A gene is a small section of DNA?<span> that contains the instructions for a </span>specific<span>molecule, usually a </span>protein?. The purpose of genes?<span> is to store information. Each gene contains the information required to build </span>specific proteins<span> needed in an</span>organism<span>.</span>
Invasive species can destroy the ecosystem of the area it invades. This can be done by overpopulating and then destroying the environment of the land they invaded. It can also be done by killing or scaring off the native population.
Hope this Helps! :)
Answer:
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.
