| Study: Single Genomic Region Strongly Influences Life History For Steelhead/Rainbow Trout Posted on Friday, January 09, 2015 (PST) |
| A region of a chromosome known as “Omy5” strongly influences whether a steelhead will head to the ocean to grow or remain in its home river or lake as a resident rainbow trout.
Geneticists studying steelhead and rainbow trout in California and southern Oregon — two forms of the species known as Oncorhynchus mykiss — identified the chromosomal region and published their results last year in the Proceedings of the Royal Society. |
