It is interesting that because all life on this planet uses information in the form of either DNA, RNA or both, and that the same bases can be used, and that the genetic code is almost always the same using three of those bases to code for one of twenty amino acid. Because now genes can be cloned and moved from one organism into another and the foreign gene will make the same protein! So, a gene from a bacteria can be expressed in a plant to make the same protein that was made in the bacteria. The process of taking a gene from one species and expressing it in the genome of another species is called

What are the types of genetic recombination

To answer this question, researchers studied populations of the dusky salamander (desmognathus ochrophaeus) living on different mountain ranges in the southern appalachian mountains. the researchers tested the reproductive isolation of pairs of salamander populations by leaving one male and one female together and later checking the females for the presence of sperm. four mating combinations were tested for each pair of populations (a and b)—two within the same population (female a with male a and female b with male b) and two between populations (female a with male b and female b with male a). the proportion of successful matings for each mating combination was measured. for example, when all the matings of a particular combination were successful, the researchers gave it a value of 1; when none of the matings were successful, they gave it a value of 0. then the researchers calculated an index of reproductive isolation that ranged from 0 (no isolation) to 2 (full isolation). the reproductive isolation value for two populations is the sum of the proportion of successful matings of each type within populations (aa + bb) minus the sum of the proportion of successful matings of each type between populations (ab + ba). the table provides data for the geographic distances and reproductive isolation values for 27 pairs of dusky salamander populations.
