If a trait has high heritability: Group of answer choices Hereditary differences account for none of the observed variations in
that characteristic within that population. The environment cannot influence that trait. It is still possible for the environment to influence that trait. The trait is not influenced by heredity.
Heritability refers to the measure of the differences in the gene of a person and how the genes are influenced by the environmental factors and controls the trait.
The heritability is counted between 0 to 1 which is counted on the measure of how the gene is influenced by the environment.
In the given if the heritability is very high that means close to 1 therefore it means the trait is controlled only by the genetics of the person and least influenced by the environmental factors.
Option B, The environment cannot influence that trait.
Explanation:
Heritability is the measure of effectiveness of a gene to explain majority of genetic variations in a given set of population. This can also be measured mathematically in terms of number in a way that if heritability is close to 5 it means that gene is able to explain maximum genetic variations and if the heritability it close to 1 it means that gene is unable to explain the genetic variation and hence the variations are not genetic.
Thus a trait having a high heritability means that it will be inherited and hence will produce genetic variations in offspring. Therefore, the impact of external factors such as environment on genetic variations of offspring will be the least or negligible.
No, it is not alive because water is a non-living thing. Aka it doesn't have cells or organs. The fact that it rolls up on the beach all depends on wind and the gravitational pull of the Earth.
