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.
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.
Heritability refers to the extent to which?
trait differences among individuals are attributable to genetic variations.
What do the terms dominant and recessive mean?
ACCORDING TO GREGOR MENDEL'S LAW OF DOMINANCE:- Dominant Allele refers to the expressed trait in a pair of genes,while the dormant,suppressed trait is the recessive allele.
How does evolution affect us?
Very slowly. Each generation has some differences from the preceding generations. The survivors from one generation pass their genes on to subsequent ones. A trait that increases survival rate is passed on more frequently than a trait which is detrimental to procreation.
Natural selection can only act upon a certain trait if the trait is?
heritable
What the importance of family trait?
family trait will help you to know about what is the health status of family.it helps you to know about the heritable trait in the family.
What is a permanent heritable change in an allele that produces a different variant of the same trait?
heritable change occurs in a line of descent
What is a heritable trait becoming common in 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.
What do you call a change of the DNA in an organism that result in a new trait?
A heritable character or genetic character

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.
How do genes cause differences in a particular trait?
genes are blueprints to specific traits
What is continuously varying trait?
A discontinuous trait is the opposite of a continuous trait. They are "either/or" traits that do not have any range. An example would be the sex of an offspring, whereas an example of a continuous trait would be haircolor, where many options are available.
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 is a statistical estimate of the proportion of the total variance in some trait that is attributable to genetic differences among individuals within a group?
Heritability is the statistical estimate of the proportion of the total variance in a trait that is attributed to genetic differences among individuals within a group. It provides a way to quantify the extent to which genetic factors contribute to individual differences in a specific trait within a population.
Heritability refers to the extent to which?
trait differences among individuals are attributable to genetic variations.
