end, an amino acid is bound. This anticodon binds to the codon region for the amino acid attached to it.
5. A tRNA bearing an amino acid binds to the P-Site (Polypeptide). Another tRNA bearing another amino acid
binds to the A-Site (Amino acyl). The amino acid on the P-Site is bound to the amino acid on the A-Site in an
enzyme called Peptydal Transferace(rRNA).

XXV. Definition of Species, Population, Evolution, and Gene Pool

interbreeding and producing fertile offspring. The species is the fundamental category of taxonomic
classification, ranking below a genus or subgenus.
2. Population - a group of organisms of the same species living in the same place at the same time
3. Evolution - Biological evolution, simply put, is descent with modification. This definitionencompasses small-
scale evolution (changes in gene frequency in a population from one generation to the next) and large-
scale evolution (the descent of different species from a common ancestor over many generations).

classification, ranking below a genus or subgenus.

3. Systematics – study of biodiversity
4. Classification – placing organisms into categories
XXIX. Types of Speciation
Sympatric speciation occurs when populations of a species that share the same habitat become reproductively isolated from
each other. This speciation phenomenon most commonly occurs through polyploidy, in which an offspring or group of
offspring will be produced with twice the normal number of chromosomes. Where a normal individual has two copies of
each chromosome (diploidy), these offspring may have four copies (tetraploidy). A tetraploid individual cannot mate with a
diploid individual, creating reproductive isolation.
Sympatric speciation is rare. It occurs more often among plants than animals, since it is so much easier for plants to self-
fertilize than it is for animals. A tetraploidy plant can fertilize itself and create offspring. For a tetraploidy animal to
reproduce, it must find another animal of the same species but of opposite sex that has also randomly undergone polyploidy.
Allopatric Speciation
Allopatric speciation, the most common form of speciation, occurs when populations of a species become geographically
isolated. When populations become separated, gene flow between them ceases. Over time, the populations may become
genetically different in response to the natural selection imposed by their different environments. If the populations are
relatively small, they may experience a founder effect: the populations may have contained different allelic frequencies
when they were separated. Selection and genetic drift will act differently on these two different genetic backgrounds,
creating genetic differences between the two new species.
Parapatric Speciation
Parapatric speciation is extremely rare. It occurs when populations are separated not by a geographical barrier, such as a
body of water, but by an extreme change in habitat. While populations in these areas may interbreed, they often develop
distinct characteristics and lifestyles. Reproductive isolation in these cases is not geographic but rather temporal or
behavioral. For example, plants that live on boundaries between very distinct climates may flower at different times in
response to their different environments, making them unable to interbreed.
