胚胎学家通常对卵子发生感兴趣，因为他们意识到早期胚胎中的细胞所做的许多决定反映了受精前卵子中以某种形式存在的决定因素的分布。这使我们可以将为什么胚皮不同区域具有不同胚胎命运的问题简化为两个子问题：(1)卵细胞质的不同区域如何变得彼此不同？(2)单个胚皮细胞在选择其特定命运时，如何解释这些初始细胞质差异？
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?
