Q1. An aquatic arthropod known as a Cyclops has antennae that are either smooth or barbed. The allele for barbs is dominant. In the similar organism, resistance to pesticides is a recessive trait. Make a “key” to show all the probable genotypes (and phenotypes) of this organism.

Q2. Acute renal failure. Ms. Jones, 68-year-old female, underwent open-heart surgery to replace some blocked vessels in her heart. On her first day postoperatively, it was noted that she had very little urine output.

What is happen to Ms. Jones’s kidneys, and why is it causing the observed symptom?
