Question

The greater prairie chicken once flourished on the prairies of Illinois. The conversion of prairie to farmland reduced their numbers from millions to only 50 birds by 1993. Poor genetic diversity resulted in only 50 percent of eggs hatching. Bringing in birds from neighboring states increased their genetic diversity, which improved the egg-hatching rate to 90 percent. These changes in genetic diversity were the result of:

Answer 1

The changes in genetic diversity in the greater prairie chicken population were the result of introducing birds from neighboring states.

Step-by-step explanation:

The changes in genetic diversity in the greater prairie chicken population were the result of introducing birds from neighboring states.

The conversion of prairie to farmland reduced the numbers of greater prairie chickens, resulting in poor genetic diversity and a low egg-hatching rate.

However, bringing in birds from neighboring states increased genetic diversity and improved the egg-hatching rate.
