Scenerio #5
Punnet square in action!
We are crossing two flies together.
Both parents are heterozygous long winged flies
At first I thought they would all turn out heterozygous but I was wrong. Instead they turned out with a ratio of 1:2:1 meaning; that if there was 100 flies bred together in this manner that 25 of them would be (GG) or homozygous dominant, 50 of them would be (Gg) or heterozygous and the last 25 would be (gg) homozygous recessive. it is amazing to see all the possible scenerios that can be combined using the punnet squares.
