Hardy Weinberg Model Question(click for details)?
Why are certain harmful traits dominant, yet they aren't seen in public??
i think its because they are only shown in one sex, appear later in life, or the organism (that has it) does not survive (like in case 3 in my lab)
case three if we had AA, we needed to flip a coin to see if we survived or not, then if we didn't survive we mated again for the same person, if we survived-we were able to keep AA.
please help me, i just want to know if I'm right, and if not, what is the right answer??
Thank you!

In general, you're right in most cases, but you're missing one reason that some dominant traits are rare: the alleles that cause them are rare in the gene pool. We don't see examples of dominant traits like widow's peak, polydactyly, or Huntington's Disease very often because alleles that cause those are not very common.
