Sex Guarantees Disease-Free Life In Offspring
The more we have sex, the more we avoid bad genetic mutations leading to less chances of developing diseases in offspring over time, finds an interesting study.
Researchers from the University of Montreal and the Sainte-Justine University Hospital Research Centre in Canada have revealed how humanity’s predispositions to disease gradually decrease the more we mix our genetic material together through sexual reproduction.
“This discovery gives us a better understanding of how we, as humans, become more or less at risk of developing or contracting diseases,” said study leader Philip Awadalla from the University of Montreal.
“It also tells scientists more precisely where to look in the human genome to find disease-enabling mutations which should speed up the discovery and identification of mutations associated with specific diseases,” he added.
More specifically, the team discovered that the segments of the human genome that do not recombine carry a significantly greater proportion of the more disease-enabling genetic mutations.
Until chromosome recombination eventually occurs, these segments accumulate more and more bad mutations.
In other words, as far as susceptibility to disease is concerned, our genetic material actually worsens before it gets better.
“Thankfully, disease-enabling mutations are eventually shuffled off our genetic code through sexual reproduction. But since these mutations rest on less dynamic segments of our genome, the process can potentially take many hundreds of generations,” Awadalla explained.
This discovery was made possible by the availability in recent years of repositories of biological samples and genetic data from different populations around the globe.
Awadalla and his team studied the sequenced genomes of hundreds of individuals from Canada’s CARTaGENE genetic data repository and the multinational 1,000 Genomes Project.
They found that the proportion of mutations associated with disease was significantly higher in low-recombining segments known as “coldspots” relative to highly-recombining regions.
The bad mutations in these “coldspots” were generally more damaging than the mutations in the highly recombining segments.
“Researchers and health authorities will be able to apply this new information to develop more effective treatments and prevention programmes,” Awadalla added.

Please do not give this message to the northern and eastern parts of zambia. We do not want an increase in offspring that follow their parents in terms of being illiterate and voting on the basis of flimsy promises. Zambia at the most needs to promote increase in child birth to those families that are educated and able to ensure their kids willbe the same. Vote UPND

@Jane Mulenga AKA New educated Zambia, you are being worthless: In which election, kanshi? Is voting still going on? Awe% kuleni bane. You are becoming the most boring blogger here. One knows what you are about to say even before you say it!!
Shameful!!

New Educated fimo fimo and Judge Joe Bidden are HH’s paid toilet cleaners hoping to be made Cabinet Ministers if he ever becomes President. They are confused with effects of smoking cow dung.

@New Educated Zambia a.k.a Jane Mulenga, what satisfaction do you get out of your solicitation for vitriol and insults from other bloggers on these sites towards you? An EJACULATION through your a$$hole every time you vomit garbage?
You are such a low-life wannabe agitator f00l—enough already!!!

iwe educated ponyo ponyo do debate like a mature man. if wht you say is wht u vall maturity then ninshi ulibolo sana. so let me tell you now. any time whn you want to put something on this fora first think of icilibolo chakwa wiso nomukongo wakwa no. wemwana wansanya.
