Extensive analysis of data from over 450,000 European women has yielded fascinating insights into the effects of the V660L variant. Carriers of this genetic trait experience fewer early-pregnancy bleedings, which helps stabilize early pregnancy. This reduction in complications enhances the likelihood of a successful pregnancy.
Women with this variant tend to have lower miscarriage rates, leading to a higher overall fertility rate. Studies indicate that these women have more children and siblings, suggesting that this genetic legacy improves reproductive success.
These advantages suggest that the variant was favored by natural selection. The ongoing prevalence of the V660L variant is a testament to its reproductive benefits through the ages.
