Chromosomes of the experimental hybrid of Crussostrea virginica Gmelin 1791 and Crussostreu rhizophorue Guilding 1828 (Pseudolamellibranchiata: Ostreidae)

The cytogenetic study of the interspecific larval hybrid of Crassostrau virginica and Crassostrea rhizophorae has been conducted. The chromosome complements in all the types of hybrids assayed were integrated in a normal way to form the zygote and the chromosome number was consistently 20. Only biar...

Sumario:The cytogenetic study of the interspecific larval hybrid of Crassostrau virginica and Crassostrea rhizophorae has been conducted. The chromosome complements in all the types of hybrids assayed were integrated in a normal way to form the zygote and the chromosome number was consistently 20. Only biarmed, homomorphic isopignotic chromosomes were present. Chromosomes of the hybrid karyotype are similar to those of the progenitor species, especially to those of C. virginica
