Sagot :

Answer:

Explanation:

Crossing over and independent assortment in gametes (sex cells) can lead to genetic variation in the DNA of these gametes and lead to offspring looking different from their parents. Crossing over is the exchange of DNA between a pair of homologous chromsomes (the mom and the dad) which results in recombinant chromsomes that have new combinations of genes. Independent assortment refers to the lining up of chromsoomes along the metaphase plate in meiosis 1, and this can lead to different combinations of gametes.
