Genetics/map distance (urgent)

The figure at right shows two homologous pairs of chromosomes during the G1 phase of a female fruit fly Drosophila melanogaster; the maternal and paternal chromosomes are shown in red and light blue, respectively. This female is heterozygous FfGgHh at three loci; the G and H loci are located 8 cM apart on the larger of the two chromosomes, while the F locus is located on the smaller separate chromosome.

A. Write the genotypes of all possible haploid gametes this female could produce, and specify the frequency of each gamete type expressed as a percentage of all gametes (solved)

B. Now imagine a male fruit fly with the same genotype and same arrangement of alleles on the two chromosomes. Write the genotypes of all possible haploid gametes this male could produce, specify the frequency of each gamete type expressed as a percentage of all gametes, and briefly explain why your answer differs from your answer to part A above.
