The frequency of the allele represents the percentage of that allele in the gene pool
They're not.
Genes are the medium by which inherited traits are passed on to offspring. It is inherited traits, and thus genes, that receive positive or negative selection.
The entire collection of genes among a population is called the "gene pool".
alternative forms of a gene are called as alleles..
If you have 2 dominant alleles, the gene will be dominant, if you have 2 recessive alleles, the gene will be recessive. But if you have 1 recessive and 1 dominant, the Dominant allele will mask the recessive one.
Genes and alleles are related because alleles are inside a gene. Genes are made up by alleles. A gene is DNA. The allele is like piece of DNA inside a gene.
Gene or allele frequency
The relationship between the frequencies of three alleles of a gene in a population is that they must add up to 1 (100). This is known as the Hardy-Weinberg equilibrium. The frequencies of the three alleles can be represented as p, q, and r, and the equation p q r 1 must hold true in a population for genetic equilibrium to be maintained.
It's the other way around: natural selection is the natural process that causes the frequencies of occurence of alleles in the population gene pool to shift.
They're not.
DNA is composed of long strings of nucleic acid sequences, but not all of them code for proteins. The ones that do are called genes. Alleles are different versions of a certain gene. For example, the gene that codes for blood type has 3 different alleles, A, B, and O. The genes that code for hair and eye color also have many different alleles.
It's the other way around: natural selection is the natural process that causes the frequencies of occurence of alleles in the population gene pool to shift.
Mutation can create new alleles, therfore can change allele frequencies in a population.
Different versions of the same gene are called
Alleles are different forms of a gene that can determine specific traits in an organism. Traits are characteristics or features that are influenced by the alleles present in an individual's genetic makeup. In other words, alleles and traits are related because alleles determine the traits that an organism will exhibit.
In the strict sense, no. Mutations happen to individuals and are only heritable in the germ line. Populations have allele frequencies in their gene pools. So, the mutation must be beneficial, lucky enough that it original carrier passes it on intact and that it is driven into the populations gene pool in sufficient number, by having reproductive success, to change allele frequencies.
Alleles are alternate forms of the same gene. A gene is the basic physical unit of heredity that is passed on from a parent to their children.
