Copper toxicosis is an autosomal recessive genetic disorder affecting certain dog breeds, causing chronic liver disease due to copper accumulation. In a breeding population of Bedlington Terriers, 32%32\%32% of the dogs are identified as heterozygous carriers for the disease-causing allele.
The wild-type dominant allele is known to be more common in this population than the recessive disease-causing allele.
Use the Hardy-Weinberg principle to calculate the percentage of dogs in this population that are expected to be affected by copper toxicosis. Show your working.
