Why Crossing over has been compared to shuffling the deck in cards.?

Crossing over during meiOSis is akin to shuffling a deck of cards because it mixes genetic material between homologous chromosomes, creating new combinations of alleles. Just as shuffling randomizes the order of cards, crossing over generates genetic diversity by rearranging inherited traits. This process ensures that offspring receive a unique set of genes, enhancing variation in a population, much like how a shuffled deck yields different hands each time it's dealt.
