WebS is the period of DNA synthesis, where cells replicate their chromosomes. G2 is the period between the end of DNA replication and the start of cell division. Cells check to make sure DNA replication has successfully completed, and make any necessary repairs. M is the actual period of cell division, consisting of prophase, metaphase, anaphase ... WebSep 9, 2024 · Tetrad consist of two homologous chromosomes, each with two chromatids. Thus, a tetrad consists of 4 chromatids, two of which belong to each chromosome called …
WebCorrect option is C) The meiosis occurs in two stages meiosis I and meiosis II. Meiosis I is characterised by the pairing of homologous chromosomes, crossing over between homologous chromosomes and separation of homologous chromosomes, so that each daughter cell produced after meiosis I have one-half the chromosome number as …
WebMeiosis is a process where germ cells divide to produce gametes, such as sperm and egg cells. In prophase I of meiosis, chromosomes condense and homologous recombination takes place, leading to genetic variation through chromosomal crossover. This forms a tetrad, which is made up of four chromatids (two sister chromatids per chromosome). inm loc oaklandWebEvery cell of the multicellular offspring has copies of the original two sets of homologous chromosomes.
