Hi my name is John Dooley from The UK aged 16.
At the momment for homework one of the questions is all about the
Drosophila flies, and to my astonishment there is a huge web site all about
it, well it is yours.
My question which confused me is this:

were bred together and had 200 offspring, about how many would have the
Of these offspring some will be homozygous dominant and some hetrozygous.
How is it possible to establish which is which?
