Answer:

Genotype can be described as the genetic makeup of an organism. Phenotype can be described as the physical characteristics which are observed in an individual.

For example, lets consider a male parent to be homozygous for brown eye colour which is  dominant, BB. The female parent has blue eye colour and is recessive, bb.

Let's make a punnet square,

         b         b

B    Bb        Bb

B    Bb       Bb

The results from the punnet square tell that all of the offsprings will have heterozygous genotype Bb, and the phenotype will be brown eyes.
