Question

Write a paragraph explaining the sequence of events from gamete formation (meiosis), through fertilization, and development (including mitosis and differentiation). Describe/define and explain each event and why you sequenced it the way you did. Include text evidence and analysis. Next, you may add a sequence line/list summarizing the order of these 4 events outlined above....... Help!!!!!

Answer 1

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.
