Answer:
1) Crossing over
2) Independent assortment.
Explanation:
Gametes are formed resulting from the process of meiosis where the gametes get half of the original number of chromosomes. One phenomenon that happens during the prophase 1 of Meiosis and leads to the genetic diversification is crossing over. In this process , Here, homologous chromosomes pair up and exchange information present on genes from one another. When information is exchanged, it leads to the diversity of genetic data.
The second way of increasing genetic diversity is independent assortment that takes place during metaphase 1. In this process chromosomes from both father and mother cells align on equatorial plate of the cell in an independent manner. This means that some gamete can have 1 of many different chromosomal combinations.
This reshuffling of chromosomes during independent assortment enhances the genetic diversity of any organism and this also explains why kids of same parents can look or behave very different.

There is 4 adenine, cytosine, guanine, and thymine.
Answer:
c) It introduces a premature stop codon into the mRNA
Explanation:
Nonsense mutation is a type of point mutation (single nucleotide base is changed) which leads to premature stop codon. Stop codons are also called nonsense codons and that is way this type of mutation is called nonsense mutation. As a consequence, synthesized protein is incomplete and shorter than it should be (truncated protein), usually nonfunctional.
