Among the most prevalent pathologies that afflicthuman beings is heart disease, which can have a severeimpact on quality of life and can even result in prematuredeath. While heart disease mostly afflicts those who areolder, 1% or 2% of people in their 30s, and even in their20s, suffer from this disease. Genetic and environmentalcomponents of this disease exist. What strategy mightyou use to choose families to participate in a GWAS ofheart disease–causing genes? Explain your reasoning.
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
The elaborate tail of the peacock (Pavo cristatus) is approximately 120 cm to 150 cm long, while the tail ofthe peahen is quite short. The long tail reduces the male bird’s ability to maneuver and fly and makes him moreconspicuous to predators. Suggest at least one reason why this cumbersome structure has not been eliminatedby natural selection.
What describes the phenotypic plasticity of an organism best? O the degree of which individuals can change over time by altering their genotype O the effect of variable environment on the genotype of an organism O the variation of the target phenotype for a given genotype in different environments O the change of a phenotype due to ingestion of detrimental plastic material (as for instance plastic straws by sea turtles). O the degree of which a given genotype is adapted to a particular environment
The ratio of nonsynonymous differences pernonsynonymous site, dN, to synonymous differences per synonymous site, dS, can be usedto test for positive selection Imagine that in a duplicate pair of loci, oneparalog is evolving neutrally while the other isevolving under strong positive selection. Whatspecific data are needed to detect that situationusing the dN/dS ratio, and what pattern do youexpect to see?
Ancient societies used knowledge that traits are heritable in domesticating animals and developing agricultural crops. What might account for the failure to recognize that the same processes operate in humans?
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?
EVOLUTION CONNECTION Ethical considerations aside, ifDNA-based technologies became widely used, discuss how theymight change the way evolution proceeds, as compared withthe natural evolutionary mechanisms that have operated forthe past 4 billion years.
