What does JUMP mean in this sentence?

Question

Sometime genes can jump several generations.
Does this mean that some genes can occur in my genetic material, but that this gene does not have my parents, my grandparents and parents of my grandparents. But that the gene for example had grandparents of my grandparents? If you understand me.

Thus several generations did not have this gene. But since I have had someone in the distant past.

Yes, but you mean that your grandparents didn't have the gene and someone in the past had the gene.

A person has a gene.
They had a gene.
You have a gene.

Jump does work in the context. Skip also works.

you might want to take this question to a biology forum.  someone can cary a gene without expressing it.  you may have the gene for blue eyes from your mother and the gene for brown eyes from your father, but you would only show one eye color.   If you were to have a child, the brown eye gene may be passed down even if you have blue eyes.     this brown eye gene could pass through multiple generations without showing at all.     that is what jump refers to, the ability of a gene to pass through multiple generations without being expressed.

vb5Thus several generations did not have this gene.

No. This is impossible; you can't have a gene which is missing in several generations and then suddenly shows up in the next generation.

The original statement, that genes can jump several generations, is not literally true. It's an idiomatic way of talking about gene expression. A gene can be unexpressed for several generations and then be expressed in a later generation, but the gene was being passed from one generation to another all the while, and all the generations in between had the gene. See previous answer.
