This process may be more common in bacteria than in eukaryotes, where it occurs through horizontal gene transfer.
This process may be more common in bacteria than in eukaryotes, where it occurs through horizontal gene transfer. One example of this process can be found on Santa Cruz Island among the Medium gound Finch population, whose beaks tend to conform to two different sized ideals, while those with intermediate beaks are selected against. One mechanism proposed to account for this process suggests that, given a particular environment, homozygous individuals may have greater fitness than heterozygous individuals for a certain trait. This model, known as disruptive selection, was first put forward by John Maynard Smith. For 10 points, name this process whereby speciation may occur without the original species leaving its environment, often contrasted to the allopatric variety.
