Answer

**(a) Albinism is usually inherited in an autosomal recessive pattern.** **(b) Explanation:** Albinism is most often passed down when both parents carry a mutated gene. Each parent has one normal gene and one mutated gene. When both parents pass the mutated gene to their child, the child has albinism. This means the child needs to inherit two copies of the mutated gene—one from each parent—to have the condition. If only one parent has the mutated gene, the child will be a carrier but not have albinism.

Albinism typically follows an autosomal recessive inheritance pattern. This means that an individual must inherit two copies of the mutated gene (one from each parent) to express the condition. If a person has one normal and one mutated gene, they become a carrier but do not show signs of albinism themselves. In the case of albinism, the genes involved (most commonly the TYR gene) are responsible for producing melanin, the pigment that colors the skin, hair, and eyes. If both parents are carriers, there's a 25% chance that their child will inherit the condition, a 50% chance they'll be a carrier like their parents, and a 25% chance they'll inherit both normal genes.
