In a nutshell grass requires potassium and nitrogen to grow and therefore sucks it up into the plant at every opportunity. This is facilitated by rainfall as it travels up into the plant with water. It is no coincidence that people report that their horses are âworseâ after rain.n a nutshell grass requires potassium and nitrogen to grow and therefore sucks it up into the plant at every opportunity.

Albinism results from inheritance of recessive gene alleles and is known to affect all vertebrates, including humans.culocutaneous albinism is generally the result of the biological inheritance of genetically recessive alleles (genes) passed from both parents of an individual for example OCA1 and OCA2.
Albinism is a genetic condition where people are born without the usual pigment (color) in their bodies. Their bodies aren't able to make a normal amount of melanin, the chemical that is responsible for eye, skin, and hair color. So most people with albinism have very pale skin, hair, and eyes. Albinism can affect people of all races, and there are different kinds of albinism. Some people with a condition called oculocutaneous albinism have extremely pale skin and eyes, and white hair. Others with this same type of albinism might have slightly more color in their hair, eyes, or skin. For some people, albinism affects only their eyes. This is known as ocular albinism. People with ocular albinism usually have blue eyes. In some cases, the iris (the colored part of the eye) has very little color so a person's eyes might look pink or reddish.
