Genetic Evolution

Sexual reproduction produces distinct population variations. Heredity determines the traits and qualities to be passed down to the progeny. Over time, this variation within-species is also affected by the process of human evolution. The study of how genetic variation leads to evolutionary changes is known as genetic evolution. If a trait helps an organism to survive and reproduce, it is more likely to be passed down the generations. It is rare that such traits result in a completely distinct set of traits in descendants than the ancestral population; this can result in the emergence of a new species.

Two populations of snakes are separated by a river. The snakescross the river only on rare occasions. The snakes in the two populationslook very similar to each other, except that the members ofthe population on the eastern bank of the river have a yellow spoton the top of their head, whereas the members of the western populationhave an orange spot on the top of their head. Discuss twoexperimental methods that you might use to determine whether thetwo populations are members of the same species or members ofdifferent ones.

Natural selection tends to work toward genetic unity;the genotypes that are most fit produce the mostoffspring and increase the frequency of adaptive allelesin the population. Yet there remains a great deal ofvariability within the populations of species. Describethe factors that contribute to this genetic variability. Provide the link of references
Which of the following statements describes an example of genetic drift?a. Allele g for fat production increases in a small population because birds with more bodyfat have higher survivorship in a harsh winter.b. Random mutation increases the frequency of allele A in one population but not inanother.c. Allele R reaches a frequency of 1.0 because individuals with genotype rr are sterile.d. Allele m is lost when a virus kills all but a few individuals and just by chance, none ofthe survivors possess allele m.

Eugene Eisen selected for increased 12-day litter weight (total weight of a litter of offspring 12 days after birth) in a population of mice (E. J. Eisen. 1972. Genetics 72:129–142). The 12-day litter weight of the population steadily increased, but then leveled off after about 17 generations. At generation 17, Eisen took one family of mice from the selected population and reversed the selection procedure: in this group, he selected for decreased 12-day litter weight. This group immediately responded to the reversed selection: the 12-day litter weight dropped 4.8 g within 1 generation and dropped 7.3 g after 5 generations. On the basis of the results of the reverse selection, what is the most likely explanation for the leveling off of 12-day litter weight in the original population?
Three basic predictions underlie genetic drift in populations: (1) As long as the population size is finite,some level of genetic drift will occur; thus, withoutnew mutations, all variation will drift either to fixationor to loss. (2) Drift happens faster in small populationsthan in large populations. (3) The probability that anallele is fixed (goes to a frequency of 1.0) is equal toits initial frequency (p) in the population, while itsprobability of loss from the population due to drift isequal to 1 − p. Given these three predictions:a. What is the allele frequency of a new autosomalmutation immediately after it occurs in a diploidpopulation of size N = 100,000?b. What is the allele frequency of a new autosomalmutation immediately after it occurs in a diploidpopulation of size N = 10?c. In which population does the new mutation have ahigher probability of going to fixation by chancewith genetic drift?
Consider the first copy of an allele for insecticideresistance that arises by mutation in a populationof insects exposed to an insecticide. Is this mutation an adaptation? If, after some generations,we find that most of the population is resistant,is the resistance an adaptation? If we discovergenetic variation for insecticide resistance in apopulation that has had no experience of insecticides, is the variation an adaptation? If an insectpopulation is polymorphic for two alleles, eachof which confers resistance against one of twopesticides that are alternately applied, is thevariation an adaptation? Or is each of the tworesistance traits an adaptation?
Godfrey Hardy and Wilhelm Weinberg stated the principle of equilibrium to describe the genetic makeup of a population. The theory, also known as the Hardy-Weinberg principle of equilibrium, states that a population’s allele and genotype frequencies are inherently stable.
