If you're talking about just the arm and just the leg (not including the ankles and wrists or elbows and knees. The amount of bones are the same.
Huntington's disease is a disease that inherited autosomal dominant. That means you just need one allele to made it expressed. Let say that H is Huntington's allele and N is normal allele. In this case, the heterozygous father has (H x N) gene and the normal mother has (N x N) gene.
That mean
1. The father will have 50% chance to give normal allele and 50% chance to give H allele
2. The mother will have 100% chance to give N allele
Since you just need 1 H allele to got Huntington's disease, 50% the children will have Huntington's while 50% of them is normal
