- At9:03, you talk about the non-uniform distribution of cytoplasmic determinants and how they get partitioned among daughter cells. This leads to different cells (or blastomeres) containing factors specific for different genes. In case of humans, even if a single blastomere is removed from the blastula, it could still give rise to a whole embryo. How is that possible if it doesn't have all the transcription factors?(5 votes)
- did you say this is the way it's done or this could be done?(3 votes)
