Cytogenetic analysis of three catfish species of the family Pseudopimelodidae (Teleostei, Siluriformes)

The objective of this study was to examine the chromosomal location of 18S and 5S ribosomal DNAs, and the base composition of B chromosomes in a population of

O ponto de partida no desenvolvimento da ontologia consistiu na busca da informação necessária para dar resposta às inevitáveis questões sobre o domínio e

In this case, we find a derived state for the distribution of 18S ribosomal cistrons in synteny with regions 5S, the latter scattered in many others chromosomes in the

These are: Anus to anal-fin distance; Adipose-fin base length; Anal-fin base length; Anterior to posterior nostril distance; Body depth; Caudal peduncle depth; Caudal
