The Effects of Temperature on Crossing Over Frequency

Based on the results obtained in laboratory experiments, the distance from the gene to the centromere depends on temperature and environmental conditions. In Sordaria, changes in recombination frequency were observed under different environmental conditions. Recombination produces a new combination of existing genetic variants, so it may be important in adaptation and evolution (Saleem 2001). Over the years, people have observed how different species adapt to different environmental conditions and new spices have evolved.

The observed recombination frequencies between the two loci are intersection values. It is the crossing frequency between two linked loci (markers) and depends on the mutual distance of the observed loci. For any fixed set of genetic and environmental conditions, the recombination in a particular region of the linked map structure (chromosome) tends to be constant, as is the intersection value for genetic map generation There is. In gene conversion, a part of the genetic material is copied from one chromosome to another chromosome, and the provided chromosome is not changed. During meiosis, gene conversion occurs frequently at the actual site of the recombination event. This is the process by which the DNA sequence is copied from one DNA helix (unchanged) to another DNA helix and its sequence is changed. Genetic transformation is usually studied in fungal crosses, where four individual meiotic products can be conveniently observed.

Exposure to high levels of EMF may result in acute (short-term) effects. The effect that occurs depends on the frequency of radiation. At low frequencies, the effects are in the central nervous system of the body, heating effects occur at high frequencies, body temperature may rise. In fact, these effects are very rare and will not occur in most work situations.

As the temperature rises, global impacts such as severe weather pattern changes, sea level rise, frequency and intensity of extreme weather events will increase. The most vulnerable areas in the world are Earth poles and Africa. These are starting to experience a sharp rise in the average temperature. It is frustrating that people can not stop climate change and can only try to adapt to climate change, not by exacerbating the climate through their own activities. Our own activities have triggered global warming, and we all face the most important environmental problems of climate change. We all recognize climate change, but there is no activity to stop the further increase of atmospheric greenhouse gases still.
