I can't believe it's not autosomal dominant!
If it's autosomal dominant then the chance of an affected person transmitting the disease is 50% each time they have a child. So between them Indrakshi and Bhadraksh have had 12 children none of whom were affected. The chance of this is (½)12 which is one in 4096. Unlikely!
Also, should not at least one of the parents of Tarak and Surupa have been affected?

You must question the mode of inheritance. |

OK, I no longer believe that this is autosomal dominant. It's probably autosomal dominant with reduced penetrance. |  |
|
OK, It's clearly not autosomal dominant. I now believe that it's autosomal recessive. | |
