation of these abstract concepts !

[gryphonschnitzel]

16:40 love how you used cursed sounds off hell and suffering to profile the harmfull mutations taking over

[Froxyze]

This is a very good made video, even for people who don't understand math, it was very entertaining.
Btw, what was that ending😂😂

[thomquiri]

19:07 thought this was going elsewhere for a moment lmao

[thomquiri]

15:25 so that's why you don't do incest... Gotta keep the population as big as possible

[derrickthewhite]

19:45 really glad he said this, because I was thinking it the whole time. asexual organisms CAN share genes... though its a lot less thorough.

[somnvm]

amazing video as always, visualisations are fun 👍

also there is a little typo [it's supposed to be genomE]

Great video! Love your deep dives!
Would've liked to see some variations on pure asexual and sexual reproduction:
Loads of organism irl will employ hybrid strategies, capable of both, and preferring either depending on circumstances. And Fungi are completely *wild* with some species having absurdly off the charts far more sexes than mere two.
It's also very interesting just how important population size and selection pressure are. And by your globally randomized two offspring per parent method, you eliminated a lot of other factors that would play a big role irl:
For one, stuff would have to work locally, both in terms of literal physical proximity (well, to a point. Obviously there are loads of strategies that mitigate this. Looking at you, spores), and in terms of the pieces need to fit together to result in offspring that themselves remain capable of reproducing.
For another, if it's a more or less cooperative act between two+ organisms, you'd naturally get coevolution dynamics and sexual selection, which leads to all sorts of weird and interesting outcomes that go completely unexplored by this simple simulation.
Nevertheless, excellent work! The most interesting aspect imo is how much more effective sexual selection apparently ends up being in particularly low-pressure mutations. Presumably that translates to far weaker signals having a proper chance to persist, and thus to allow far more gradual evolutionary steps, exploring the fitness landscape in a much more fine-grained manner than clones ever could.

great video i finally understand this... what if there was 3 or more... like u need 3 parents for each offspring wouldn't this be even better than 2?

[Wisald]

Huh, I didn't see this video in my feed when it dropped, had to go to your channel directly after seeing new video, weird.

[LostLargeCats]

It's surprising how beneficial sexual reproduction is, especially with large populations. Or alternatively, how beneficial it is to have large intermixed populations to maintain a healthy species.

[Lizo]

Your videos are fun and easy for me to understand these biological facts, keep on going!

[TheAgamemnon]

That is a nice base. Please follow it up with an introduction to information retention, dominant/recessive alleles and chromosome crossover.

[oystercatcher]

Absolutely brilliant explanation and visuals! Never have I understood the pros and cons so clearly. I to a grappling with how to do sexual reproduction in a simulation with a compatible genome. I feel some kind of Gene Regulation Network allowing duplicate ‘genes’ and soft input/outputs much like protein specifity might be required

[Pauline-kd]

I wouldn't have used the best organism to represent the species with sexual reproduction because it makes the species look better than it is since all the less lucky combinations were ignored

[beaub]

Please upload more i love your channel

[Elearen]

Come on babe, it’s for the future of the population

[kostas_ts]

Very nice visualisation to explain these concepts. Even though i am quite familiar with them, it renewed my understanding. My favorite way of reproduction is definitely sexual 🤣
