Phenotype = outcome letter
The phenotype is the physical appearance, trait or characteristic the offspring ends up with. E.g. blue eyes, short fingers or a long nose.
The best way to think of phenotype is the outcome letter or the letter that wins to give an outcome.
Phenotype = Outcome letter
Feed no typewriter (phenotype) otherwise outcomes a letter.
It is important to remember that the phenotype is not the letter but the physical characteristic or trait that the letter represents, such as eye colour.
The physical outcome will be the result shown in the punnet square.
