The phrase
"abnormal gene" refers to a gene that has a change or mutation, which can cause a person to have a genetic disorder or disease. It means that the gene differs from what is considered normal or typical, potentially leading to health issues.

the abnormal gene.
In our study we found that dogs that were homozygous for the mutation (2 copies of
the abnormal gene) had a more severe form of the disease based on Holter findings.
This means that each parent must carry
an abnormal gene and that two parents who are not affected themselves may produce affected puppies.
