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

∙ 11y agoPhenotype is determined by what genes you carry. There are many variations on a gene called alleles. Depending on what alleles you inherit from your parents (use a Punnet Square for that) you get a different phenotype. In a population, mating patterns can also be a big thing. Often times, animals will refuse to mate with creatures that have different appearances or phenotypes than them. Because of this, that particular phenotype is rarely seen.

∙ 13y agoAn organism's phenotype, the physical characteristics it possesses, is determined by it's genotype, the genes it has for a particular trait. Let's say, for example, a rose can be 2 colors, red or white, and red is dominant. If the rose has an Rr or RR genotype, it will be red, whereas it can only be white if it has both recessive alleles, or rr.

Evolution is the gradual change in phenotype frequency of a species what process causes evolution?
Mutation, genetic drift, gene flow and the driver of adaptive change, natural selection.
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?
Gene mutation causes the phenotype frequency in a population to change after each generation.
what causes the Phenotype frequency in a population to change after each generation. Which would most likely be causing this?
competition between organisms

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

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.
What is an organisms way to express its genotype?
No, the genotype is the genetic composition of the organism. On the other hand, the phenotype is the physical composition of the organism. For example, a gene that causes a bird's feathers to be black in color is the genotype and the phenotype is the actual observable of the black feathers.
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.
What causes Parametric Excitation in Frequency Resonators?

What are the causes of optimum population?
Optimum population refers to a balance between available resources and the number of people in a given area. Causes of achieving optimum population include effective family planning programs, access to education and healthcare, economic opportunities, and social welfare systems that support a sustainable population size. Maintaining a balance between population and available resources helps ensure a higher quality of life for everyone in the community.
