Question:- Consider selection on two traits. The selection gradient on trait 1 is -0.2, and the selection gradient on trait 2 is 0.25. The additive genetic variance of traits 1 and 2 is 0.53 and 0.42, respectively, and they have a genetic covariance of 0.2. Round all answers to 3 decimal places. a) What will be the predicted evolution response of each trait? b) What would the predicted evolutionary response be if the covariance was 0? c) How does the genetic covariance between the traits influence evolution?
Question:- Changes in environmental conditions can render previous adaptations as maladaptations. Describe an example of maladaptation in humans during the last 100,000 years. Your answer should include a discussion of the relevant environmental factors, fitness (in both environments), and specific variants (genotypes). Please explain and other useful info. Thanks
Question- How is genetic drift different from natural selection? choose one from below 1. Natural selection occurs because some alleles confer higher fitness, whereas genetic drift occurs because of sampling error 2. natural selection has a stronger effect in large populations, whereas genetic drift acts primarily in small populations 3. natural selection is a mechanisms of evolution, whereas genetic drift is not a mechanisms but an outcome of evolution 4. natural selection tends to cause very rapid evolution, whereas genetic drift tends to operate on much longer time scales.
Heritability is valid for (select all that apply)? a-No answer text provided. b-No answer text provided. c-Multiple populations of a species d-Single populations of a species e-Any environment f-Any point in time g-A specific point in time
INSTRUCTION: - Do not copy in Google or here in Bartleby - Answer the question properly. INTRODUCTION: Human immunodeficiency virus entered human populations after evolving from a simian immunodeficiency virus. Nikolaas Tinbergen (1963), proposed explaining shifts in traits from two perspectives: dynamic versus static, and proximate versus ultimate. This framework can be used to understand the evolution of a trait in four ways: (i) causation (proximate/static): the mechanism of the trait as it works in the present; (ii) survival value (ultimate/static): how function of the trait enhances survival or reproduction; (iii) ontogeny (proximate/dynamic): the development of the trait in an individual; and (iv) evolution (ultimate/dynamic): the phylogenetic history of the trait. QUESTION: "Use these categories (i-iv) to discuss the causes for the virus shifting to humans from other primates." In these cases you will try to explain how the virus shifted to a new host on the basis of (1)…
Follow up on Question 2. The purpose of including species D in the phylogenetic reconstruction is so that it can be used as a. an in-group for inferring the polarity of trait evolution b. an out-group for inferring the polarity of trait evolution c. an ancestral group for inferring the polarity of trait evolution d. a monophyletic group for classifying vge gene types e. None of the above

Choose correct option do explain. 1.Two closely-related finch species occasionally form hybrids. These hybrids tend to have beaks of an intermediate size to their parental species, which have large and small beaks respectively. What evidence would suggest there is extrinsic postmating isolation? Group of answer choices- a.The hybrids are not able to obtain enough food due to beak size b.The hybrids die early due to deleterious gene combinations c.The hybrids cannot reproduce with members of either parent species d.The hybrids cannot reproduce with other hybrids
One of the findings from Strickland et al. 2019, was that certain color morphs among Chelymorpha alternans beetles are more common at some field sites than they are at other sites. Strickland and colleagues used cross breeding experiments to investigate these patterns and found evidence that color variation was mainly due to Mendelian inheritance. In other species, geographic variation in coloration might not be due to Mendelian genetics. (a) What is another possible explanation for geographic variation in coloration? (b) What sort of experiment could you use to test this alternative explanation?
