- The graphs below show antibiotic production from the same population of bacteria, grown in two different environments-high glucose and low glucose. Number of organisms HIGH GLUCOSE LOW GLUCOSE Amount of antibiotic produced If you calculate the heritability of antibiotic production for this population of bacteria when grown in low glucose compared to when it is grown in high glucose, the estimated heritability value Incorrect will be smaller in the low glucose than in the high glucose. will not be possible to estimate because you don't know the genotypic variation. will be larger in the low glucose than in the high glucose. will be the same in both environments. X XIn a study conducted on human height, heritability estimates that were initially done on children with an average age of 5 years old was 74%. Heritability estimates were again performed on the same individuals when they reached adulthood with an average of 40 years old. The result was 30%. Explain the results.A danger in computing heritability values from studiesinvolving genetically related individuals is the possibility that theseindividuals share more similar environments than do unrelatedindividuals. In the experiment shown in Figure 24.8, which dataare the most compelling evidence that ridge count is not causedby genetically related individuals sharing common environments?Explain
- In the following table, average differences of height, weight,and fingerprint ridge count between monozygotic twins (rearedtogether and apart), dizygotic twins, and nontwin siblings arecompared: Based on the data in this table, which of these quantitative traitshas the highest heritability values?What is the importance of the comparison of traits between adopted and natural children in determining heritability? What assumption about the environment is made in this case?Flower color in the varieties of pea plants studied by Mendel is controlled by alleles at a single locus. A group of peas homozygous for purple flowers is grown. Careful study of the plants reveals that all their flowers are purple, but there is some variation in the intensity of the purple color. What would the estimated heritability be for this variation in flower color? Explain your answer.
- If all the genetic variance in a character is additive, what is the value of narrow sense heritability? Group of answer choices 1 0.5 0Which of the following statements about complex traits is/are TRUE? Twin studies help to tease apart the contribution of genetic and environmental factors to phenotypic variations. When describing quantitative traits, a high variance indicates that most individual values are not very close to the mean. Genetic factors determine Mendelian traits, while environmental factors determine complex traits. Both additive and dominant effect falls in the category of narrow sense heritability and can be directly passed on from parents to offspring.What does a heritability score tell us about HOW genes and environment interact in an individual to produce a trait?
