The chromosomes of offspring are not identical to those of their parents or siblings because ______ is shuffled during meiosis.
tigry1 [53]

The chromosomes of offspring are not identical to those of their parents or siblings because <u>genetic information</u> is shuffled during meiosis.

Meiosis can be described as a cell division process by which gamete cells divide. The number of chromosomes is reduced to half in this cell division process.

During the process of meiosis, genetic information is shuffled between non-sister chromatids of the homologous chromosomes. This shuffling process is referred to as crossing over. A new combination of alleles is formed due to the process of crossing over.

It is due to the process of crossing over that the organisms produced are not identical to each other or the parents. Genetic diversity is important in order for populations to survive which is possible through the process of meiosis.
