PLZ HELP ME!! There is a genetic trait called sun sneezing when sufferers from ACHOO syndrome sneeze uncontrollably when exposed to direct sunlight. The allele that causes sun sneezing is dominant over the non-sneezing allele. A sun-sneezing man marries a non-sneezing woman. They have many many children and all are sun sneezers.

i think its the first one
