Two chromatids
WebReplication also known as duplication of chromosomes, forms identical strands of chromatids which later separate during cell division to form individual chromosomes. So, since there are 46 chromosomes in the human body, the number of chromatids is just the double of it – 92. Each chromosome therefore consists of two chromatids. WebThe stages of Mitosis are: Prophase – The chromosomes shorten and thicken. Metaphase – Chromosomes line up in the middle of the cell. Anaphase – Chromatids break apart at the …

WebCorrect option is A) The two replicated homologous chromosomes associate to form a bivalent. It is also known as tetrad and mainly formed during the pachytene stage of the meiosis. It consists of a pair of homologous chromosome, each with 2 sister chromatids (total of 4 chromatids) attached with one centromere (total of 2 centromeres) They ... WebS Phase: To produce two similar daughter cells, the complete DNA instructions in the cell must be duplicated.DNA replication occurs during this S (synthesis) phase.

WebIn summary, chromatids are the two copies of a chromosome that are formed during DNA replication and are visible during prophase. The presence of four chromatids is a characteristic of meiosis, a type of cell division that occurs in gamete-producing cells and results in the formation of four genetically diverse daughter cells.
