Figure 1From: The fester locus in Botryllus schlosseri experiences selectionCartoon of the fester genomic structure. Top panel: A/A homozygote, Middle Panel: A/B1/B2 heterozygote, Bottom Panel: B1/B2/B1/B2 heterozygote. The C haplotype is not included because its composition and location relative to the A and B haplotypes is unknown.Back to article page
