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.
How is natural environment is changed?
People have changed the natural environment by cutting down trees (deforestation) to make new cities as the population is increasing rapidly and to make paper with them.
How can immigration and emigration alter allele frequencies in a population?
Let us say you have three alleles in a population of beetles. Two colors; brown is recessive to green. Thus you have; GG, which is homozygous dominant and green, you have Gb, which is heterozygous and also green. Then you have bb, which is homozygous recessive. This is your population of beetles. What do you think the allele frequency would be if GG, the homozygous dominant, either immigrated, or emigrated out of or into your population of beetles? Since the frequency of Gb and bb would necessarily go down statistically you would see more green morphologies and a change in genetic allele frequency. Assuming normal conditions.
How have humans changed the natural environment to increase the risk of flooding?
Humans have changed the natural environment to increase the risk of flooding by cutting down trees ( Deforestation ). The trees act as a kind of flood barrier as their roots take in some of the water and the trunk of the tree slows down ground flow. Hope this helps :D
What allele is represented by capital letters?
In a Punnett square, a capital letter denotes the dominant allele and a lowercase letter denotes the recessive allele.
What will happen to frequency of current when voltage is changed using a step up or step down transformer?
Frequency does not change when you use a step-up or step-down transformer. Only current and voltage is changed.

How has jaguars environment changed over the years?
Sadly, yes people ARE cutting down their environment as well as many other animals.

If there is Down syndrome on your husband's side are you likely to have a special needs baby?
You're husband may not necessarily have the down syndrome allele. Also the only way you would have a special needs baby is if you also have the recessive (down syndrome) allele. Here are the chances: If neither of you have the recessive (down syndrome) allele - 0% If one of you have the recessive allele - 0% If you both have the recessive allele - 25% The chances are pretty low but it is not definite that you wont have a special needs baby.
Is Down syndrome found on a dominant allele?
Yes.

What is the frequency spectrum?

How have people been changed by the environment?
people can change the enviroment anywhere, by cutting down trees, littering , killing animals, even being there in the first place
What happens if the frequenCy of wave and its length increase?
That is impossible. Speed of wave c = frequency f times wavelength λ. To have a constant speed, the frequency goes up and the wavelength goes down or the frequency goes down and the wavelength goes up.
