Question

Quizplus · Accepted Answer

Since Samantha is Stacey's monozygotic twin, they have identical DNA and therefore identical HLA (human leukocyte antigen) markers. HLA markers are used to match organ donors and recipients, and having identical HLA markers greatly increases the chances of a successful organ transplant. Therefore, Samantha would be the best match for Stacey.
