What is 0 %.

Why would you think that Dominant Genetic Disorders are rare?
What is... The chances of the genetic disorder being passed on is rare because the subject is usually unable to reproduce or wouldn't breed with someone who carries that allele. Other answers may apply.

What is a Dominant Trait?
Bb and Bb breed. What is the probability of a homozygous recessive offspring?
What is 25% ?

Ff
If a Mother and Father both were carriers for TSD (Tay-Sachs Disease), why does only 1 of their 4 children have TSD?
