This is the expected distribution of progeny for the mating above. The probability of a particular combination of phenotypes is obtained as the expected number of that combination divided by the total number. For this mating, find the probability of an albino with short hair and a dew claw.

C - designates a dominant allele for expression of color. The recessive c produces the albino phenotype when homozygous. L - designates a dominant allele for short hair. The recessive allele l produces long hair when homozygous dd. D - designates a dominant allele associated with no dew claw. The recessive d produces a single dew claw when homozygous.
