Meiosis I - Significance

Description:

The significances of the stage of Meiosis I are as follows −

• It involves disjunction and reduces the chromosome number.
• Chromosomal and genomic mutation may occur due to non-disjunction.
• Recombination of genes occur and so variations are produced due to crossing over.
• There is random distribution of paternal and maternal chromosomes into daughter cells.
• Due to disturbance in disjunction, chromosomal and genomatic mutation take place.
• Meiosis I induces the cells to form spores or gametes.
