Orange the unaffected gene Blue the affected gene Both parents must pass on an affected gene for a chance of getting albinism in this case. That’s what you call it recessive inheritance.
One parent (who does have albinism) and one parent (who is a carrier of the albinism). In this case they have 4 children. Two children have albinism and two children who are carrier of the albinism gene.
