Answer #1

Each of two or more alternative forms of a gene that arise by mutation and are found at the same place on a chromosome.

An allele is an alternative form of a gene (one member of a pair) that is located at a specific position on a specific chromosome. These DNA codings determine distinct traits that can be passed on from parents to offspring throughsexual reproduction. The process by which alleles are transmitted was discovered by Gregor Mendel and formulated in what is known as Mendel's law of segregation.
