So for any given phosphatase, we have one gene that comes from the father and the other gene that comes from the mother. So let's suppose we have this homologous pair of chromosomes and this is the gene that let's say comes from the mother. And this is the gene showed in blue that comes from the father. So we have the pair of alleles that code for that same type of. So this should be phosphatase, not phosphatase. Okay?
