Genetic variation is the total amount of genetic diversity present within a species or population. The amount of genetic variation in a population will depend on a variety of factors, including the size of the population, the type of reproduction, and environmental influences.

The primary way to increase genetic variation in a population is through mutation. Mutations are random changes in the genetic code that can lead to new traits or characteristics. Mutations can be caused by environmental factors, such as exposure to radiation or chemicals, or they can occur spontaneously. Mutations can be beneficial, neutral, or detrimental to the organism, but they do lead to increased genetic variation.

Another way to increase genetic variation in a population is through migration. When individuals from different populations mate, they bring with them different alleles from their home population, increasing the genetic diversity of the new population. This is especially important for populations that are geographically isolated, such as island populations.

Another factor that can increase genetic variation is sexual selection. This is the process by which individuals select mates based on certain desired traits. This can lead to an increase in the number of different alleles in the population, as individuals with certain traits will be more likely to reproduce.

Finally, gene flow is a process that can increase genetic variation in a population. Gene flow is when individuals from one population move to another population and mate with individuals in the new population. This can bring in alleles from the original population, increasing the genetic diversity of the new population.

Overall, while mutation, migration, sexual selection, and gene flow are all important factors in increasing genetic variation in a population, it is important to note that genetic variation can also be decreased by inbreeding and genetic drift. Inbreeding is when individuals mate with close relatives, reducing the number of alleles in the population and leading to decreased genetic variation. Genetic drift is when random fluctuations in allele frequencies occur due to a small population size, leading to decreased genetic variation. Therefore, it is important to consider all of these factors when trying to increase genetic variation in a population.

Can one explain how Genetic Programming is a branch of Genetic Algorithms?

The term genetic algorithm can refer to the specific algorithm developed by John Holland in the 1970s, but is often used as a cover term for many different algorithms that all use an evolutionary process of repeatedly selecting a proportion of the best members of a population of solutions according to some specified criterion and using them to produce a new population of solutions with some chance of mutation and/or recombination. After repeating this procedure many times, the quality of solutions in the population tends to increase as judged by the selection criterion.Evolutionary programming is what this technique is called when the evolving solutions can be interpreted as computer programs or functions, and this has consequences for the kinds of mutation and recombination operators can be used to modify solutions in the population.


Genetic differences between populations tend to be reduced by?

Gene flow tends to reduce diffences between populations.


Why is genetic diversity in a gene pool crucial to that populations survival?

Too much inbreeding will reinforce bad traits and lead to deformities. Any species has flaws. Mixing the gene pool tends to cancel out the bad.


Explain how you can determine the type of correlation for a set of data pairs by examining the data in a table without drawing a scatter plot?

"If y tends to increase as x increases, then the data have a positive correlation. If y tends to decrease as x increases, then the data have a negative correlation. If the points show no correlation, then the data have approximately no correlation."

How does diploidy help to preserve genetic variation?

It allows recessive alleles that may not be favored in the current environment to be preserved in the gene pool by propagation in heterozygotes.Natural selection tends to decrease genetic variation. Recessive alleles are shielded from natural selection in heterozygotes.

If natural selection tends to reduce variation then how is variation preserved within the population?

Natural selection doesn't reduce variation. Variation is regulated by the rate of mutation.Natural selection reduces the chance of bad variation from being passed on and increases the chances for good variation to be passed on.
