Which of the following statements would be true of ahuman trait that has high heritability in a populationof one country?a. The phenotypic difference within monozygotic twinpairs would be about the same as the phenotypic differences among members of dizygotic twin pairs.b. Very little phenotypic variation exists betweenmonozygotic twins but high variability exists between dizygotic twins.c. The trait would have the same heritability in a population of another country
Genetic Variation
Genetic variation refers to the variation in the genome sequences between individual organisms of a species. Individual differences or population differences can both be referred to as genetic variations. It is primarily caused by mutation, but other factors such as genetic drift and sexual reproduction also play a major role.
Quantitative Genetics
Quantitative genetics is the part of genetics that deals with the continuous trait, where the expression of various genes influences the phenotypes. Thus genes are expressed together to produce a trait with continuous variability. This is unlike the classical traits or qualitative traits, where each trait is controlled by the expression of a single or very few genes to produce a discontinuous variation.
Which of the following statements would be true of a
human trait that has high heritability in a population
of one country?
a. The
pairs would be about the same as the phenotypic differences among members of dizygotic twin pairs.
b. Very little phenotypic variation exists between
monozygotic twins but high variability exists between dizygotic twins.
c. The trait would have the same heritability in a population of another country
