A Combined Genetic and Mosaic Approach to the Study of Oogenesis in Drosophila

  • Eric Wieschaus
Part of the Basic Life Sciences book series (BLSC, volume 16)


An embryologist usually becomes interested in oogenesis with the realization that many of the decisions made by the cells in the early embryos reflect a distribution of determinants present in some form already in the egg prior to fertilization. This allows us to reduce the question of why different regions of the blastoderm have different embryonic fates into two subquestions: (1) How do the different regions of the egg cytoplasm become different from each other? (2) How are these initial cytoplasmic differences interpreted by the individual blastoderm cells in choosing their particular fates?
