This is a di-hybrid cross example. You can use a large punnet square to work out all the possible phenotype combinations in the offspring, however the shortcut is the 9:3:3:1 ratio. The phenotype outcomes of this ratio can be inferred directly with dominant alleles filling the 9 ratio. The 3 ratios are one dominant and one recessive for each of the two genes, and finaly the 1 ratio is recessive allele for both genes.
Like so:
9 Polka dot tail and long eye lashes
3 Polka dot tail and short eyelashes
3 Solid tail and long eye lashes
1 Solid tail and short eye lashes
The answer is D.
