LDS belief in pre-existence of the human person vs. human physical deformities

This other question discusses the Mormon doctrine of pre-existence prior to conception. The highest rated answer quotes from The Encyclopedia of Mormonism that says, on the page "Pre-Existence (Pre-Earthly Existence) " that (emphasis added): > It is Latter-day Saint doctrine that living things existed as > individual spirit beings and possessed varying degrees of intelligence > in an active, conscious spirit state before mortal birth and that the > spirit continues to live and function in the mortal body. **The > revelations teach that premortal spirit bodies have general > resemblance to their physical counterparts.** I wanted to ask some questions about the part that the "premortal spirit bodies have general resemblance to their physical counterparts" (to get an understanding of the reasoning behind this): 1. When it comes to people born with physical deformities (weirdly shaped limbs, missing body parts, both male and female genitalia, etc.), are these deformities then also present on that persons spirit body? 2. If they are present in their spirit body, why would that be the case? (i.e. shouldn't the spirit body be created perfect or is there some reason why it would not be?) 3. If they are **not** present on the spirit body, why would they be on the physical body if there is an expectation of general resemblance between these two?
