Development and Alterations of Gametes and Chromosomes: A Comprehensive Study

This article provides a detailed comparison of mitosis and meiosis, analyzing the homologous chromosome pairs and their role in the human diploid chromosome number. It also explores chromosomal abnormalities, ovulation, fertilization, and the end result of fertilization. Furthermore, it delves into natural fertilization versus IVF, mitosis after fertilization, the stages of the zygote, and the formation of blastocyst and gastrula. Additionally, it covers topics such as placenta types and examples, as well as common complications like miscarriage.
