Understanding the Genetics of HHT
... Since individuals with HHT actually have two copies of the “HHT gene”—one normal and one abnormal— each of their children has a 50% (1/2) chance of having HHT. This is because each egg and sperm has only one copy of each gene pair, not both. But whether it is the normal or abnormal copy of the HHT g ...
