n mice, dwarfism is caused by an X-linked recessive allele, and pink coat is caused by an autosomal dominant allele (coats are normally brownish). If a dwarf female from a pure line is crossed with a pink male from a pure line, in the F2 generation, what will be the probability of getting a dwarf and pink female?

    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).
