WebAug 21, 2024 · Zygotic Genome Activation in Vertebrates. The first major developmental transition in vertebrate embryos is the maternal-to-zygotic transition (MZT) when maternal mRNAs are degraded and zygotic transcription begins. During the MZT, the embryo takes charge of gene expression to control cell differentiation and further development. Webfertilization rate should be ≥50%. In case of fish spawning for the first time, fertilization rates may be lower in the first few spawns. Egg differentiation 15.
