Accessory chromosomes in gymnospermous plants (exemplified by Picea obovata Lib.)


, : Accessory chromosomes in gymnospermous plants (exemplified by Picea obovata Lib.). Dokl AN SSSR 196(5): 1213-1216

Two populations in Central Siberia showed the following chromosome numbers and frequencies of accessory chromosomes: 2n = 24, 72%; 2n = 24 + 1, 23%; 2n = 24 + 2, 3%; and 2n = 24 + 3, 2%;. The relative lengths and morphology of the chromosomes of the basic caryotype remained constant.

Previous work shows that folding a posthatching chick into the hatching position results in the re-initiation of hatching. Furthermore, bending the neck to the right or left serves as a selective signal for turning on hatching behavior. The presen...
