To this end, it has been ascertained that carriers for different chromosomal variations occur at different frequencies at different seasons. Such genetic constitutions can be passed on to offsprings. This leads to some offsprings that are better suited to environmental disparities, while others are least suited to prevailing environmental conditions.
In this article, the variations in seasonal adaptability among natural populations of Drosophila pseudoobscura are analyzed. Basically, the article unveils a study targeted towards determination of the impact of the gene combinations on the third chromosome of Drosophila pseudoobscura in their adaptation to varied environmental setup. It aims to show that natural selection plays an integral role in determining the survival of organisms with specific gene combinations. The study was prompted by the observations that seasonal variations occurred within the populations of the organisms. More specifically, it was observed that while certain seasons favored heterozygotes, other seasons were more favorable to homozygotes.
To test the hypothesis to ascertain the heritability of seasonal adaptation, the research uses experimental designs which involved parent-offspring comparisons under artificial environment, in a population cage. Through this comparison, the study was able to show differential death rates with inversion heterozygotes more favored than homozygotes. Further, this study involved use of specifically selected eggs representative of heterozygote or homozygote states exclusively. Such eggs were produced through well-programmed breeding. Despite the conduct of the experiment in artificial setting, the study confidently outlines that the determination of the artificial experiment is an accurate account of the developments in natural habitat.

Theory of Evolution and Evidence for Natural Selection
The author states that natural selection is a key mechanism of evolution, the change in heritable traits of a population over time. It is the differential survival and reproduction of individuals. He thinks that the idea behind natural selection is that certain features provide organisms with advantages that lead to easier survival.
