Mitotic and meiotic chromosomes of Artemia (Branchiopoda) from populations of La Pampa Province, Argentina

Mostrar todas las versiones(3)

Three populations of Artemia from La Pampa Province, Argentina, were cytogenetically analyzed: Salinas Grandes de Hidalgo, Laguna Callaqueo, and Laguna Colorada Chica. Both mitotic and male meiotic chromosomes were studied. All 3 populations share the same diploid (2n = 44) and/or haploid chromosome...
