However, it can also break up "good" combinations of genes.
Even disorders caused by unknown combinations of genes may soon be better understood.
This shuffling is important for evolution because it can introduce new combinations of genes every generation.
That's because when organisms reproduce sexually, some genetic "shuffling" occurs, bringing together new combinations of genes.
You can imagine the varying fitness of different combinations of genes as a hilly landscape, in which the valleys represent less-fit combinations of genes and the peaks represent the fitter ones.
Different genetic variants contain different combinations of genes, which can be thought of as appearing on a single string.
CBS News reports that MIT engineers have identified several combinations of genes that make bacteria more vulnerable to antibiotics.
Our results show that multiple combinations of genes might bring about similar clinical pictures.
These swaps generate new combinations of genes and hence individuals that differ from their parents.
When the program goes off track, such as in autism, it is often because of combinations of genes that in other combinations would be fine.
sexual reproduction -- A type of reproduction in which two parents give rise to offspring that have unique combinations of genes inherited through the gametes of the two parents.
