In Scenarios 2 and 3, the brown fur mutation is present and is a dominant gene. The number of brown rabbits and white rabbits at the end of these scenarios is very different. To explain this difference, label the following statements as TRUE or FALSE. (3 points) TRUE FALSE In Scenario 3, the rabbits are choosing to pass on the brown fur trait. In Scenario 2, there is no selective pressure. Rabbits that are able to hide from wolves are more likely to pass on their genes. In Scenario 3, the selective pressure from the wolves makes brown fur an advantageous trait The brown fur trait becomes the most common trait because it is a dominant gene.

1 answer

Here are the answers to the statements based on the provided scenarios:

  1. In Scenario 3, the rabbits are choosing to pass on the brown fur trait. - FALSE

    • Rabbits do not have the conscious ability to choose traits to pass on; this is determined by genetic inheritance and environmental factors.

  2. In Scenario 2, there is no selective pressure. - TRUE

    • A lack of selective pressure means that traits can propagate through a population without environmental challenges influencing survival and reproduction, assuming all other conditions are equal.

  3. Rabbits that are able to hide from wolves are more likely to pass on their genes. - TRUE

    • If hiding from wolves is advantageous for survival, then those rabbits with traits (like brown fur, in this case) that help them avoid predation are more likely to survive and reproduce.

  4. In Scenario 3, the selective pressure from the wolves makes brown fur an advantageous trait. - TRUE

    • If the brown fur provides better camouflage from wolves, it would be considered an advantageous trait under selective pressure.

  5. The brown fur trait becomes the most common trait because it is a dominant gene. - FALSE

    • While the brown fur being a dominant trait can contribute to its prevalence in the gene pool, the frequency of its occurrence also heavily depends on selective pressures and environmental factors, not just its dominance.
