Chapter 4, Problem 32P

In rabbits, albinism is an autosomal recessive conditioncaused by the absence of the pigment melanin from skin and fur. Pigmentation is a dominant wild-type trait. Three purebreedingstrains of albino rabbits, identified as strains $\text{1, 2}$ and $\text{3}$, are crossed to one another. In the table below ${\text{F}}_1$ and ${\text{F}}_{\text{2}}$ progeny are shown for each cross. Based on the available data, propose a genetic explanation for the results. As part of your answer, create genotypes for each albino strain using clearly defined symbols of your own choosing. Use your symbols to diagram each cross, giving the ${\text{F}}_{\text{1}}$ and ${\text{F}}_{\text{2}}$ genotypes.
