Sex chromosomes and autosome of genetic sexing strain and wild-type B. cucurbitae. (A) Drawing of the sex chromosomes and the autosome containing the wp gene for female and male T1 Melon B. cucurbitae. The location of the wp gene has been crudely mapped to the tip of one of the autosomes, and a translocation between the Y-chromosome and the autosome harbors a wild-type allele (wp⁺) in males and are heterozygous at the locus in contrast to females, who are homozygous for the wp mutation. (B) Drawing of the sex chromosomes and the autosome containing the gene for female and male wild-type B. cucurbitae; wild-type individuals lack the wp mutation. Figure adapted from Franz (2005).
