Definition
The term 'uniovular' refers to something derived from a single ovum, or egg. Think of it primarily in biology, particularly when discussing twins. Uniovular twins, also known as identical twins, originate from one fertilized egg that splits into two. Thus, they share nearly identical genetic material. This contrasts with fraternal twins, which develop from two separate eggs fertilized by two different sperm. Uniovular twins are always the same sex and share similar physical traits. It's like a cell dividing perfectly to make two of the same thing.
