I’d say you’re talking about how it came to be in the first place? My guess would be a mutation or improper allele. Otherwise, if both biological parents have two recessive alleles, they wouldn’t pass it on to their offspring.
@@elegantatrocity There's a famous bollywood actor, Hrithik Roshan that has polycactyly condition, has an extra thumb. But none of his parents have it. Is it possible? If so, how?
nSack “The vast majority of occurrences of polydactyly are sporadic, meaning that the condition occurs without an apparent cause - while some may be due to a genetic defect or underlying hereditary syndrome.” It can apparently happen without a known cause? I’m guessing scientists are still looking into it.
imagine if parents are Aa | Aa respectively, the polydactyly gene being recessive, there is a 25% or 1/4 chance of ofspring to be aa allele which means he has this condition. altho parent may not have the conditoon, the offspring may have it due to recessive gene. english not my first language so ignore me being trash at it :/

Hello, i can't find this on the aqa spec do you mind adding it?
I was born with 6 fingers on each hand from my pinky. It simply tired off when I was a baby.
My question is how can a child undergo Polydactyly condition when neither of his parents have Polydactyly.

Qualily I think polydactyly is a dominant condition. It’s the example of dominant I learned, and cystic fibrosis is an example of recessive.
Amazing video
2 of my sisters had polydactyly but me and my fist older sister didn't
ooooooo
thank you!!!!
thanks
IT'S POLYDACTYL
Polydacytly is autosomal or sex linked disorder?
oh ok nice nice
I don’t like the way you regard people without the inherited disorders as ‘normal’…
then how should he express that
how else are we supposed to know dumbass, we're here to revise not to argue about how people should be regarded.
Well they are normal
i literally went from the website to here to find a comment like this🤣🤣🤣
