nope... if only it were that easy

"When dealing with Het x Normal and Het x Het breeding pairs, all the Normal-looking offspring have a chance of being Het, but you can’t tell by looking whether or not it has the gene. In a Het x Normal pairing…each offspring has a statistical 50% chance of carrying the gene, so it is called “50% Het”. In a Het x Het pairing, all normal babies have a 66% chance of carrying the recessive gene and that’s where the “66% Het” term comes from"

meaning all the babies have a CHANCE of carring the gene but not all will.
a pied to a normal will make 50% het pieds. not ALL of the babies will carry the gene.
