So we're looking at populations and how does it affect them if they have the asexual approach to breeding and increasing their numbers versus a sexual approach where you have to have mating between two distinct and unique individuals.
00:21
Well asexual is a very easy one because everyone is the same.
00:29
We often will use the term cloning when we look at asexual reproduction because you have one individual, usually a single -celled organism, that will simply replicate itself.
00:46
It will go through mitosis and meiosis one and it's just boom a new one, right? or meiosis two, things like that.
00:56
It's just going to be all the same.
00:58
So unless there is a genetic mutation, there will be no genetic variance and that's a really big thing when you look at the population as a whole.
01:20
Little to no genetic variance means that the population is going to be very slow to evolve.
01:35
So if you have a population that is utilizing asexual reproduction, you might only have one or two of the original organisms that have created this entire population.
01:46
So they are all the same unless there has been a genetic mutation in one individual and maybe they've passed it on, maybe they haven't.
01:54
So they're all pretty much the exact same which means that unless there are more genetic mutations, you are not going to change.
02:03
So you're not going to be able to also change and evolve as your environment changes.
02:09
So this is a very limiting thing to your population in terms of changing and adapting to your environment.
02:16
Versus if we look at sexual reproduction, everyone is unique.
02:25
Everyone has their own set of genes, especially if the organisms have a lot of chromosomes, you know a lot of different genes in their genome...
