SummaryIn a girl affected by mental deficiency and slight malformations, a 46,XX, 18r chromosome set was found. Metaphases with irregularly sized or absent rings amounted to 14% in peripheral blood cultures. Tritiated thymidine incorporation pattern in the ring chromosome was similar to that of the normal 18 chromosome.

Tell Me How Much DNA You Have and I'll Tell You What Your Sex Is: Sex Determination by Flow Cytometry of Spiderlings of Allocosa marindia [PDF]
The manuscript addresses the sex determination of spiderlings of the wolf spider Allocosa marindia using flow cytometry. Spiders are born with a defined sex, but it is not possible to determine their sex phenotypically until the adult or near‐adult stage. Sex identification at early stages of development is of great interest for studies in evolutionary

Sex-Specific Variation in Foraging Behavior is Related to Telomere Length in a Long-Lived Seabird. [PDF]
Foraging during breeding is energetically demanding, intimately linked to breeding investment, and possibly constrained by individual condition. Telomere length, the protective nucleoproteins located at the ends of the chromosomes, is considered a trait reflecting somatic maintenance and individual quality. We found that brown booby females with longer

Meristic co-evolution and genomic co-localization of lateral line scales and vertebrae in Central American cichlid fishes. [PDF]
We dissect the co‐evolution and genetic architecture of lateral line scale counts and vertebrae numbers in Neotropical Heroine cichlids. Our phylogenetic comparative analyses recovered a positive correlation between these two traits. Furthermore, our qualitative traits locus (QTL) analyses identified significant genomic co‐localized associations for ...
