biologyAssume that three pairs of alleles are found in Drosophila:
$$
x ^ { + } \text { and } x , y ^ { + } \text { and } y \text { , and } z ^ { + } \text {and z}
$$
As shown by the symbols, each non-wild-type allele is recessive to its wild-type allele. A cross between females heterozygous at these three loci and wild-type males yields progeny having the following genotypes:
$$
1010 x ^ { + } \cdot y ^ { + } \cdot z ^ { + } \text { females, } 430 x \cdot y ^ { + } \cdot z \text { males, } 441 x ^ { + } \cdot y \cdot z ^ { + } \text { males, } 39 x \cdot y \cdot z \text { males, } 32 x ^ { + } \cdot y ^ { + } \cdot z \text { males, } 30 x ^ { + } \cdot y ^ { + } \cdot z ^ { + } \text { males, } 27 x \cdot y \cdot z ^ { + } \text { males, } 1 x ^ { + } \cdot y \cdot z \text { male, and } 0 x \cdot y ^ { + } \cdot z ^ { + } \text { males. }
$$
a. On what chromosome of Drosophila are the genes carried? b. Draw the relevant chromosomes in the heterozygous female parent, showing the arrangement of the alleles. c. Calculate the map distances between the genes and the coefficient of coincidence. 15th EditionJohn David Jackson, Patricia Meglich, Robert Mathis, Sean Valentine249 solutions
