Explanation:
The unfertilized egg contains various organelles and a liquid solution that fills the cell which is called the cytoplasm
Within that cytoplasm are various molecules containing genetic information or chemicals to spark various reactions, called cytoplasmic determinants
Some are different kinds of proteins, most are molecules of RNA and these determinants are unevenly distributed across the egg and then, once it's fertilized, the zygote
Once this zygote undergoes cleavage division, all of these random determinants that were in the same cell are suddenly in different blastomere cells, which means that these blastomeres each contain a different assortment of molecules
