Trisomy 18 is one of the most common trisomies observed in human populations. You prepare DNA samples from two unrelated infants, both with trisomy 18, and from their parents. You then type the infants and their parents for four SSRs distributed along chromosome 18:
In which parent did nondisjunction occur in Family 2?

#Unit 12. Applied Biology
A successful biosensor must have some of the following features such as.
1. Should be highly specific for the analyte
2. Reaction used should be independent of factors like stirring, pH, temperature, etc.
3. Response should be linear over a useful range of analyte concentrations
