Conclusions It should be emphasized that there are no similar educational materials in the national abnormalities in sex chromosomes in Chesterfield international market and that the next steps in this work refer to the production of an educational kit in partnership with a Brazilian company and subsequent referral of the INPI National Institute of Industrial Property letter to obtaining a patent.

Epub May Although the association of B chromosomes and sex in cichlids is still enigmatic, we could hypothesize that the B chromosome bias for females could favor their drive during female meiosis. Nonetheless, a minority of sSMC show similarities to B-chromosomes.

Here we report a survey on the current state of art of B chromosome investigation in cichlid fishes.

Since the full complement of DNA material is still present, balanced chromosomal rearrangements may go undetected because they may not result in disease. These studies started with discovery of B chromosomes in the abnormalities in sex chromosomes in Chesterfield Partamona helleri and moved on to the evidences of B chromosomes in other species of the genus.

We also have shown that B chromosomes undergo elimination independently of the root type. Previous analyses led us to suggest that the presence of B is a population-specific variation, but a comprehensive revision as well as increasing of sample is need to better understand these variations.

B chromosome science has advanced from classical conducted during most of the 20th century and molecular cytogenetics conducted from to genomics and bioinformatics approaches conducted during the last few years.

A study performed by The American College of Medical Genetics in correctly identified the gender in of cases. We then validated the results obtained by qPCR and tested the presence of the confirmed genes in A.
