Question
In the early part of the 20th century, a mathematician named Godfrey Hardy and a physician named Wilhelm Weinberg tried to use mathematics and statistics to describe how populations change over time. They found that because there are so many different natural forces that can affect the genetics of a population, the only way ther formula could accurately describe the population was if the genetics were perfectly stable and unchanging. This theoretical state is called Hardy-Weinberg equilibrium. In order for a population to reach Hardy-Weinberg equilibrium, five different assumptions need to be met The following scenario describes a population that is not at Hardy-Weinberg equilibrium because it specifically violates one of the five assumptions. Read the scenario and answer the questions that follow. For years, scientists in charge of studying urban pests thought that rats lived in family groups that did not venture far from their home territory. Public health workers would fight rat infestations by poisoning rats within a single building. Recently, though, it was discovered that there are some special types of rats that have no home territory and wander very far. These wandering rats breed periodically with territorial rats. Because of this, if one population of rats in one part of the city develops a resistance to the poison being used, the wandering rats can spread the allele to populations throughout the city One of the Hardy-Weinberg assumptions is that the population is large-in its strictest sense, that the population is infinitely large. The preceding scenario obviously violates this assumption in its strictest sense, because no real population is infinitely large. Which of the other four Hardy-Weinberg assumptions does this scenario violate? O Mating is random. O Mutations do not occur O The population is genetically isolated from all other populations of the same species All individuals survive and produce the same number of offspring. All of the Hardy-Weinberg assumptions rule out ways that the gene pools of populations can change. Thus, you can say that any population that does not meet all of the Hardy-Weinberg evolving. in the process of is notExplanation / Answer
1) Answer : Mutations do not occur & The polulation is genetically isolated from all other populations of the same species.
Mutations do occur thats why resistance is developed by rats.
And the population is not isolated as the rats move to other regions and share the resistance developed by it to other members of the population.
Hardy-Weinberg assumptions:
2) Answer : is in the process of evolving
Evolution depends on the following process to result in genetic diversity or biodiversity,
