FIRST LINKAGE OF A SPECIES ANTIGEN IN THE GENUS STREPTOPELIA.

Twenty-two progeny in a single backcross family of a species hybrid between the dwarf turtle dove and the ring-neck dove exhibited strong association in a repulsion phase of linkage between the silky feather trait and the species-specific hu-8 blood character. This family constituted a test cross for six characters: sex, peanut reactivity, silky feathering, and the three independent species-specific blood characters, hu-1, hu-4, and hu-8.
