- Mr. Jones is a pig farmer. For many years, he has fed his pigs the food left over from the local university cafeteria, which is known to be low in protein, deficient in vitamins, and downright untasty. However, the food is free, and his pigs don’t complain. One day a salesman from a feed company visits Mr. Jones. The salesman claims that his company sells a new, high-protein, vitamin-enriched feed that enhances weight gain in pigs. Although the feed is expensive, the salesman claims that the increased weight gain of the pigs will more than pay for the cost of the feed, increasing Mr. Jones’s profit. Mr. Jones responds that he took a genetics class at the university and that he has conducted some genetic experiments on his pigs; specifically, he has calculated the narrow-sense heritability of weight gain for his pigs and found it to be 0.98. Mr. Jones says that this heritability value indicates that 98% of the variance in weight gain among his pigs is determined by genetic differences,…Proteins that are always present in the cell are encoded in genes that are __________ expressed, whereas proteins that are present only in response to a stimulus are encoded by genes that are ______________ expressed. a. timely, extemporaneously b. inducibly, constitutively c. extemporaneously, timely d. constitutively, induciblyThe introduction to this chapter describes the long-term effects of famine on people conceived during the Dutch Hunger Winter. a. What evidence suggests that these are epigenetic effects? b. What additional evidence would help to demonstrate that these changes are due to epigenetic changes?
