Then, we inferred the original heteroplasmy levels in the fertilized egg of HetFEvariants. Notably, we observed that the average clone-VAF value of a HetFEvariant across all clones from a donor (referred to as
In humans, early investigations by light microscopy found that hPGCs have a large size with a large nucleus and prominent nucleolus in the yolk-sac endoderm of embryonic day 24 (E24), which migrated into the developing genital ridges at E28.14Witschi suggested that the hPGCs migrated within the...
Gametes are produced by meiosis rather than mitosis because a. meiosis doubles the chromosome number so that each gamete has twice the usual number of genes. b. meiosis ensures that the gametes are identical to the cell that produced ...
Figure 2.The sMics are dispersible for development but are required for gamete development. (A) Method of sMic removal with a glass pipette. The resulting embryos develop into a larva (B)–(E), form an adult rudiment (D, E, arrow in E), and metamorphos into an adult (F) that does...
A broad review of comparative aspects of germ cell formation will not be attempted (see 78, 79, 1 for general reviews). Most is known of the genes that control germ cell formation from systematic genetic screens in invertebrates. In Drosophila and C. elegans, maternal effect mutations, in wh...

If collisions were not resolved at the time of egg chamber individualization, then this would lead to the formation of a compound egg chamber containing two cysts packaged together. In chic-RNAi and zip-RNAi, we also noticed that cysts in region 3, instead of being round, adopted an ...
a cause of 4th chromosome decreased expression, there must be a gain of inactivation during the developmental transition from mitotic spermatogonia to meiotic spermatocytes. This X chromosome like behavior may reflect the evolutionary history of the 4th chromosome; specifically, that the 4th retained X...
