Assume you have a population of people of various genetically influenced heights; they all varied in height potential. They all were raised in an environment that was deprived of basic nutrients and all were somewhat stunted in growth. A person that would have been tall in a normal environment passes on those genes for tallness in his deprived -of -nutrients environment, so his sons/daughters, if properly feed, would grow tall. So you see, natural selection must work on the genetic/individual variation and not variations that are not inherited.

∙ 11y agoHow would it be inherited? Acclimatization, to the environment, such as having an increased hematocrit at higher elevations, could occur but it is not heritable and it is not considered naturally selected.

∙ 12y agoNo. Some traits are present, but natural selection is blind to them. Traits such as men's nipples, but traits that are not there can not be acted upon as natural selection is the " blind watcher maker " and can not see the future need but must tinker with what is available now.

∙ 12y agoNo. No variation in organisms against the immediate environment and there would be nothing to select for as all would have the same average survivability and reproductive success.

∙ 13y agono, primitive natural selection only affects genetic traits that are passed from parent to offspring.

Natural selection can only act upon a certain trait if the trait is?
heritable
What is disputive selection?
When natural selection favors extreme variations of a trait (ex. Biggest & Smallest)
What is Stabilizing Selection and Distruptive selection?
A type of natural selection in which genetic diversity decreases as the population stabilizes on a particular trait value.
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 natural selection that acts against one type of extreme form of a polyygenic trait to reduce genetic variation and change the average value of a trait within a population called?
directional selection
Natural selection can only act upon a certain trait if the trait is?
heritable
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.
How could this be an advantage to the insects how could this trait have evolved through natural selection?
Well this could be an advantage to the insects because the insects can conceal with the color of the sticks. This trait could have evolved the through natural selection because its a chance of staying alive.
Does natural selection on single-gene trait cannot lead to changes in allele frequencies?
Natural selection on a single-gene trait can lead to changes in allele frequencies for the alleles of that gene.
What is disputive selection?
When natural selection favors extreme variations of a trait (ex. Biggest & Smallest)
Through natural selection a trait that is favorable will become an alternate trait that is less favorable?
more frequent than
What is Stabilizing Selection and Distruptive selection?
A type of natural selection in which genetic diversity decreases as the population stabilizes on a particular trait value.
What characteristic witin populations causes natural selection to occur?
The characteristic within the population that causes natural selection to occur is that individuals within a given population are not all identical because they vary. The other characteristic that causes natural selection to occur is that some variants are better than the others.
What two factors are required for a character or trait to change over time in population which is adapting through natural selection?
The two factors required for a character of trait to change over time through natural selection are heritability of the trait and a differentiation of fitness between traits.
What determines which trait will be passed on to the next generation in the greatest frequency?
natural selection
How can organisms be produced with desired trait?
Through selective breeding or by natural selection.
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.
