SOLVED: The Drosophila miniature gene is located on the X chromosome. Flies that are recessive for the m allele are significantly smaller than wild-type flies. If you cross homozygous miniature females with homozygous normal males, what proportions of phenotypes and sexes should you expect in their offspring? 50% miniature females and 50% normal males, 25% miniature females and 75% normal males, and 50% miniature males and 50% normal females. All offspring will be of normal size, regardless of s

In a series of two-point map crosses involving five genes located on chromosome II in Drosophila, the following recombinant (sin- gle-crossover) frequencies were observed: p r-a d p 29 p r-v g 13 p r-c 21 p r-b 6 a d p-b 35 a d p-c 8 a d p-v g 16 v g-b 19 v g-c 8 c-b 27 (a) If the adp gene is present near the end of chromosome II (locus 83 ), construct a map of these genes. (b) In another set of experiments,

SOLVED:In a series of two-point map crosses involving five genes located on chromosome II in Drosophila, the following recombinant (single-crossover) frequencies were observed: (a) If the adp gene is present near the end of chromosome II (locus 83 ), construct a map of these genes. (b) In another set of experiments, a sixth gene (d) was tested against b and p r, and the results were d-b=17 % and d-p r=23 % Predict the results of two-point maps between d and c, d and v g, and d and a d p
