homozygous recessive, what would be the expected percentage of offspring that will get Huntington's disease?
-
Simple punnett square here.
H h
h Hh hh
h Hh hh
Therefore 50%. You could simplify the square futher by only using one line for the recessive person as the results would be the same.
H h
h Hh hh
h Hh hh
Therefore 50%. You could simplify the square futher by only using one line for the recessive person as the results would be the same.

50%. The heterozygote is Hh, and the homozygote is hh. The Punnett square is:
_____h____
H___Hh____←50% have Huntington's
h___hh____←50% do not
_____h____
H___Hh____←50% have Huntington's
h___hh____←50% do not
