Part 6: Mutations Factors such as mutagens that enter the environment via industrial waste can affect one allele more than another if a population is exposed to the mutagen. As a result, the mutation may have different effects on individuals with different phenotypes. I’m not giving you specific directions here, but play around with mutation rates, pairing that with small population sizes and … Huntington’s 1. Bigger picture: Are mutations random or intentional? Are mutations good or bad? Do mutations increase, decrease, or randomly influence the fit between an organism and its environment? 2.

Step 1

This creates a scenario where the population is small, allowing us to observe the effects of limited genetic diversity and increased genetic drift. Show more…

00:01 First question is asking about the impact of small population on allele frequency.

00:11 This is based on the concept of genetic drift.

00:18 Some of the key features of genetic drift are as follows.

00:22 It is a random as well as directionless change in allele frequency.

00:29 The process of genetic drift occurs in small population.

00:35 Also the change occurs from generation to generation.

00:42 The process of genetic drift results to the formation of new species.

00:49 It also leads to loss of genetic drift.

00:51 Due to genetic drift, the harmful allelees may get fixed in the population concerned.

01:05 So from the given information, it can be concluded that in a small population there occurs genetic drift which further leads to changes in allele frequency.

01:22 The second question is asking about the effect of migration on evolution.

01:29 So the process of migration increases variability within a population and it occurs because the process of migration changes the gene frequency of the population.

01:42 And this can occur either by bringing in more copies of the same gene, or it can also occur by bringing in a new allele that has arisen by mutation.

02:01 And also because of variation within a population, this leads to the survival of individuals, even if the environment changes drastically.

02:13 And this suggests that the individuals gets evolved in the new environment.

02:19 So this is how migration leads to evolution in a particular population.

02:22 The third question is asking about mutations...
