What causes the change in phenotype frequency in a population after each generation?
Gene mutation causes the phenotype frequency in a population to change after each generation.

What does natural selection cause in a population on a genetic level?
Natural selection causes changes in the frequency of certain genetic traits within a population over time. Traits that confer a survival or reproductive advantage are more likely to be passed on to the next generation, leading to an increase in those beneficial genetic traits in the population.
Evolution is the gradual change in phenotype frequency of a species what process causes evolution?
Evolution is primarily driven by natural selection, which occurs when heritable traits that provide an advantage for survival and reproduction become more common in a population over time. Other processes that can cause evolution include genetic drift, gene flow, and mutations. These processes interact to shape the genetic makeup of a population and lead to changes in phenotype frequency over generations.
What causes an allele frequency to go up in one generation and back down in the next generation?
There are three basic reasons: 1. Natural Selection-- thr environment may have favored the allele in previous generations, but now disfavors it. 2. Genetic Drift-- in every finite population, the frequency of an allele will fluctuate due to chance. For example, the vast majority of sperm fail to fertlize any egg, so allels can be lost this way due to chance. Individuals carrying a copy or copies of an allele may die young due to random accidents, or may never find a mate. These basic chance events cause the frequencies of alleles to fluctuate, and the degree of frequency change depends upon the population size. The greater the population size, the smaller the change in frequency. 3. A combination of both.
Which causes more variation within a population from generation to generation mutation or sexual recombination and Why?
Sexual recombination only takes genes already extant and make new combinations. Mutation presents a brand new variation ( if not neutral or deleterious ) to the eye of natural selection. So, mutation, from generation to generation.
Explain how the founder effect can cause a change in the frequency of alleles in a population?
Genetic variation, variation in alleles of genes, occurs both within and among populations. Genetic variation is important because it provides the "raw material" for natural selection.
What causes a frequency in a population to change after each generation?

A small founding population of a few hundred Europeans in North America had an unusually high frequency of an allele that causes polydactyly . What is an example of?
Genetic Drift
What causes sideband frequency?
If you subtract from the carrier frequency the frequency of the tone that modulates it, then filter out the carrier frequency, then you have a lower sideband frequency. If you add to the carrier frequency, filter out the carrier, then you have an upper sideband frequency.
