Final answer:
The false statement about meiosis is that tetrads are visible until anaphase II; instead, they are visible during prophase I of meiosis and separated during anaphase I.
Step-by-step explanation:
The statement that all of the following concerning meiosis are true except "B) tetrads are visible until anaphase II" is the correct answer. This statement is incorrect because tetrads, which consist of four chromatids (two homologous chromosomes), form during prophase I of meiosis and are separated during anaphase I, not anaphase II. Anaphase II concerns the separation of sister chromatids, not tetrads. Therefore, the correct answer highlighting the false statement about meiosis is B.
Meiosis converts diploid cells into haploid cells, occurs in two phases known as meiosis I and meiosis II, and begins after DNA replication during interphase. Genetic variety originates from the process of crossing over that occurs in meiosis I.
