The study explains how bright colors developed and changed in male guppies

Exceptional characteristics observed only in some types of men – such as colored feathers of feathers or butterflies – are partly explained by the behavior of genes, according to research.

The findings help to understand this phenomenon, which can help the animals attract partners, while making them more vulnerable to predators.

The researchers studied the genetics of guppy fish whose men are bright in color compared to dark brown females.

Researchers at universities in Edinburgh and Exeter used fish populations that were bred in the laboratory to conduct detailed studies on the transmission of genes during reproduction.

Scientists have compared genetic maps of several generations, along with whole genetic codes, to understand how genes inherited over time.

In typical sexual reproduction, a plurality of genes from each parent would randomly merged to create offspring with a mixture of the properties of both.

In males of males, however, it was found that gene packets in cells – known as chromosomes – exchange genes from peaks.

Many genes, including those that cause light colors, are transmitted from one male generation to the next, almost undisturbed, and are rarely mixed with the genes inherited by fehttps: //www.ed.ac.uk/biology/news -events / news- 2019 / color-male-fish-have-gene-for-thank-your-men.

Researchers also found that this low level of genetic mixing between the sexes allowed the evolution of the male's light-colored appearance, as it retained the characteristic of several generations.

Their study, supported by the European Research Council, was published in 2006. T Proceedings of the National Academy of Sciences.

Roberta Bergero of the University of Edinburgh School of Biological Sciences, who led the study, said: "An insight into exchanges between men and women's genes helped explain how these bright colors developed and expanded in male guppies."
