Mammals Choose Grandchildren's Sex

Ilnar Salakhiev/AP – For a lioness, the safest bet would be to have a girl cub, according to a new study that says mammals have the ability to select the gender of their offspring for the benefit of their species. With sons, a lioness could end up with zero grandcubs or hit the genetic jackpot.

The bond between the Grandparent and Grand children is unique.

While certain naughty behaviour from sons and daughters were frowned upon, are overlooked in the case of Grandparents.

It is well-known that Grandchildren bond better with their Grand parents.

They have more liberty with their grandparents,share their intimate details with them, which the would not share with even their parents.

I have seen that Grandchildren ,in general, share physiological emotional and mental characteristics f Grand parents.

Tamil language calls he Grandchildren as ‘peran’, ‘The one who establishes Grandparents’ name.(பேரன்)

Now it transpires that Mammals choose the Sex of their grand children, a Study reveals!

Story:

Mammals appear to have the ability to select the gender of their offspring for the benefit of their species, according to a new study that followed three generations of more than 2,300 animals from the San Diego Zoo.

It is not a conscious choice, but in some way, a female’s biology has the capability to assess her health, the quality of her mate, and her environment to determine which sex to go with, according to study author and Stanford evolutionary biologist Joseph P. Garner.

For a lioness, for example, the safest bet would be to have a girl. Even if her daughter isn’t the strongest or highest-ranking female, she will most likely have at least the average number of cubs.

Sons, on the other hand, are a high-risk but potentially high-reward bet. Most male lions don’t reproduce because they are beat out by the few alpha males that father the vast majority of cubs. With sons, she could end up with zero grandcubs, or hit the genetic jackpot.”

There are also indications in the study as to why the initial Human Society was Matrilinear , the preference for female offspring instead of male.
