Why is crossing over so important to a species?

Answer 1

Crossing over is important for variations.

The crossing over is an important event in the pachytene of meiosis-1. It helps in the process of recombination of genes. The recombine genes produce variations in the species. The variations in the species leads to the 'natural selection' from the suitable organisms. Thank you

Crossing over is important to a species because it increases genetic diversity by shuffling genetic material between homologous chromosomes during meiosis. This process generates new combinations of alleles, leading to offspring with unique genetic traits. Increased genetic diversity enhances a species' ability to adapt to changing environments and increases its overall evolutionary fitness.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
