Which of the following sequences describes the general life cycle of a eukaryotic organism? a. 1N meiosis 2N fertilization 1N b.
ehidna [41]

Answer:

b. 2N meiosis 1N fertilization 2N

Explanation:

In eukaryotic organisms, gamete mother cells are diploid (2N) and have two complete sets of chromosomes. Meiosis in male and female gamete mother cells form haploid male and female gametes (N) respectively. This occurs since meiosis reduces the number of the chromosome to half in the daughter cells. The fusion of haploid male and female gametes during fertilization restores the diploid chromosome number of the species and forms diploid zygote (2N). Repeated mitotic divisions in the diploid zygote form the diploid organism.
