In a haplontic life cycle, the adult multicellular organism is haploid, which means it has only one set of chromosomes. The time spent between fertilization and meiosis is shorter than the time spent between meiosis and fertilization because after fertilization, there is only mitotic division, which results in the growth of a multicellular haploid individual. Meiosis occurs only during gamete formation, which happens at the end of the haploid phase. Therefore, the time spent between meiosis and fertilization is longer.
