One of the X chromosomes in a particular Drosophila female had a normal order of genes but carried recessive alleles of the genes for yellow body color (y), vermilion eye color (v), and forked bristles (f), as well as the dominant X-linked Bar eye mutation (B). Her other X chromosome carried the wild-type alleles of all four genes, but the region including y, v, and f (but not B) was inverted with respect to the normal order of genes. This female was crossed to a wild-type male as diagrammed here.     1. Draw the meiotic prophase I chromosomes with maximal pairing from the inversion heterozygous female. 2. (continued) When a crossover occurs between v and f, please draw the resulting chromosomes in four gametes.
