Which type of mutation affects the largest number of genes

Chromosomal mutation

Explanation:

Any modification that interferes with the number or structure of chromosomes in a cell is called a chromosomal mutation. Chromosomal mutations can be classified into numerical mutations, where there is change in the number of cell chromosomes, and structural mutations, where there is change in the shape or size of one or more cell chromosomes.

Numerical mutations are further subdivided into aneuploidies and euploidies. In aneuploidies, there is an increase or loss of one or more chromosomes; In euploidies, the increase or loss will be in complete chromosomal batches, also known as genomes.

prophase: we can observe the chromosomes to coil up and condense. they become visible. nuclear membrane and envelope disintigrate.s

metaphase: chromosomes align at the center, the metaphase plate. spindle fibers attach to centromeres of the sister chromatids. they meet at kinetochores.

anaphase: sister chromatids are pulled towards each opposing centromere, set on different poles.

telophase: chromosomes are now clustered up only on either sides of the cell. nuclear membranes reform, and a new cell wall forms along the cell plate. this will lead to cytokinesis, the process that divides the cell membrane and forms the cell wall.
