Question

Use the following information to answer the next question Five conditions are required to maintain the Hardy-Weinberg equilibrium in a population 1. Closed population 2. Large population 3. Random mating 4. No net mutations 5. No natural selection If any of these conditions is not being met the allele frequencies in the population will change, leading to microevolution in the population Match each of the followi scenarios to the Hardy-Weinberg condition that is NOT being met: An increase in antibiotic resistance among bacteria exposed to antibiotics occurs. Caribou from one herd move to a new area and breed with caribou of a completely different herd. Among eastern bluebirds, more brightly coloured males breed with more brightly coloured femates. Due to overhunting, there is little genetic diversity in the current population of bearded vultures, which have all descended from a population of only 36 birds.

Answer 1

1) An increase in antibiotic resistance among bacteria exposed to antibiotic occurs

In this case, the conditions no natural selection and no net mutations are not met. Antibiotic resistance occurs via natural selection. Those bacteria which have a mutation allowing them to survive will only live on. Both mutation and natural selection occur in this case.

2)Caribou from one herd move to a new area and breed with Caribou of a completely different herd

In this case, the condition closed population is not met. Caribou moves from its herd and breeds with member of another population. The term closed population refers to a population with no migratory flow in or out.

3) Among eastern blue birds, more brightly colored males breed with more brightly colored females.

In this case, the condition random mating is not met. Random mating refers to the situation when any male of the population breeds with any female of the population (irrespective of colour or any other features).

4) Due to overhunting, there is little genetic variation in the current population of bearded vultures,which have all descended from a population of only 36 birds.

In this case, the condition large population is not met.The population of the bearded vultures are descendants of just 36 birds. The population is now becoming small due to overhunting.
