Answer:Recessive traits
Explanation: Albinism is a reccessive traits whose effect have been suppressed by the dominant traits in the parents phenotype.
Complete dominance occurs when an allele A completely dominate over allele a in the genotype of an organism.
For the parents to have given birth to a non albino it means they are heterozgous dominant(Aa) and a cross between two heterozygous dominant parents will result in one homozgous non albino,2 heterozygous non-albino and 1 homozygous albino with the phenotypic ratio of 1AA 2Aa,1aa
