Which trait, if either, is likely to respond to selection?
Traits that are heritable are more likely to respond to selection, as they can be passed down from one generation to the next. Non-heritable traits are less likely to respond to selection, as they are not influenced by genetic factors.
Heritability refers to the extent to which?
Heritability refers to the extent to which differences in a trait or characteristic within a population can be attributed to genetic differences. It provides an estimate of the proportion of individual differences in a trait that can be explained by genetic factors.
How does natural selection favor an organism's heritable trait?
Natural selection favors a trait by increasing its frequency in a population. Natural selection is differential reproductive success. If one variant of a trait enables an organism to have and raise more offspring successfully than other variants in a particualr environment, then it will become more common in the population.
What is a heritable feature?
Heritability is the proportion of Phenotypic variation in a population that is attributable to genetic variation among individuals. Phenotypic variation among individuals may be due to genetic and/or enviromental factors. Heritability analyses estimate the relative contributions of differences in genetic and non-genetic factors to the total phenotypic variance in a population.
What is a heritable trait becoming common in a population?
If the mutation causes a characteristic that is carried as a dominate trait, then it can spread through a population. Also, if the characteristic that is brought about by the mutation is beneficial, the organism will be better suited to its environment than others. If the organism passes this trait to its offspring, then it is understood that they should survive in a greater ratio than those without the trait and the trait becomes common.
Natural selection can only act upon a certain trait if the trait is?
Heritable, meaning that it can be passed down from one generation to the next through genetic inheritance. Without a genetic basis, natural selection would not be able to change the frequency of that trait in a population over time.
Could the zygote ever obtain a heritable trait that it did not get from it's parents?
Yes, because a trait can be hidden for one generation and return in the next. For example, if a girl had red hair, but neither of her parents had red hair, she could have inherited from her grandparents. Therefore, it can be inherited from someone other than your parents.
What term is used to describe an organism that pass the same trait over many generations?
An organism that passes the same trait over many generations is said to exhibit genetic heritability or have a heritable trait.
What is a permanent heritable change in an allele that produces a different variant of the same trait?
A permanent heritable change in an allele that produces a different variant of the same trait is called a mutation. Mutations can lead to genetic diversity within a population and are the raw material for evolution.
Which trait, if either, is likely to respond to selection?
Traits that are heritable are more likely to respond to selection, as they can be passed down from one generation to the next. Non-heritable traits are less likely to respond to selection, as they are not influenced by genetic factors.

What trait of a wave is described by its wavelenghth?
The wavelength of a wave describes the distance between two successive points of the same phase, such as crest to crest or trough to trough. It is a measure of the spatial extent of a wave pattern.
Is a scar a trait?
A scar is not considered a trait in the biological sense as it is not a heritable characteristic that is passed down from one generation to another. Scars are the result of a wound or injury to the skin that has healed and are typically unique to an individual based on their specific experiences.
What do you call a change of the DNA in an organism that result in a new trait?
A heritable character or genetic character
What is a heritable feature?
Heritability is the proportion of Phenotypic variation in a population that is attributable to genetic variation among individuals. Phenotypic variation among individuals may be due to genetic and/or enviromental factors. Heritability analyses estimate the relative contributions of differences in genetic and non-genetic factors to the total phenotypic variance in a population.
Can cetain behavers be pass down through genes to children?
Certain behavioral traits can. For instance, one can inherit a trait such as risk aversion which may not be expressed in the immediate environment as a behavior, or this trait may be consciously modified into less risky behavior. Still, the trait has been show to be heritable and the evidence supports genetic transmission.
