Know Oxy-Hb has a bright red hue.
Without it, we humans become too blue.
A Lack of Hb gives anemia,
No PBGD? A.I. porphyria.
Hydrops fetalis equals HbBarts,
Down’s trisome two-one gives defective hearts.
TNR problems include Huntington’s.
X-linked dominant’s how Rett syndrome runs;
Sick dads with all sick daughters, no sick sons
means dads’ X-alleles are dominant ones.
