Answer 1

1. piebald

Piebald spotting: This is a good example of incomplete dominance and variable expressivity.

2.

3. bb

this shows the recessive genotype

4. Eumelanin gene

Despite the huge variety in coat colour, there are only two basic pigments that determine the colour of canines: eumelanin (black) and phaeomelanin (red). All different variations in colour are created by these two pigments, which are both forms of melanin.
