The union of male and female gametes to form a zygote. A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of the nucleus. A process that is carried out at the cellular level that results in the assembly, arrangement of constituent parts, or disassembly of chromosomes, structures composed of a very long molecule of DNA and associated proteins that carries hereditary information. 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. Any process that is carried out at the cellular level, but not necessarily restricted to a single cell. For example, cell communication occurs among more than one cell, but occurs at the cellular level. Unwinding of the condensed nuclear chromatin of an inactive sperm nucleus. Replacement of sperm-specific chromosomal proteins with somatic histones, to allow the paternal genome to acquire a nucleosomal chromatin organization compatible with nuclear activity. A process, occurring at the cellular level, that is involved in the reproductive function of a multicellular or single-celled organism. Any process that results in the specification, formation or maintenance of the physical structure of eukaryotic chromatin. The aggregation, arrangement and bonding together of a set of components to form an organelle. An organelle is an organized structure of distinctive morphology and function. Includes the nucleus, mitochondria, plastids, vacuoles, vesicles, ribosomes and the cytoskeleton. Excludes the plasma membrane. The conversion at fertilization of the inactive sperm nucleus into a male pronucleus with its chromosomes processed for the first zygotic division.
