Answer:
The probability of getting a dwarf and pink female is 1/2
Explanation:
In mice, dwarfism is caused by an X-linked recessive allele, and pink coat is caused by an autosomal dominant allele where coats are normally brownish.
A dwarf female from a pure line will have Xd Xd where d represent the recessive trait and the female is also brownish (pp).
A pink male from a pure line will be XPY where P represent the dominant allele but not a dwarf (D).
