Question

If the characteristic is eye color, what could be two different phenotypes?

Can someone explain this to me please.

Answer 1

The phenotype is just a characteristic/trait.

For instance Brown and Green are phenotypes of eye color.

This can also be used in Punnet Squares, and could be displayed as B and G.
B equaling dominant Brown, and G = dominant Green, vice versa to g and b where they are recessive.
