.A) To determine if a human trait is heritable, we would best study Group of answer choices. I think it's A. Please explain your answer I'm trying to understand the material a. monozygotic twins that were raised separately, in different environments. b. monozygotic twins that have been raised under similar conditions. c.only distantly related individuals. d. all males or all females. B). To say that a trait exhibits “high heritability” is to say that a. a given set of genes has no influence on a trait. b. there is no difference in genotype between members of the population at the loci in question. c. in a given environment and population, genetic differences have a high degree of influence on the trait compared to environmental influences. d. there is no difference in character between two individuals with the same genotype in question. C). If two populations with identical genetic makeup are raised in different environments, the narrow-sense heritability of a trait of…

Assume that the concordance value for a particular trait is 85% for both monozygotic and dizygotic twins. What can be concluded about this trait? ○ It is caused by environmental factors in dizygotic twins but by genetic factors in monozygotic twins. It is likely caused almost exclusively by genetic factors. It is caused by both genetic factors and environmental factors. It is likely caused almost exclusively by environmental factors. It is caused by genetic factors in dizygotic twins but by environmental factors in monozygotic twins. Incorrect

Heritability of a biological trait is best defined as which of the following? a. The proportion of variation in a trait that is specifically due to genes. b. The proportion of variation in a trait that is due to the environment and genes c. The proportion of variation in a trait that is only due to dominant additive genetic variance. d. The proportion of variation in a trait due to developmental effects.
