Genetic variation means that biological systems – individuals and populations –
are different over space. Each gene pool includes various alleles of genes. The
variation occurs both with...
Mutations and gene duplications are the only sources of completely new alleles
in a population. Transcription errors at the gene level and the chromosome level
For a given population, there are three sources of variation: mutation, ... It is
obvious that the rate of increase of the new allele is extremely slow and that it
gets .... Inbreeding takes the genetic variation present within the original
population and ...
What is Harmful or helpful and is considered to be the source for new alleles and
a main contributor to .... Which are sources of new alleles within a population?
In this way, new DNA variants are passed on to the next generation. If the
mutation affects a gene, it will result in a new version of that gene – a new allele.
