Q. From a diploid condition of 2N, which condition can arise due to non-disjunction of chromosomes?

AMUAMU 1997

Solution:

: Non-disjunction of chromosomes is the phenomenon of failure of the separation of the
homologous chromosomes during meiosis I or the two sister chromatids of a chromosome during meiosis II. It leads to the change in the chromosome number.
