Summary
In the Polychaete wormOphryotrocha diadema, the yellow coloration of egg yolk is due to the selective uptake of lutein from food. The genetic control of this mechanism depends on a single locus with 2 alleles, the dominantY (yellow) allele, and the recessivey (absence of coloration) allele.
