Genetic polymorphism occurs as a result of natural selection. It represents an equilibrium between members of the same species, and makes use of balancing selection for conservation.
Biologists might use a combination of morphological characteristics, genetic analysis, behavior observations, and reproductive compatibility to determine if two organisms are of the same species. These methods help provide a comprehensive understanding of the relationship between different organisms and the boundaries of a species.
Organisms in the same family
This is a population. More formally, a population is a group of organisms of the same species living in the same area at the same time eg the dandelions in a field make up the population of dandelions; the daisies in the same field make up a separate population, the daisy population. Species are different kinds of organisms which can breed with each other but not with other species eg humans are one species, chimpanzees are another and they cannot interbreed.
If two organisms are able to mate and produce fertile offspring, then they are of the same species.Horses and donkeys are two different species because if they mate, they produce a mule which is sterile (not fertile). This shows horses and donkeys are of different species.
One untrue statement about DNA is that it is the only genetic material in living organisms. Another untrue statement is that all DNA is organized in the same way in all organisms. Additionally, it is false to say that DNA is a protein.
The knowledge of DNA makes for more accurate classification of organisms because the scientists can examine certain species of organisms and see if there are related or closely related to determine weather or not they can be classified in the same group or not.
Although DNA is composed of the same four nucleotides in all organisms, the sequence of nucleotides is different for each species

Polymorphic DNA is a stretch or multiple stretches of DNA that have high variability among individuals. Since the chance of DNA being different among these stretches in two different people, these pieces of DNA are commonly used for identification purposes.
Yes, all living organisms share the same four nucleotides that make up DNA: adenine, thymine, cytosine, and guanine. The unique arrangement and quantity of these nucleotides in an organism's DNA are what determine its genetic characteristics and differences from other organisms. These variations in DNA sequence and content contribute to the diversity seen among different species.
Scientists use genetic markers such as microsatellites or single nucleotide polymorphisms (SNPs) in DNA to determine individual identities of organisms within the same species. These markers show variations in DNA sequences that can be used to distinguish one individual from another.
Their DNA has the same nucleotide bases, but in different patterns. DNA forms the building blocks of all living things, regardless of species.

Yes, DNA testing methods can vary between species due to differences in genome size, structure, and genetic markers. While the basic principles of DNA testing are similar across organisms, specific techniques and protocols may need to be tailored to the species being studied.

The universal structure of DNA ensures genetic information can be passed on accurately during cell division and reproduction. This consistency facilitates the sharing of genes between different organisms and allows for the development of genetic engineering and biotechnology that can be applied across species. Understanding this common structure also helps in studying evolutionary relationships between different organisms.
