Galapagos medium finches are found on Santa Cruz and San Cristobal islands which are separated by 100km of ocean. Occasionally individuals from either island fly to the other island to stay. This can alter the allele frequencies of the population through which mechanism?
Galapagos medium finches are found on Santa Cruz and San Cristobal islands which are separated by 100km of ocean. Occasionally individuals from either island fly to the other island to stay. This can alter the allele frequencies of the population through which mechanism?
Allele frequency : It refers to how common an allele is in a population. It is determined by counting how many times the allele appears in the population then dividing by the total number of copies of genes . The gene pool of a population consists of all the copies of all the genes in that population.
Allele frequency can be represented as a decimal, a percentage or a fraction.
In population genetics , allele frequencies show the genetic diversity of a species population or equivalently the richness of it's gene pool.
Allele frequency in a population may change due to gene flow , genetic drift , natural selection and mutation. These are the four causes of evolution. Only mutation cause genetic variation , other three rearrange this variation within and among population.
