Match the diseases to the pathogens that cause them. Diseases Pathogens P) Avian malaria i) Virus Q) COVID-19 in humans ii) Plasmodium R) Chytrid disease in frogs iii) Mosquito iv) Fungus
Show Hint
When testing biogeographic hypotheses, look for trees where the geographic distribution of clades matches the predicted colonization pathway.

Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Identify the causal agents (pathogens).
Avian malaria is caused by \textit{Plasmodium} species (e.g., \textit{P. relictum}); mosquitoes are \emph{vectors}, not pathogens \(\Rightarrow\) ii.
COVID-19 is caused by the coronavirus SARS-CoV-2 \(\Rightarrow\) a virus \(\Rightarrow\) i.
Chytrid disease in frogs is caused by the chytrid fungus \textit{Batrachochytrium dendrobatidis} (Bd) \(\Rightarrow\) iv.
Step 2: Assemble the mapping.
P–ii,\quad Q–i,\quad R–iv \(\Rightarrow\) option (C). Final Answer:
\[ \boxed{\text{(C) P–ii;\; Q–i;\; R–iv}} \]

- The molecular clock model assumes that mutation rates are:
- A few years ago, a very small population of zebrafish became isolated by a newly built dam. As a result, which statement is most likely to be true about this population of zebrafish now?
- In a population, there are two morphs, A and B, which reproduce at equal rates. A mutates to B with probability \(p_1\), and B mutates to A with probability \(p_2\) such that \(p_1 \gg p_2\) (that is, \(p_1\) is much greater than \(p_2\)). Over time, which one of the following statements would be true about this population?
- Consider a randomly breeding population of squirrels with two morphs – white-striped and brown-striped. In a population, 16\% are white-striped individuals, while the rest are all brown-striped. The trait for stripes is governed by one gene where the allele for brown stripes is dominant. Assuming Hardy–Weinberg equilibrium, the frequency of the allele for white stripes would be \_\_\_\_\_\_\_\_\_\_\_. (Round off to two decimal places)
- Which two of the following processes can result in a decline in heterozygosity in populations? I) Inbreeding; II) Genetic drift; III) Mutation; IV) Random mating

- In a locality, the houses are numbered in the following way:The house-numbers on one side of a road are consecutive odd integers starting from \(301\), while the house-numbers on the other side of the road are consecutive even numbers starting from \(302\). The total number of houses is the same on both sides of the road. If the difference of the sum of the house-numbers between the two sides of the road is \(27\), then the number of houses on each side of the road is:
