When artificial selection is practiced over many generations, it iscommon for the trait to reach a plateau in which further selectionhas little effect on the outcome of the trait. This phenomenon isillustrated as shown. Explain why it occurs.
From a biological viewpoint, speculate as to why many traits seemto fit a normal distribution. Students with a strong background inmath and statistics may want to explain how a normal distributionis generated, and what it means. Can you think of biological examplesthat do not fit a normal distribution?
Sexual selection occurs whena. one sex has a higher fitness than the otherb. a species exhibits sexual dimorphismc. there is a male dominance hierarchy and only the alpha male reproduces. d. There is monogamous mating.e. A trait is favored by one sex such that individuals of the opposite sex possessing that trait have an increased likelihood of reproducing.
Which statement/s can best explain how evolutionary perspective help us understand senescence? (a) Evolutionary theory allows scientists to compare closely related species that differ inhow they invest in reproduction and in body maintenance, to test for effects on the agingprocess. (b) Understanding evolution can generate predictions about how individuals with certain suites of life-history characteristics might fare in the aging process when compared to other individuals without those characteristics. (c) Because aging is a natural process for all species, explaining its evolution through natural selection is insufficient. (d) Evolutionary studies provides insight into the historical development of adaptations, such as the number of offspring an individual has, that may contribute to life-history trade-offs, such as aging. A. Three of the 4 statements are correct. B. (a) and (d) C. (a) only D. (b) and (c)
Pick any trait you like in any species of wild plant or animal. Thetrait must somehow vary among different members of the speciesNote: When picking a trait to answer this question, do not pick the trait of wing color in butterflies.A. Discuss all of the background information that you alreadyhave (from personal observations) regarding this trait.B. Propose a hypothesis that would explain the genetic variationwithin the species. For example, in the case of the butterflies,your hypothesis might be that the dark butterflies survive betterin dark forests and the light butterflies survive better in sunlitfields.C. Describe the experimental steps you would follow to test yourhypothesis.D. Describe the possible data you might collect.E. Interpret your data.
In domesticated dogs, size has a high heritability, andthe trait is determined by only a small number ofgenes. In contrast, genetic variation at more than180 QTLs explains only a very small proportion ofthe high heritability for height in humans. What couldexplain the missing heritability in humans, and howcould you test your hypothesized explanations?
The genetic variability of the Giddings children started out asmutations that occurred thousands of years ago. Take haircolor: Our distant ancestors probably all had dark hair, its colorcontrolled by multiple genes located on several different chromosomes.The alleles that produced Tess’s blond hair originatedas mutations in genes that control the amount and type of hairpigment. Tess probably inherited only “pale hair” alleles of all ofthese genes, so for any given hair color gene, she has the samepale hair allele on both homologous chromosomes. Chris, on theother hand, inherited both dark and pale hair alleles for at leastsome of the genes, so his homologues have different alleles. Aswe will see in Chapter 11, in many cases one allele (in this case,the dark hair allele) overrides the effects of the other allele (thepale hair allele), so Chris has black hair. What combinations ofalleles might have been packaged in Tess’s eggs and Chris’ssperm, which would combine to produce their…
Suppose an individual organism aids the survival andreproductive success of the offspring of its sibling. Howmight this behavior result in indirect selection for certaingenes carried by that individual?
In March 2013, the American Journal of HumanGenetics published a report that an AfricanAmerican man who submitted his genome forcommercial genealogical analysis had a Y chromosome whose sequence was very different from thatof other Y chromosomes that had been characterized previously. The investigators then found thatcertain males among the Mbo (an ethnic group inCameroon) shared many of the polymorphisms firstfound in this African-American man. How do youthink these findings would have altered estimates ofwhen a man carrying the MRCA for the human Ychromosome would have lived on the earth?
Ancestry prediction in 23 & Me is continuously updated as new individuals aregenotyped. This can change an individual’s personal predicted ancestry by refining theregion of ancestral origins or potentially identifying a less common ancestry in the lineage.This can similarly happen with animals where new breeds are identified in an individual’sancestry as new breeds are genotyped. Explain how ancestry prediction is done and howthat prediction can change as more individuals are genotyped.
