Which of the following is a complete list of the main types of chromosomal mutations? (a) inversion, duplication, insertion, translocation (b) deletion, duplication, inversion, translocation (c) deletion l, duplication l, inversion, translocation (d) inversion, translocation, substitution l, insertion

The complete list of the four main types of chromosomal mutations is shown in the option: (b) deletion, duplication, inversion, translocation. During the deletion the chromosome loses its genetic material. Duplication is when a particular portion of the chromosome is replicated and copied. Inversion means that the order of  the genetic material is switched. And when a piece of one chromosome breaks off - translocation occurs.

Yes yes yes very good
