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.

albinism is caused by a recessive autosomal allele. a man and a woman both normal, have an albino child 2. the mother is now pregnant for a 3 time, and her doctor tells her she is carrrying fraternal twins.allness (T) is dominant to dwarfiness (t), while red (R) flower color is dominant to white (r). the heterozygous condition results in a pink (Rr) flower color. a dwarf, homozygous red snapdragon s crossed with a plant homozygous for tallness and white flowers.
