Which is the best definition for a recessive trait?

• only one form of the gene will be physically represented in the individual; will mask the other form of the gene; always expressed in offspring

• the unexpressed (masked by dominant) allele or trait; still part of the genetic makeup of the individual and can be passed on in successive generations if it becomes homozygous
