Answer:
The haploid gametes are formed by meiosis, a cellular process that involves two cell divisions and one round of DNA synthesis (i.e., four gametes with haploid DNA content). Subsequently, the gametes are fused during the fertilization to produce a diploid zygote. Finally, the zygote undergoes successive mitotic cell divisions where specific genes are expressed, this process enables the development of an embryo with different tissues and organs.
