Genotype Alphas tend to have higher occurances of psychic abilities. The immune system of Genotype Alphas is extremely strong. They are most often found in outlying areas beyond Metris and Piscion. There is debate over wether Alpha Prime is a viable genotype. Genotype Alpha Prime members have less variable height, more tendancy to broad shoulders, and often curlier hair.
Noses tend to be larger.
Same traits as Genotype Alphas. Genotype Beta is a genotype that apparently evolved from a wave of immigration West of the major inhabited areas of Xai. There is some evidence that at least one of the Earths the Beta Genotype ancestors came from had genetic engineering or odd, unexpected mutations. Genotype Betas tend to put on weight less than other Genotypes. There are occasional outbreaks of autoimmune disorders unseen in Genotype Alpha or Gamma.
