Cockapoos come in a variety of sizes and can weigh anywhere from 6 to 30 pounds. The weight of a cockapoo depends on the size of its parents.
The four types of oculocutaneous albinism each result from mutations in a single gene: TYR, OCA2, TYRP1, or SLC45A2. Changes in the TYR gene cause type 1; mutations in the OCA2 gene are responsible for type 2; TYRP1 mutations cause type 3; and changes in the SLC45A2 gene result in type 4.he four types of oculocutaneous albinism each result from mutations in a single gene: TYR, OCA2, TYRP1, or SLC45A2.

We normally have two copies of these chromosomes and genes: one inherited from our father, the other inherited from our mother. Albinism is a recessive trait - a person without albinism can carry the albinism trait. Both parents must carry a defective gene to have a child with albinism. When neither parent has albinism but both carry the defective gene, there is a one in four chance that the baby will be born with albinism.
