Ohno's law (Genetics 🧬)

Ohno's law was proposed by a Japanese-American biologist Susumu Ohno, saying that the gene content of the mammalian species has been conserved over species not only in the DNA content but also in the genes themselves. That is, nearly all mammalian species have conserved the X chromosome from their primordial X chromosome of a common ancestor.
