Answer;

B. organelles

Explanation;

  • Eggs contribute 50% of the chromosomes as well as cytoplasm and cellular mechanisms required for the cell to thrive and replicate.
  • Mitochondria for example are particularly important to the embryo but are only passed from mother to child via the egg.
  • Sperms on the other hand, are just packets of DNA.
