Inheritances in health

Every family seems to inherit a lot from their elders, especially when it comes to health, and more specifically ill health and allergies.
My sister has completely taken over from mom. She has the slight wheezing/ skin ailments that mom has, and it has been there as long as i can remember.
I had exhibited all possibilities of inheriting all the unwanted stuff from dad. My systems are all screwed up starting from neck to the top( the brain is not included). Tonsilitis( from dad), blocked nose if i as much stand before an A/C( from dad?) and all associated stuff. These are from age 5 , so the family is kind of used to the fact that i am sneezing away to glory most of the year, and my sister is heavily moisturizing her ankles, even in monsoon.
For the last one year , a new phenomenon has started, i wake up with an arbid blocked nose, that transpires into a heavy throat pain, and my voice changes-sometimes i even sound like TB- and in about three days, lose my voice completely.
Not nice at all, considering that-
-I love talking.
-My job involves talking, most of the day.
- I love singing along with the radio.
- The doc seems to have no idea why this happens- she suspects allergy!

Allergy? WTH, where did this come from?
" Family...please raise your hands those who have contributed this one to my genes"

PS: V seems to be inheriting his mothers legacy as of now...
-he gets a cold sitting with the car A/C on.
-has been treated with asthalin on three occassions in his four years of existence.
- that dark patch on his ankle may turn out to be rough skin( god forbid!)
Maybe i should end the list here.Period!
