A biological process that directly contributes to the process of producing new individuals by one or two organisms. The new individuals inherit some proportion of their genetic material from the parent or parents. Construction of the chorion portion of the eggshell, which comprises the channels for gas exchange in an insect eggshell. Amplification by up to 60-fold of the loci containing the chorion gene clusters. Amplification is necessary for the rapid synthesis of chorion proteins by the follicle cells, and occurs by repeated firing of one or more origins located within each gene cluster. A developmental process by which a progressive change in the state of some part of an organism specifically contributes to its ability to form offspring. A biological process whose specific outcome is the progression of an integrated living unit: an anatomical structure (which may be a subcellular structure, cell, tissue, or organ), or organism over time from an initial condition to a later condition. The cellular component assembly that is part of the initial shaping of the component during its developmental progression. The process that occurs during oogenesis involving the ovarian follicle cells, somatic cells which surround the germ cells of an ovary. An example of this is found in Drosophila melanogaster. The developmental process pertaining to the initial formation of an anatomical structure from unspecified parts. This process begins with the specific processes that contribute to the appearance of the discrete structure and ends when the structural rudiment is recognizable. An anatomical structure is any biological entity that occupies space and is distinguished from its surroundings. Anatomical structures can be macroscopic such as a carpel, or microscopic such as an acrosome. The aggregation, arrangement and bonding together of a cellular component. Construction of the eggshell, a product of the somatic follicle cell epithelium and a structure that supports the egg in a hostile environment, minimizing water loss whilst allowing gas exchanges essential for embryonic respiration. The process by which cellular structures, including whole cells or cell parts, are generated and organized. Morphogenesis pertains to the creation of form. Establishment of the micropyle, a single cone-shaped specialization of the chorion that allows sperm entry into the egg prior to fertilization. The construction of a chorion-containing eggshell. An example of this is found in Drosophila melanogaster. Establishment of the dorsal filaments, elaborate specializations of the chorion that protrude from the anterior end of the egg and facilitate embryonic respiration.
