| Description: In this simplified diagram, the mother's diploid nurse cells transfer gene products to the egg as it matures. These gene products persist after fertilization, affecting development of the early embryo. If the nurse cells are DD or Dd, they will transfer the dominant D gene product to the egg, causing the offspring to be dextral. If the nurse cells are dd, only the d gene product will be transferred to the egg and the offspring will be sinistral.
