Notes | Many animals use the timing of day length to anticipate changes in their environments. Day length is closely linked to seasonal activities such as reproduction. This article describes a study of a specific gene, the clock gene, and looked at variations in length of the polyglutamine domain of the clock protein in the three-spined stickleback. Sticklebacks from widely varying latitudes (northern Alaska and southern Oregon) were examined to see if variations in length of the polyglutamine domain corresponded with different latitudes. The study found no significant variation in length, and photoperiodic responses were similar in the differing latitudes.. |
