Answer 1

hey mate how are you here is your answer ☺☺

In biology, a mutation is a alliteration of the nucleotide sequence of the genome of an organism virus or extrachromosomal DNA.

#chromosomal mutations that affectwhole genes on chromosomes :4 types1)Duplication2)Deletion3)Inversion4)Translocationchanges in chromosomes structure include:Translocations.A translocation occurs when a piece of one chromosome. This type of rearrangement is described as balanced if no genetic material is gained or lost in the cell

hope its help you if you want this answer is correct for you then plz mark me as a brainlist if you want
