Harm of white turtle

White turtle is a special turtle disease, similar to human albinism, but not fatal.

The albino turtle is a kind of turtle. Its tyrosinase is negative and cannot form melanin, so its skin and shell are yellow and white, and neither iris nor choroid contains pigment, so its eyes are blood red.

The gene of albinism is located on the sex chromosome, so the traits it controls must be related to sex in heredity, which is called sex-linked inheritance. Moreover, the genes controlling albinism are recessive genes, which can only be reflected by homozygosity.

Human albinism:
