Genotype and environment interact to produce the phenotype ofan animal. Explain comprehensively the types of mechanisms bywhich this interaction takes place.
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)
The A and B antigens in humans may be found in water-soluble form in secretions,including saliva, of some individuals (Se/Se and Se/se) but not in others (se/se). The populationthus contains “secretors” and “nonsecretors.”(a) Determine the proportion of various phenotypes (blood type and ability to secrete) in matingsbetween individuals that are blood type AB and type O, both of whom are Se/se.(b) How will the results of such matings change if both parents are heterozygous for the genecontrolling the synthesis of the H substance (Hh)?
Morphogens play a key role in development, cre-ating concentration gradients that inform cells of wherethey are and how to behave. Examine the simple patternsrepresented by the flags in Figure Q21–1. Which do yousuppose could be created by a gradient of a single mor-phogen? Which would require gradients of two morpho-gens? Assuming that such patterns were present in a sheetof cells, explain how they could be created by morphogens.
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.
. The upper forelimbs of humans and bats have fairly similarskeletal structures, whereas the corresponding bones inwhales have very different shapes and proportions. However,genetic data suggest that all three kinds of organisms divergedfrom a common ancestor at about the same time. Which ofthe following is the most likely explanation for these data?(A) Forelimb evolution was adaptive in people and bats, butnot in whales.(B) Natural selection in an aquatic environment resulted insignificant changes to whale forelimb anatomy.(C) Genes mutate faster in whales than in humans or bats.(D) Whales are not properly classified as mammals.
