Colombia/New Delhi: Miracles of nature are often beyond human understanding, but the case that has come to light from Colombia, South America, has shocked the modern science and medical world. Here a woman gave birth to two twins, but when their DNA test was done, the scientists were shocked to see the results. Investigation revealed that both the children have the same mother, but their fathers are two different men.
How was this ‘scientific’ secret of two fathers revealed?
This matter came to light when the woman reached Colombia’s ‘National University’s Laboratory of Population Genetics and Identification’ to get the paternity test done for her two-year-old twin sons. scientists have ‘Microsatellite marker’ A technique was used in which small pieces of DNA are compared. When 15 to 22 points were examined, it was found that one child’s DNA matched that of the alleged father, while the other had a completely different profile. The director of the lab, who has been managing this institute for the last 26 years, said that he had never seen such a rare case before in his career.
What is ‘heteropaternal superfecundation’?
In the language of science this rare condition Heteropaternal Superfecundation It is said. According to a BBC report, only 20 official cases have been registered so far across the world. In a research conducted in Baltimore, USA, only 3 such cases were found out of a database of 39,000 paternity tests, which shows its rarity.
How is it possible to have two different fathers together?
According to experts, this phenomenon is possible only when two rare conditions occur simultaneously during the same menstrual cycle:
Polyovulation: Normally a woman’s body produces only one egg in a month, but in this case two or more eggs are released during the same cycle.
Two companions in a short time: If a woman has sex with two different men within a very short period of time, different sperm can fertilize both eggs.
Do these kids look alike?
Scientists have clarified that these twins born from different fathers can never ‘Identical Twins’ Can’t be (look alike). This is because identical twins are always formed by the division of the same egg and the same sperm. Children born in this case come under the category of ‘Fraternal Twins’, whose genetic makeup is different like that of ordinary brothers and sisters.
