The pairing of homologous chromosomes during prophase 1 lets the crossing over to occur and crossing over between non-sister chromatids, in turn, lets the recombination to occur. Crossing over occurs at points called chiasma, which are created between non-sister chromatids. Chiasma lets the exchange of DNA segments between non-sister chromatids. This exchange of DNA segments produces new combinations of alleles among the offspring, which is identified as genetic recombination.

First thing to clarify is that MVP is not an architectural pattern, itâs only responsible for the presentation layer.
