Speciation is the attainment of reproductive isolation.
The common and similar bone structure in many diverse species of vertebrate limbs is an example of morphological divergence or homologous structures . Conjugation is the transfer of genetic information from one bacterium to another via a specialized plasmid called the F factor. A severe reduction in population size brought about by intense selective pressure or natural disaster is called a Bottleneck . A mutation is a heritable change in the DNA sequence of a gene. Assume that a population is in genetic equilibrium for the two alleles of a gene, X and x, and this population gives rise to a subsequent generation of 100 individuals.
