U.S. researchers said the gene that prolong the period of fertility for women are the same responsible for prolonging the lives of mothers who give birth at a later age.

A study published in the Journal of Gerontology that siblings born later in the mother's life live longer than others, indicating that the genes that prolong the lifespan of women is itself responsible for prolonging the period of fertility, may be more important than social and environmental factors.

He explained the charge of the study at the University of Utah, Ken Smith, that women who give birth at the age of 45 years less likely to die after the age of the fifties by 14 percent to 17 percent, compared with children who did not give birth after the age of forty.

"If the women in your families, give birth to advanced age, you have the opportunity to live for a longer period, if one Qribatkm and gave birth to a baby after the age of 45, there are some genetic benefits in the family that would prolong Aammarkm," he said.

The findings are based examinations of the genealogical records of the residents of the state of Utah Mormons, who number 1.6 million, and the data from the University of Montreal for a 400 Moazn lived in Quebec between 1608 and 1850.
