INHERITANCE OF ALBINISM IN THE GRASS CARP, CTENOPHARYNGODON-IDELLA

The inheritance of albinism in grass carp was investigated in a series of spawns involving wild-type colored x wild-type colored, albino x a lbino, wild-type colored x albino in both reciprocal combinations and the back-cross albino X (wild-type colored x albino). The results of t hese spawns showed that, as in rainbow trout, albinism is due to a sin gle recessive allele at an autosomal locus. Total length of albino seg regants was significantly less than that of wild-type segregants when grown together in a cage.
