Marble
Blushing
Multiple Locus Phenotype
Non-wild
alleles that interact to form this phenotype:
Marble (M), Stripeless
(S)

A marble
blushing angelfish is a marble with the addition of two Stripeless alleles
(S/S). Since marble can be homozygous (M/M) or heterozygous with one gold
marble or one gold allele (M/Gm or M/g), possible genotypes for a marble
blushing are:
M/M – S/S
M/Gm – S/S
M/g – S/S
A marble
blushing angelfish will have the distinctive pink circular area over the
gills when young. As an adult, the pink may no longer be visible, but the
marble blushing phenotype can be distinguished from non-blushing marbles
by the absence of any horizontal striations in the dorsal fin or any lacey
patterning in the tail.
