Verified step by step guidance1
Understand the types of chromosomal mutations listed: chromosomal inversion, gene duplication, silent mutation, and translocation.
Chromosomal inversion involves a segment of a chromosome being reversed end to end. This can affect gene expression but does not typically result in a silent mutation.
Gene duplication results in extra copies of genes, which can lead to increased gene expression or new functions, but not a silent mutation.
Silent mutations occur at the nucleotide level and do not change the amino acid sequence of a protein. They are less likely to result from large-scale chromosomal mutations.
Translocation involves the rearrangement of parts between nonhomologous chromosomes, which can disrupt gene function but does not typically result in a silent mutation.
