three of the terms are related. one term does not belong. determine the characteristic common to three of the terms and then identify the term that does not belong.
1. inversion, translocation, duplication, nondisjunction
2. operator, promoter, repressor, gene cluster
3. dominance, codominance, incomplete dominance, polygenic inheritance
4. gene mutation, point mutation, frameshift mutation, chromosomal mutation.

I happen to have my biology book with me.
1. duplication - The process of DNA coping itself inside the nucleus then seperating to become two different cells with exact copies of the parent DNA.
2. I know that it is gene cluster because it doesn't have anything to do with the other choices and it isn't in my book.
3. polygenic inheritance - a trait that is inheritated by multiple genes.
4. chromosomal mutation - a mutation in an entire chromosome not just one gene.

1.non disjunction is not a method of chromosomal mutation.
2.gene cluster -rest are part of operon system.
3.polygenic inheritance- rest are not accumulative.
4.frameshift -is a type of gene mutation

A novel idea, learn and do it yourself, try a little time looking around at homeworkspot.
