Explain how each of the following deviates from these conclusions. A new population was created by crossing 51 pure breeding homozygous dominant individuals with 49 pure breeding homozygous individuals.

The different results you would expect if a mutation occurred at the recognition site for enzyme Y. What would be the effects of a substitution in one of the nucleotides?
By using the techniques of genetic engineering, scientists are able to modify genetic materials so that a particular gene of interest from one cell can be incorporated into a different cell.
