A team of researchers from Linköping University suggested that the brains of male and female fruit flies become asexual as they age. Age-related changes occur in both sexes, however, the male brain tends to be more feminine than the female brain.
The study findings were published in the journal – Proceedings of the
Royal Society of London.
Vulnerable individuals cannot afford to “invest” in sexual behavior
degree as their healthy conspiracy, which is a well known fact. it is unclear,
However, does old age, which weakens people, also cause deficiency
interest in sexual activity.
Going “all in” on breeding may be the best option for people who are nearing the end of their lives in order to pass on their genes before it is too late. The brain controls sexual behavior, so the researchers looked at how the expression of specific genes changed with age in young males and females to learn what happens to sex differences in this tissue in fruit flies.
According to one of the primary authors of the study, Dr. Antonio Malacrin, who is
Currently working at the University of Reggio Calabria in Italy, “Our Results”
Demonstrates that gene expression is upregulated in male and female brains
is similar with age, and that both sexes contribute to this pattern.”
Study shows reduced gene expression in older women
and increased in older men if gene expression is higher in the brain
Younger females than younger males, and vice versa for genes with higher
Expression in young men.
According to Antonino Malacrin, “The results also demonstrate that
The changes are more pronounced in men than in women.”
Since there is probably a weak correlation between investment in sexual
Symptoms and reproductive success in women, women have a higher age than men
slowly than in men.
A female fruit fly only needs to choose how much energy she has available to breed, while a male fruit fly must guide other males to quickly find females and mate them through a challenging dance performance. Must agree.
Age implies that fewer resources are available to both sexes to invest in reproduction and other activities, but males face greater costs of increased investment due to male-to-male competition.
Senior Associate Professor in the Department of Physics, Chemistry, and
biology (IFM) at Linköping University and principal investigator of the study,
Urban Friborg, claims that if you continue to expend the same amount of energy
If you breed when you were younger, you will have nothing left
to live
Studies on other animals, including humans, that have focused mainly on age-
Related changes in gene expression of a sex have produced results that indicate
in the same direction. This suggests that many other animals may experience
Similar results to fruit flies.
Even though the two populations of fruit flies studied are different
In terms of the genes involved, Urban Friborg notes that
The general results are the same in both.
The study’s findings are similar to those the team previously discovered
investigation. Males and females in that study fly with higher and lower genetics
Quality was compared for gender differences in gene expression.
Earlier studies showed that decreased genetic quality resulted in more similar gene expression in male and female flies, in much the same way that gender differences decrease with age.
Once again, males changed their gene expression more than females.
Study doesn’t reveal what molecular signal linked to aging
Responsible for the diminishing gender gap in the brain.
If the signaling molecule is shared by other species, further research on this topic may prove useful.
