Can the trait of rate of development be acted upon by natural selection?

Any morphological and behavioral trait that is in hard inheritance, genetic inheritance. Remember, all organisms are variants and these traits vary from organism to organism and so natural selection selects the best adapted trait among the population of organisms against the immediate environment. The trait that confers better survivability and reproductive success, So, evolution, the change in allele frequency over time in a population of organisms, occurs.
Only natural selection confers adaptive change leading to speciation. Epigenetic changes are not adaptive changers.

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 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 will never favor those members of a population that have an extreme variation of a trait?
False my friend
Natural selection can only act upon a certain trait if the trait is?
heritable
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)
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.
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 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.
When organisms with certain desirable trait are mated?
Natural selection is when organisms with a desirable trait mate and produce babies with that trait. The process of elimination will eventually diminish any that do not have that trait/
Can natural selection act on a population with no variation traits?
The trait is the same for all organisms.
What terms describes natural selection that acts against intermediate forms of a polygenic trait to increase genetic variation while not changing the average value of a trait within?
Disruptive selection
