The tetrad is a structure that only exists during the late stages of Prophase I and early stages of Metaphase I in Mieosis I. Prior to being sent off to different cells, the h â¦ omologous chromosomes clump together in these units called tetrads consisting of 2 chromosomes and 4 chromatids. Corresponding parts of the 2 homologous chromosomes are able to switch with each other during this state in a process known as crossing over.
Best Answer: Zygote Formation and Development of the Embroyo Zygote Formation If sperm are present in the oviduct at the time of ovulation, fertilization takes place in the oviduct. Zygotes form as a result of fertilization.In fertilization, the egg nucleus (containing the haploid number, or n chromosomes) unites with the sperm nucleus (containing n chromosomes). This union produces a zygote of the original diploid or 2n chromosome number.t is formed when the Male and Female haploid cells-Gametes -, sperm and egg, join fertilising the egg and forming the Zygote. Haploid cells having half the normal number of Chromosomes, they have 23. Hugh D Morris Â· 7 years ago.
