Quantification of the expression of a temperature-sensitive pigment allele in sailfin mollies (Poecilia latipinna) by image analysis.

Abstract excerpt

Image analysis was used to quantify the activity of a temperature-sensitive macromelanophore-determining allele in sailfin mollies as the percentage of the body surface area covered by macromelanophores. Fish heterozygous for the macromelanophore-determining allele produced very few macromelanophores when raised at either 25 or 28 degrees C, even after more than 200 days. In contrast, the mean percent coverage...
