Does natural selection on single-gene trait cannot lead to changes in allele frequencies?
Natural selection acting on a single-gene trait can lead to changes in allele frequencies within a population. If individuals with a certain allele have a selective advantage, they are more likely to survive and reproduce, leading to an increase in the frequency of that allele in the population over time. This process is known as directional selection.
How does nonrandom mating affect evolution?
Non-random mating is otherwise known as sexual selection. Some see this as distinct from natural selection, but I think that sexual selection is merely a form of, or perhaps more a complication of natural selection. Selection, natural or sexual, is the effect that "guides" evolution, that allows evolution to produce populations suited to their environment.
How does natural selection impact the evolution of individual organisms within a population, and does it ultimately lead to changes in the entire population over time?
Natural selection is a process where organisms with advantageous traits are more likely to survive and reproduce, passing on those traits to their offspring. This leads to changes in individual organisms within a population over time. If these advantageous traits continue to provide a survival advantage, they can become more common in the population, ultimately leading to changes in the entire population.
What is part of micro evolution?
Microevolution is the small-scale changes in allele frequencies within a population over generations. It can include mutations, gene flow, genetic drift, and natural selection acting on specific traits within a population. These changes can lead to adaptations and variations in a population over time.
Minor changes can occur over a few generations the changes produced variations in population this relates to what?
This phenomenon relates to the process of evolution by natural selection, where favorable variations that help individuals survive and reproduce become more common in a population over generations. These minor changes accumulate and can lead to significant adaptations in a population over time.
What will natural selection eventually lead to in a population?
Changes in morphology and behaviour.Speciation.Extinction.

What tends to result in a population whose individuals have extreme traits?
Natural selection can lead to extreme traits in a population if those traits provide a significant advantage in survival or reproduction. Genetic drift can also lead to extreme traits if there are random fluctuations in the frequency of alleles in a population. Additionally, sexual selection can drive the evolution of extreme traits if individuals with those traits are preferred as mates.
Does sexual selection lead to violence?
Sexual selection, which is the process by which certain traits are favored for reproduction, can indeed lead to violence in some species. In some cases, competition over mates can result in aggressive behaviors such as fighting or intimidation. However, it is important to note that not all forms of sexual selection result in violence, and many species have alternative strategies for mate selection that do not involve aggression.

What is the result of artificial selection?
Artificial selection results in the intentional breeding of plants or animals for specific desired traits. Over time, this can lead to changes in the genetic makeup of a population, resulting in organisms with traits that are favored by humans.

Changes in groups of organisms over time produce variations in a population. This relates to .?
both Macroevolution and Microevolution Good luck with Novanet. God help you.
How does sexual reproduction lead to natural selection?
Because sexual reproduction produces new and unique combinations of maternal and paternal alleles in each offspring. That leads to a great diversity of individuals in the population. Natural selection can then act on the population to give some individuals greater fitness than others, leading to changes in the population over time. -love to help CR
How does sexual selection differ from natural selection in shaping the evolution of species?
Sexual selection and natural selection are both mechanisms that drive evolution, but they differ in their focus. Natural selection acts on traits that increase an organism's chances of survival and reproduction in its environment, while sexual selection specifically targets traits that enhance an individual's ability to attract mates and reproduce. This can lead to the evolution of characteristics that may not necessarily improve survival, but increase reproductive success.
