Black Pearlscale
Multiple Locus Phenotype

Non-wild alleles that interact to form this phenotype:

• Dark (D)

• Pearlscale (p)

 

A black pearlscale is a black angelfish with two doses of pearlscale.  It may be homozygous for dark (double dark black) or may be a hybrid black in which the dark alleles is paired with a recessive gold, gold marble, or marble allele.

Possible genotypes for black pearlscale include:

D/D – p/p
D/g – p/p
D/Gm – p/p
D/M – p/p 

Pearlscale is a recessive trait so the angelfish must be homozygous (double dose) for pearlscale.  With the pearlscale trait the scales are aligned and shaped to be more reflective of light than wild type scales.  Pearlscale doesn’t show up very well against dark coloration, so a black pearlscale will not appear as shiny as lighter colored varieties of pearlscale.
