In an autotetraploid organism, the gene controlling coat color is very near the centromere of the chromosome carrying it. The allele Y for the yellow coat is dominant to y for blue coat. A homozygous yellow autotetraploid strain is crossed with a homozygous blue autotetraploid strain. What types and proportions of gametes would the F1 be expected to produce if the Y locus were 40 or more map units from the centromere? Derive the expected F2 phenotypic ratio. Please explain coherently. Thank you!

In a series of two-point mapping crosses involving five genes located on chromosome II in Drosophila, the following recombinant (single-crossover) frequencies were observed: pr–adp 29% pr–vg 13 pr–c 21 pr–b 6 adp–b 35 adp–c 8 adp–vg 16 vg–b 19 vg–c 8 c–b 27 (a) Given that the adp gene is 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 pr: d–b 17% d–pr 23% Predict the results of two-point mapping between d and c, d and vg, and d and adp.

Consider two loci A and B that are 30 cM apart on chromosome 1 in the fruit fly. A paracentric inversion is found to span about half of the distance between these loci, but not include either A or B. What is the approximate recombination frequency expected for these loci in … flies that are heterozygous for this inversion? RF(A-B) for heterozygous flies is … flies that are homozygous for this inversion? RF(A-B) for homozygous flies is …
