WebApr 13, 2024 · In some animals, like Drosophila, Xenopus, and zebrafish, germ granules form during oogenesis from maternally expressed proteins and RNAs. During early embryogenesis, these maternally supplied granules are segregated to a subset of cells that will give rise to the germline. WebGerm-line mutations occur in reproductive cells (sperm or eggs) and are passed to an organism’s offspring during sexual reproduction. Somatic mutations occur in non-reproductive cells; they...
