Can two albinos have a normal child?
For most types of OCA, both parents must carry an albinism gene to have a child with albinism. Parents may have normal pigmentation but still carry the gene. When both parents carry the gene, and neither parent has albinism, there is a 25% chance at each pregnancy that the baby will be born with albinism.
Can humans have Leucism?
Therefore, leucistic phenotypes can be associated with defects, which mainly impair sensory organs and nerves. In humans, a well-known example is the Waardenburg syndrome. Leucism-associated disorders were also described in mouse, rat, hamster, rabbit, mink, cat, dog, pig, sheep, llama, alpaca, cattle and horse.
What country has most albinos?

Why do albinos eyes shake?
Nystagmus (the back and forth movement of the eyes) as well as the lack of pigment in the iris and the retina are also contributing factors to our reduced vision, although to a lesser degree. The easiest way to understand how the lack of cones affects the vision of people with albinism is to turn on your television.

They are overly sensitive to the sun and their appearance often makes them look very distinct. While that can create psychological problems, the visual impairment caused by a lack of pigmentation in their eyes is often the most difficult obstacle.
Do albino people have red eyes?

Graduated from ENSAT (national agronomic school of Toulouse) in plant sciences in 2018, I pursued a CIFRE doctorate under contract with Sun’Agri and INRAE in Avignon between 2019 and 2022. My thesis aimed to study dynamic agrivoltaic systems, in my case in arboriculture. I love to write and share science related Stuff Here on my Website. I am currently continuing at Sun’Agri as an R&D engineer.
