Grandson has 25% chance to inherit genes from his grandfather. so he has 50% chance to be carrier.

is it for all types of inheritence..AD,AR,XD,XR..?
Aa--------AA(1st generation)
Aa-----------(2nd generation)
AA(third generation)...how does the probability flow..first will have 25%,2nd will have 50%,third will have 75%?????
kaplan says grand father=1/2
father=1/4
grand son=1/8????

It's for autosomal recessive.
If We calculate from grandfather generation, the probability of this generation is always=100%
If grandfather = 1/2, there will be generations above grandfather (grand-grandfather)
