∙ 6y agoPhenotypes frequencies in a population vary over time. Phenotypes are determined by genotypes which are determined by combinations of alleles. If a population is in Hardy-Weinberg Equilibrium the allele frequencies will remain constant. Even though the frequency of each allele remains constant, the way that the alleles are paired in individuals will vary, changing the phenotype frequency in each generation.

∙ 7y agoPhenotype (how things look) changes based on the genotypes of the individuals in the population and occurs randomly. The more diverse and larger the population, the more variation is possible from generation to generation. This is the MOST likely reason for changes in phenotypes. Changes in phenotype doesn't necessarily indicate any change in the gene pool.
In population genetics, the term frequency is generally used in conjunction with alleles/genes rather than with phenotype.
The Hardy-Weinburg Principle states that the frequency of an allele in a population will remain the same as long as it is neither selected for or against.
So another reason for changes in phenotype are that certain characteristics are either being selected for or against.

How do parasites serve as a density-dependent limiting factors?
Parasites can limit the growth of a population. They take nourishment from their hosts, often weakening them and causing disease or death. As the population of parasites grow, the population of their hosts tend to decrease.

What is causing the narwhal population to decline?
The main causes for population decline are predation, pollution, maritime transportation, and climate change. The main narwhal predators are hunters, killer whales [Orcinus orca], and polar bears [Ursus maritimus]. The pollution of the air and of the waters is worldwide in its scale and its impact. Maritime transportation contributes to that pollution, and also may affect narwhal migration routes. Climate change affects the life cycle of the narwhal and of narwhal predators and prey. The narwhal population has specific habitat and dietary needs. Any impact on either impacts the narwhal population.

A carcinogen.
Is the heat wave causing your dog to be poorly?
It is possible that the heat wave can be causing a dog to act or feel poorly. Dogs should be kept indoors when the weather becomes too hot and should be given plenty of water to drink.
What phenotype frequency in a population changes after each generation which would most likely be causing this?
Genetic drift, natural selection, and gene flow are factors that can cause changes in phenotype frequency within a population after each generation. These changes occur as a result of random chance events, differential survival and reproduction of individuals, and the introduction of new genetic material from outside sources, respectively.

What phenotype frequency in a population changes after each generation. What would most likely be causing this?
In population genetics the frequency of individual alleles remain constant as long as alleles are neither selected for or against. Phenotypic frequency varies based on the relative frequency of the various dominant and recessive alleles in the population. Further, if selection is taking place phenotype will tend to change in the direction of the allele selected. If the population is small enough there is also the factor of genetic drift, which can change phenotype in one direction within a few generations. Populations are certainly being acted on and alleles selected whether they are obvious phenotypically...if these traits are linked with ones that are visually apparent the change will manifest phenotypically but the change occurs because of linkage to the selected trait as opposed to by selection for the phenotypically obvious one. Some traits give an advantage.

What are the occasional mistakes in copying DNA called and why are they significant for evolutionary change?
Mutations. They, when beneficial, provide variations of organisms genomes for natural selection. Beneficial mutations may confer a slight reproductive advantage to the organism so that genes " promoted " into the next generation change the allele frequency of the population causing evolution.
What 3 types of Selection pressures that affect a population structure?
The 3 types of selection pressure on a population: 1) "Stabilizing selection" = intermediate phenotypes are favored and extremes on both ends are eliminated. 2)"Directional selection" = is a mode of natural selection in which a single phenotype is favored, causing the allele frequency to continuously shift in one direction. 3) "Disruptive selection/ Diversifying selection" = describes changes in population genetics in which extreme values for a trait are favored over intermediate values
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 advantage do microwave have over other cooking appliance?
A by generating very hi frequency material can thermally become hot due to these hi vibration Essentially it cook from inside out as opposed to from the out to the inside of foods. My using microwave radio energy, this frequency causes the fat molecules to vibrate causing the generation of heat, this is why some low fat foods take longer to warm up. When looking at vegetables it's the water molecules that vibrate causing the heat to form.
How did the existence of the baby boomer generation change demand in the US?
The baby boomer generation changed the demand in the US by shear volume. They're the largest population group in the US, and it is moving through our system like a turd thru a bowel. The boomers are a "We want what we want when we want it!" generation, so if they see something they "need" they buy it, causing an increased demand for that product or service.
How does water affect the travel of radio frequency?
Water affects the travel of radio frequency in terms of attenuation. For example, sea water has high attenuation, causing communication hardly possible.
