Marcus found a company that is able to test for the HLA-DQA1 gene. The company needs a sample of the puppy’s chromosomes to run the test.
Below are four samples from Marcus’s puppy. All samples were treated with a stain that stains genes so these will show up darker. (Think about the specific cell part that we find genes before making your choice!)
To test for the HLA-DQA1 gene, which sample should Marcus send?
