what category of cancer-related genes is it possible to find inherited variants that are associated with cancer?  Why? Group of answer choices 1. Tumor suppressor genes, because genes in this category are very important in the process of developing cancer. 2. Proto-oncogenes, because individuals who carry only one cancer-causing allele will have a wildtype phenotype. 3. Proto-oncogenes, because there are very few genes in this category, so mutations in them are rare. 4. Tumor suppressor genes, because individuals who carry only one cancer-causing allele will have a wildtype phenotype.
