<span>Alleles are each of two or more alternative forms of a gene that are found at the same position in a chromosome. Traits on the other hand, are the characteristics that are defined by genes. So the combination of alleles for a gene is what manifests itself into a trait.</span>
<h2>Answer and Explanation </h2>
The genetic recombination is a biological process in which the recombination of homologous DNA strand occurs. There are three types of genetic recombination in human being that is :
Human Reproducation that is by introducing new gene combination to the population.
By cell Mutation is it that is changes in the DNA.
By Gene flow it is that is by movement of a gene from one population to another population.
Cell maintain homeostasis through diffusion in isotonic solution. Isotonic means that the concentrations are the same on either side of the membrane, maintaining homeostasis.
Genetic engineering is the direct manipulation of a specific gene. I would use it in this scenario
