16 Questions
What happens during the maternal to zygotic transition?
Switch from using maternal (egg) mRNA to zygotic mRNA
Why is blastocyst stage preferred over morula stage for IVF success?
Mitotic checkpoints are active at blastocyst stage
What do trophoblasts develop into?
Placenta
What marks the beginning of the formation of the placenta?
Hatching of the blastocyst out of the zona pellucida
