Stripes on an F1
This is an interesting photo. This is an F1 from one of my projects. You would not expect to see a gs phenotype in a F1 with only one parent carrying the gs gene. This is not uncommon in gs F1 crosses, but I don't recall one looking quite like this before.

Differences in the genetic background can influence the dominance or recessiveness of traits... so it can be modified under selection. However, it would be tricky to isolate what other genes are influencing the gs trait.

This is not too unusual. I find that many gs/+ heterozygotes have some faint striping - with some more than others. This allele is not completely recessive, and as noted above the heterozygous phenotype seems to vary some based on genetic background.
