What does this tell you about maternal versus zygotic gene activity in early fro

Actinomycin D is a drug that inhibits the activity of RNA polymerase II. In the presence of actinomycin D, early development in many vertebrate species, such as frogs, can proceed past the formation of a blastula, a hollow ball of cells that forms after early cleavage divisions; but development ceases before gastrulation.

What does this tell you about maternal versus zygotic gene activity in early frog development?
Check all that apply.
    -Development beyond the gastrulation must be largely under control of maternal effect genes.
    -Development from fertilization until gastrulation must be largely under control of maternal effect genes.
    -Zygotic gene expression must be largely under control of maternal effect genes.
    -Zygotic gene expression is required for gastrulation and beyond.

Zygotic gene expression is required for gastrulation and beyond.
