Genetic variation is important because a population has a better chance of surviving and flourishing than a population with limited genetic variation. Genetic diversity also decreases the occurrence of unfavorable inherited traits.
Genetic variation comes from mutations within DNA; the movement of genes from one population to another, or gene flow; and new genetic combinations resulting from sex. When a population contains genetics of individuals who vary significantly, some of the individuals in the group can possess traits that make them resistant to disease or cold, increasing the group's chance for survival when these individuals breed with the others. A small, isolated population's individuals may be forced to breed with close relatives, increasing the occurrence of genetic flaws. When inbreeding occurs, any genetic weaknesses found in the parents can be multiplied in future generations.
Genetic variation also helps organisms survive in different climates and environments. If the environment is unpredictable over time and includes a variety of diseases and predators, some differences among individuals increase the chances of some individuals surviving to reproduce, while others do not. In disease resistance, genetic diversity is important because a disease can decimate a homogeneous population in which all the individuals are equally susceptible to the disease.Learn More
Specialist species are animals that are adapted to a particular thing, such as a specific food or habitat. An example of a specialist species is a tiger salamander, which requires a consistent wetland habitat to breed and eats only insects and worms.Full Answer >
Nucleic acids are biochemical macromolecules that store and transfer genetic information in the cell. They use their stored genetic information to direct the synthesis of new proteins in the cell. New proteins can be synthesized by the ribosomes from the DNA and genes held in the nucleic acids.Full Answer >
The molecular geometry of ClO2 is a bent or V-shape, according to Bristol ChemLabS. ClO2 is the molecular formula for chlorine dioxide. It is a yellowish-green gas that crystallizes to bright orange crystals at -59 degrees Celsius. ClO2 is a potent oxidizing agent used for bleaching and for water treatment.Full Answer >
Protein folding games are entertainment programs designed to encourage players to participate in distributed protein folding experiments. Protein folding models how amino acid chains may function in the body, and simulations give scientists the ability to model new drugs and search for cures much quicker than they could in real-world experiments. By encouraging players worldwide to contribute computing power to the project, these games can speed up research.Full Answer >
