Haemoglobin polymorphism inGadus morhua: Genotypic differences in haematocrit

Abstract

Haematocrit (erythrocyte/plasma ratio) values of the three commonHbI genotypes were recorded in two samples totalling 149 specimens of Atlantic cod (Gadus morhua L.) caught in the Trondheimsfjord, Norway, during March–April 1984. The haematocrit values were shown to depend on bothHbI genotype and sex; the females revealed higher average haematocrit values than males, and among the males theHbI-22 genotypes displayed higher average haematocrit values than the two other HbI genotypes.
