the curliness of a woman's hair (e.g. wavy) is her  phenotype while the allele combination (e.g. Cc) is her Genotype.

Explanation:

The phenotype refers to the visible characters, they are the expression of the genotype. In this case for example wavy hair.

The genotype on the other hand can not be seen because it is the set of alleles that in this case is represented by the letters Cc

for example, no new evidence will demonstrate that the earth does not orbit around the sun (heliocentric theory), or that living things are not made of cells (cell theory), that matter is not composed of atoms, or that the surface of the earth is not divided into solid plates that have moved over geological timescales .
