Rainbow trout go through a unique genetic reproductive process. Female eggs are diploid, while male sperm are haploid. In the wild, when the sperm fertilizes an egg, the extra set of chromosomes is eliminated, resulting in a diploid offspring. The process that produces the sperm and egg, and the process the offspring use to grow into adults are, respectively,
1) Process to produce sperm and egg: Meiosis, Process used for growth of the offspring: Cytokinesis
2) Process to produce sperm and egg: Mitosis, Process used for growth of the offspring: Cytokinesis
3) Process to produce sperm and egg: Meiosis, Process used for growth of the offspring: Mitosis
4) Process to produce sperm and egg: Mitosis, Process used for growth of the offspring: Meiosis
