Sevva Thosham and Science

At home! Had a good day today. Went to the Shiva Temple as it was Pradosha Viradham today. Apparently, it was yesterday in London and today in Sri Lanka. I had no idea why and when people fast for Pradosham. I only had a slightest idea that it is something like Ekadasi. I got a good opportunity to talk to the priest there about religion, which is quite rare and unusual! I always get questions of why, what and how. And it was a time for me to ask some of the Whys I had in my mind though not everything. It is really amazing how science overlaps religion (in general). There is always a strong scientific aspect behind every feature of Hinduism. It was a delight to sit and listen to the priest about the religion and its science.

One of the interesting things I got to know was about the Sevvai Thosham. I did not know much about Sevva Thosham before as there was never a talk about it in my family. As the priest explained, a girl with Sevvai Thosham should marry a man with the same thosham. And that is because of the RH factor in the blood group. RH stands for Rhesus factor.
Everybody is born with a specific blood group with an RH factor being either negative or positive.
Basically, those with RH Negative are said to be Sevva Thosham and they should marry someone who also possesses RH Negative. This is because if the mother is RH negative and the father is RH positive, during pregnancy the mother will be exposed to the child's RH positive. Exposure to the RH positive will cause the mother's body's immune system to make antibodies against it and this may lead to the antibodies destroying the child's red blood cells or may cause severe problems. But if both the mother and the father is RH negative, the offspring will only be RH negative and therefore no harm.
Therefore, those with RH-Negative (Sevva thosham) should marry someone who is also RH-Negative (Sevva Thosham).
Hope this was not confusing :)

Female feticide and Sex ratio in India - BMJ

While leafing through the BMJ magazine; June, a letter on one of the articles of sBMJ May urged me to find the May issue and read it. It was about the unwelcome sex in India. I have heard about the high occurrence of female feticide in India but happening to hear a lot in the recent days on magazines and blogs.

The article touched on the dangerous traditions in India which favour for the birth of a boy than girl as boys are cheaper because of the dowry system. The high social and economic value of men is the causation for sex selective abortions in India. Though the dowry payments are illegal, it is accepted as a tradition to continue their family hierarchy and this phenomena is deeply rooted in the societies. Although is illegal to do a prenatal examinations to identify the sex of a fetus is illegal in India, if the families once known it is a girl, the fetus is terminated. According to the article, evidently there were about 5 million female fetuses are aborted every year purely on …
