A researcher finds genes which influence women’s motherhood choices
A group of Oxford researchers realized that women prefer having children in later stage in life despite strong will to reproduce when they are young. The researchers studied DNA samples of 7000 women and reached the conclusion. The scientists were trying to understand the impact of role genetics over the age of reproduction of women. Its effect on the number of children was also studied. Women’s genetic makeup was analyzed by researchers.
The sample consisted of women, who attained motherhood at different ages. The DNA analysis pointed out around 15 percent age variation in first time mother and around 10 percent difference about the number of children. The studies conducted in this domain before mostly focus on the sociological dimension of the women’s choice. Oxford University’s Melinda Mills is highlighting biological origins of late motherhood. Many trends such as continuing education, better participation in economy and contraceptive options can be explained biologically in terms of women due to this research.
The researcher has been successful to link the genetic structure with age of mothers and number of children. The follow-up study will be out soon which will give detailed information about the genes which influence these choices. Mills has informed that there is no one specific gene but combined effect of many genetic components is leading to this trend. There are certain sets of genes which directly influence the fertility of a female. The less fertile female will take longer time to conceive and this may affect her personality and will to study.
