Anaphase I of meiosis
Different versions of the same gene are called
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.
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.
the alternative form of a gene is called an "allele."
Alleles
Gene flow
The two different molecular forms of a gene are called alleles.
The alleles are the different forms of the gene. This is simplified, but an example might be, if the gene is "eye color," the alleles would be "green, blue, brown, etc." The variations in the gene are the alleles.
That depends on the gene: some genes have only a few alleles, some genes have hundreds or even thousands of alleles.
Alleles
Evolution changes the relative frequency of alleles in a gene pool through mechanisms such as natural selection, genetic drift, gene flow, and mutation. These processes can cause certain alleles to become more or less common in the population over time, leading to changes in the genetic makeup of the population. This happens because individuals with beneficial alleles that help them survive and reproduce are more likely to pass those alleles on to the next generation, increasing their frequency in the gene pool.
A different version of the same gene is called an allele. Alleles are variations in the DNA sequence of a gene that can result in different traits or characteristics. Individuals inherit two alleles for each gene, one from each parent.
