Panthers are also susceptible to a respiratory infection [feline calicivirus].  Individuals in a population, who are homozygous dominant or heterozygous for genes encoding parasite or pathogen resistance, are more likely to resist an infection or parasite.  Currently, population estimates of the Florida panther range from 100 – 160 individuals.  Let’s assume that the population equals 160.  During a particularly bad calicivirus outbreak,   40 Florida panthers die as a result of the infection.  Using this information, answer the following questions utilizing the Hardy – Weinberg equation when necessary.     What is the most likely genotype of the affected panthers that died from the respiratory infection? Use the letter “A” for your symbol.         2. What percentage of the population is most likely resistant to the calicivirus infection?

Viral Infections

Viruses are abundantly found, minute entities that have genetic material enclosed within a protein coat. The proteinaceous material enclosing the genetic material of the virus is called a capsid. The genetic material could be either DNA (deoxyribonucleic acid) or RNA (ribonucleic acid). A virus is too minute to be looked at with naked eyes and therefore visualized with the help of a microscope. They are acellular entities that require a host for processes, such as replication, transcription, translation and multiplication. Plants, animals, and bacteria act as host wherein the virus reproduce. Viruses cannot multiply outside the host's body and thus are considered nonliving outside the host body.
