> Melanin is synthesized from the amino acid tyrosine by the enzyme tyrosinase.
Actually, tyrosinase converts tyrosine into L-dopamine. That conversion is just the beginning of the process required to make melanin. Several more steps and other enzymes are needed to synthesize melanin from L-dopa.
As far as I know, nobody has actually tested brooksi albinos for tyrosinase. So these albinos may be T-positive albinos or may be T-negative albinos.
Here's how to tell the difference between a dominant mutant gene and a recessive mutant gene. Look at an animal with a gene pair made up of a normal gene and a mutant gene. If the animal looks normal, then the mutant gene is recessive to the normal gene. If the animal does not look normal, then the mutant gene is dominant to the normal gene.
