Question

fill in the blank question
if the cells of the morula separate, two embryos will be present instead of one, which will result in the formation of twins.

Explanation:

When the cells of the morula (an early - stage embryo) separate, the two resulting embryos are genetically identical. This is the characteristic of monozygotic twins. Dizygotic twins occur when two separate eggs are fertilized by two separate sperm. Since the separation of morula cells leads to a single - zygote (the morula is derived from a single zygote) splitting into two embryos, it is monozygotic.

Answer:

monozygotic
