Phenotypes
Explanation:
'Phenotype' is just a fancy way of saying 'what an organism looks like'. Those words describe an organism's physical appearance and not its genetic makeup--that's its genotype.

Phenotype
Physical characteristics/appearance
----
Genotype
Genetic makeup
They are variables that cannot be changed or are purposefully not changed in an experiment.
The muscle system for a boy and a girl are the same. They can perform and respond in the same manner. The difference only occurs in the development of muscle mass, where men can develop more muscle mass than female. This difference is brought by the type of activities that the two sexes engage in. Muscle group development can be altered by a person’s current exercise program and way of life.
