How many siblings have the same father and mother in the world?

Female: On July 22, 1971, Dr. Montanin, an Italian obstetrician and gynecologist, dissected 10 women and 5 men from the uterus of a 35-year-old woman, counting 15 fetuses, but all of them did not survive. On April 20, 1964, a Brazilian peasant woman named Sadalo gave birth to eight boys and two girls, making a total of 10 children.

The 10 siblings are all lively and healthy, and all of them are now over 30 years old and have started families. On November 15, 1994, Doris McDoan, a woman from Rhode Island, USA, gave birth to 17 babies in one child, setting a new world record for the most births in one child. Of the 17 babies, 12 were boys and 5 were girls.

Another fertility giant included in the Guinness Book of World Records was Vasilyev, a Russian woman in the 18th century, who gave birth 27 times, of which 16 were twins, 7 triplets, and 4 quadruplets (none of them were singles), a total of 69 children, becoming the most fertile woman in human history. M: King Ismail of Morocco was one of the most prominent emperors in Moroccan history, he reigned for 55 years (1672-1727), and his civil and military prowess was outstanding, but his fertility was even more impressive.

He had a total of 525 sons and 342 daughters, and is listed in the Guinness Book of World Records as the most fertile man in human history. One of the most recent fertility giants is Saudi Arabia's founding monarch, Ibn Saud (reigned 1932-1953), who married more than 300 times and had more than 160 children at the time of his death. It is clearly recorded in Chinese history that the person who had the most children was Liu Sheng, the king of Zhongshan Jing in the Western Han Dynasty, who was the son of Liu Qi, Emperor Jing of the Han Dynasty and the brother of Liu Che, Emperor Wu of the Han Dynasty, and gave birth to more than 120 sons in total (the number of daughters is unknown).

Liu Bei, the founding monarch of the Shu Han Dynasty, is his direct descendant. The surname "Liu" was still a very rare surname when Liu Bang established the Han Dynasty, but after more than 400 years of development of the Han Dynasty, it has become one of the few major surnames in China, and Liu Sheng has made great contributions to this. Another person in Chinese history who gave birth to more than 100 children was Zhu Jixuan, the king of Qingcheng in the Ming Dynasty, who was a descendant of Zhu Li, the third son of Taizu of the Ming Dynasty, and had about 100 sons.

Because there are too many sons, many of them don't know each other.

It's ......It's hard to say. Anyway, there are tens of millions, right?
