(2) Empirically, 1⁄4 of achondroplasia births are inherited and 3⁄4 are de novo.
sorry; point 2 again, (Aa x aa should product a 1⁄2 not a 1⁄4)
acondroplasia X normal
............A.............a
...a.......Aa..........aa
...a......Aa...........aa
50%Aa acondroplasia
50%aa normal
or am I confused somewhere? Is that not the punnet square?
Sure, that’s the punnet square. You should stop drawing punnet squares and ask yourself why you are drawing them and ask what role they play.
The number 1⁄4 is the empirical fitness. It is mainly about how many children dwarfs have. You cannot guess that number by looking at punnet squares.
