  The dоctrine оf __________ requires cоurts to follow аuthoritаtive prior decisions when ruling.  

A genetic cоnditiоn is cаused by а recessive аllele. It develоps later in life, and is very harmful if untreated, but it can be prevented with appropriate treatment. A couple (A. and J.) with young children learn that they each have a parent who has the condition. Neither A. nor J. currently have symptoms of the condition, but they could have the recessive allele and develop the condition and/or pass it on to their children. The parents decide to get the whole family screened so they know whether any of them will need to get treatment to prevent the condition. The genetic counselor they work with gives them the following information: the dominant allele (N) results in two DNA fragments - one 90 bp and one 60 bp long the recessive allele (n) results in a DNA fragment that is 150 base pairs (bp) long each individual has 2 alleles for the gene, and can have the genotype NN, Nn, or nn The gel with the family's results is below. The DNA ruler in the right side contains DNA fragments that are 50, 100, 150, and 200 bp long. The DNA was loaded at the top of the gel as shown in the image & the DNA fragments moved toward the bottom. The band in the DNA ruler that is 50 bp long is band [a]. When running the gel, the DNA moved from the top to the bottom of the gel, so the positive charge would have been applied to [b].
