Abstract
Gynogenesis was used to map eight loci to their centromeres in Xenopus laevis. Several loci remote from their centromeres were identified. This information may be useful in distinguishing gynogenetic diploid progeny produced by suppression of second polar bodies from gynogenetic diploid progeny homozygous at all loci produced by suppression of first cleavage of gynogenetic haploids.
