Frequency of recombinations

Frequency of recombinations in chromosomal genes

**Recombination frequency** in a chromosomal gene is the number of mobile elements that are located between neighboring genes and lead to their recombination. Transposable elements are DNA fragments that can move throughout the genome and change its structure. Thanks to them, genetic information quickly accumulates and is transmitted from generation to generation.

The frequency of recombination can vary depending on various factors, such as population size, number of genes, genome type, level of mutagenicity, etc. In populations with many genotypes and variants of gene distribution, the frequency of recombination will be higher than in populations with limited genome variants.

However, not all mobile elements influence the recombination frequency equally. Some transposable elements may engage in rapid gene exchange, resulting in their genes being mixed and passed on over generations. Others can reduce or even eliminate recombination activity, which significantly slows down the process of gene exchange.

For example, transposable elements can be used to study the relationship between genes in a genome. If genetic factors interact at the location of the transposable element, then during gene exchange a displacement of these factors can occur, and then the presence of a connection between them can be traced. Frequency analysis of transposable elements can also provide information about the consequences of point mutations,
