• Selection coefficient ~ • Can use equation to estimate what mutation rate would be needed to counter s = , and give q^ of • And the calculated answer is X mutations per allele per generation • Wirth et al. directly measured rate of X • Mutation-selection balance. · Mutations with even a small selective advantage can lead to rapid evolution of populations. This animation uses equations from population genetics to simulate how quickly a new, advantageous fur color spreads through a rock pocket mouse population. The selective advantage discussed in the animation corresponds to the selection coefficient (s). Students apply the criteria from the Natural Selection Checklist to another example. Small groups or individuals complete a short reading and a minor graphing exercise. Then they use the information to fill in the Natural Selection Checklist to determine whether or not the example is indeed the result of natural selection, then report out.
When selection favoring the production of vitamin D is stronger, gene versions that produce less melanin and lighter skin become more common. When selection against UV damage is stronger, gene versions producing more melanin and darker skin become more common. Which form of natural selection wins out is broadly influenced by geography. Natural Selection: a natural process that results in the survival and reproductive success of individuals or groups bestadjusted to their environment and that leads to the perpetuation of genetic qualities best suited to that particular environment 10 Examples of Natural Selection Unit 6: Evolution Article written by Diana Bocco Defined. Discover natural selection as a mechanism of evolution with the Amoeba Sisters. This video also uncovers the relationship of natural selection and antibiotic.
Allele frequency. Just as a reminder, an allele is a variant of a gene. You get a variant of a gene from your mother, and you get another variant of the gene from the father. So, when we're talking about the allele, we're talking about that specific variant that you got from your mother or your father. We've seen this before, but now let's dig. Natural Selection book.
