Answer:
<em>If the Tamiflu-resistance gene involves a cost, it will experience directional selection leading to reduction in its frequency.</em>
Explanation:
The new virus will be resistant to Tamiflu. The Tamiflu resistance gene will become common in the environment due to directional selection. Directional selection can be described as a condition in which one phenotype is favoured such that the phenotype becomes abundant in an area and hence the allele frequency of the area changes. This occurs because that phenotype is better adapted to survive in an environment.
Answer:
Populations
Explanation:
Population refers to the total number of all members of a species occupying a particular area or habitat at a given time. Populations are not static but change in size. Some of the characteristics of population are:
- Density which refers to the number of members of species per unit area or volume.
- Distribution refers to the spread or dispersion of individuals of a species within an area or habitat. The movements are either emigration or immigration.
- Growth rate is the rate of increase or decrease in the number of individuals in a population and is determined by the balance between birth rate and death rate.
