Question

How is crossing over different than simply receiving a particular allele from each parent?

Answer 1

Crossing-over involves the exchange of genetic material between non-sister chromatids of homologous chromosomes during meiosis, leading to unique combinations of genes and increased genetic variation. Simply receiving a particular allele from each parent does not involve this exchange.

Step-by-step explanation:

Crossing-over occurs during prophase I of meiosis and involves the exchange of genetic material between non-sister chromatids of homologous chromosomes. This process, also known as recombination, creates unique combinations of genes and increases genetic variation.

Simply receiving a particular allele from each parent does not involve the exchange of genetic material. Instead, it results in the inheritance of specific alleles from each parent, which determines traits like blood type.

Answer 2

Crossing over gives the offspring sort of a genetic variation twist. This will mix our two genes and make them diverse, but together.
