Choose the correct statement about meiosis.
Choose the correct statement about meiosis.
The correct option is C Meiosis typically results in genetic variation among the gametes produced
Meiosis is important because it ensures that
all organisms produced via sexual reproduction contain the correct number of
chromosomes. Meiosis also produces genetic variation by way of the process of
recombination. During prophase of meiosis I, the double-chromatid homologous
pairs of chromosomes cross over with each other and often exchange chromosome
segments. This recombination creates genetic diversity by allowing genes from
each parent to intermix, resulting in chromosomes with a different genetic complement.Because
of recombination and independent assortment in meiosis, each gamete contains a
different set of DNA. This produces a
unique combination of genes resulting in zygote.
So,the correct option is 'D'.
