DNA replication
DNA replication is the process by which DNA makes a copy of itself during cell division. The first step in DNA replication is to 'unzip' the double helix structure of the DNA? molecule. ... The two separated strands will act as templates for making the new strands of DNA

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.
