Meiosis makes each new cell genetically unique in terms of DNA. This ensures that the offspring of the organism is also genetically unique as the two gametes (sex cells) combine together to give the cell a full set of chromosomes that the cell needs to divide/multiply into a new life.
The order would be: Meiosis -> sex cells -> fertilization -> zygote -> mitosis Meiosis creates sex cells, called gametes, which combine during fertilization to create a zygote. The zygote then undergoes mitosis.
The steps in the diploid life cycle are meiosis, to gametes, to fertilization, to diploid, to reproductive cell. The main steps are Meiosis and Fertilization.

Yes, meiosis is necessary before fertilization can occur because meiosis is the process by which gametes (eggs and sperm) are formed. During meiosis, the cell's chromosome number is halved, so that when the egg and sperm fuse during fertilization, the resulting zygote will have the correct number of chromosomes.

Yes, sexual life cycles can differ based on the relative timing of meiosis and fertilization. In some organisms, such as animals, meiosis and fertilization occur separately and alternately, resulting in a diploid-dominant life cycle. In contrast, in some algae and fungi, meiosis and fertilization can occur in close succession, leading to a haploid-dominant life cycle.
In plants, meiosis occurs in the reproductive organs known as the anthers (in male parts) and ovules (in female parts). Fertilization, where the male gamete fuses with the female gamete to form a zygote, typically occurs in the ovules.
A diploid organism is formed during fertilization when a haploid sperm cell fertilizes a haploid egg cell to create a zygote with a complete set of chromosomes. Meiosis is the process that produces haploid gametes (sperm and eggs) in preparation for fertilization.
A secondary oocyte will complete meiosis II after fertilization by a sperm cell.
Meiosis is the process by which gametes (sperm and egg cells) are produced, halving the number of chromosomes. Fertilization is the fusion of a sperm cell with an egg cell to form a zygote with a complete set of chromosomes. Together, meiosis and fertilization ensure genetic diversity in offspring by creating new combinations of genes.
The development of a new progeny organism is then initiated by the fusion of these gametes at fertilization
At the end of meiosis, haploid cells are produced. These cells need to further develop into mature gametes capable of fertilization, a process called gametogenesis.
