COVID-19 IN NIGERIA: WE SAY NO TO CHINA INTERVENTION

Can the world ever trust China again? Would Nigeria romance with the prime suspect of the current global crisis (COVID-19)? How can we? In 2012 China handed over a fully funded and built headquarters building in Addis Ababa, Ethiopia to the African Union (AU). A great gesture of friendship and solidarity, perhaps. But not long after, it was alleged to have been bugged, leaking vital, confidential information of the Union to China in faraway Shanghai! True or false, the Union had to change its computer servers to check the alleged mischief. But issues of health are different. Misfiring means losing a life, or even lives. On a national scale, that can amount to thousands. Painful loss. Avoidable loss. The authorities must tread with caution here. Face masks, test kits, ventilators, vaccine and doctors - all from or of China. Hmmmm, caution we must exercise. Until now we have been using our indigenous doctors, and they have been doing well. WHY CHANGE THE WINNING TEAM? Please let us DISCARD this idea of Chinese intervention. WE DON'T NEED IT. Let us stay safe Stay indigenous. Stay Nigerian We shall overcome

Could Two People Who Aren’t Twins Have The Same DNA?



 BOYS TWINS 
Your DNA is arranged into chromosomes, which are grouped into 23 pairs. When a sperm cell is manufactured, the father’s genome is split in two, so that each sperm receives one chromosome from each of the 23 pairs, and the same thing happens with the egg cells in the mother.

When the egg and the sperm combine to form an embryo, the resulting genome contains half the mother’s chromosomes and half the father’s, chosen essentially at random. Theoretically, same-sex siblings could be created with the same selection of chromosomes, but the odds of this happening would be one in 246 or about 70 trillion.

In  fact, it’s even less likely than that. Before the chromosomes pairs fully separate, they often swap individual genes from one chromosomes to another in the pair. This means that even if successive sperm were manufactured with exactly the same chromosome selection, they wouldn’t contain the same genes. Of course, a lot of the gene pairs in your genome are actually’ the same, so it wouldn’t matter which copy you used, but the odds of constructing an exact duplicate genome by chance are still vanishingly small.
And even identical twins don’t necessarily have identical DNA. Stray cosmic rays and chemicals in our diet, such as caffeine and nicotine, can cause point mutations in random genes, here and there.
