Explanation
During meiosis, specifically in the first division (meiosis I), spindle fibres are formed to separate homologous chromosomes. However, in some special cases like meiosis in certain organisms, spindle fibres may not be prominent or absent. Generally, spindle fibres are crucial for chromosome separation during cell division.
