Percentage of heterozygous offspring in the gynogenetic diploid crosses along three acrocentric chromosomes where the p arm has been identified: Ots19, Ots20, and Ots33. On the x-axis, the distances are oriented from the p arm. Three gynogenetic crosses were used (F978, F981, and F984). The centromere is located where the percentage of heterozygous offspring is about zero.
