A. 9:3:3:1 ratio (9 polka-dot tails and long eyelashes, 3 polka-dot tails and short eyelashes, 3 solid tails and short eyelashes, 1 solid tail and short eyelash)
B. 9:3:3:1 ratio (9 polka-dot tails and short eyelashes, 3 polka-dot tails and short eyelashes, 3 solid tails and long eyelashes, 1 solid tail and long eyelash)

When two individuals heterozygous for both traits (tail color and eyelash length) having genotype (PpLl) are crossed, four types of individuals are produced. The probability of phenotype combinations of offspring is the ratio 9:3:3:1.

9 - polka-dot tails and long eyelashes

3 - polka-dot tails and short eyelashes

3 - solid tails and long eyelashes
