Match the followings causes with their effects. Connect each cause against its appropriate effect through a line to match. Drag a line from each term to the corresponding description. Note that one cause may have multiple effects.

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.
