Evolution of chromosome number
Fissions
Gene trafficking
Birth of new genes
Exon Shuffling
Fusions
Horizontal gene transfer
Deletion

1. Evolution of chromosome number - fusion, deletion

2. gene trafficking - horizontal gene transfer, exon shuffling, birth of new genes

3. birth of new gene - exon shuffling, fusion and fission.

Explanation:

Evolution of chromosome number occurs due to the fusion and deletion of the chromosomes. Chromosome fusion may result in the speciation and isolation that rise the evolution in chromosome number.

Gene trafficking is the case that is arise due to various reasons such as forming new genes, horizontal gene transfer, and exon shuffling. However the birth of the new gene can be also arise by the fission and fusion and exon shuffling.

thus, the correct answer is - 1. Evolution of chromosome number - fusion, deletion

2. gene trafficking - horizontal gene transfer, exon shuffling, birth of new genes

3. birth of new gene - exon shuffling, fusion and fission.

the backbone of the dna and rna compound is sugar phosphate.

if the type of the food available changes, then the frequency of beak types will change, because birds with beaks more suited to the available food will be more successful over time.
