Bird Beak Traits



Scientists collected data about one bird population for five generations. The scientists determined the percentages of birds in the population that had specific beak shape traits, 1-6. The data are represented by the graph shown below.



The line graph titled 'Percentages of Beak Shape Traits in a Population' shows Generation from 0 to 5, in increments of 1, on the horizontal axis. The percentage of population with trait is shown on the vertical axis from 0 to 70, in increments of 10. A solid line labeled 'Beak shape Trait 1' starts at about 15%, gradually falls to 10% in generation 1, slightly rises then falls to below 10% in generation 3, then remains steady through generation 5. A solid line labeled 'Beak Shape Trait 2' starts at about 15%, gradually falls to 10% in generation 2, remains steady at 10% in generation 3, and falls to 0% in Generation 5. A solid line labeled 'Beak Shape Trait 3' starts just below 20%, falls to 10% in Generation 2, rises sharply to about 15% in Generation 3, then falls to slightly above 0% in Generation 5. The dashed line labeled 'Beak Shape Trait 4' starts at 20%, falls to below 10% in Generation 3, and continues to gradually fall to about 5% in Generation 5. Two dashed lines labeled 'Beak Shape Trait 5' and 'Beak Shape Trait 6' start slightly above 20%, rise to above 30% in Generation 1, then gradually rise to about 40% in Generation 3. At generation 3, the beak shape traits diverge. Beak shape trait 5 remains steady at about 40% in Generation 4, then falls to about 35% in Generation 5. Beak Shape Trait 6 sharply rises to 70% in Generation 5.



Which TWO statements about beak shape between Generation 3 and Generation 5 are supported by the data?


The percentage of birds with Beak Shape Trait 1 remained below 5%.


The percentage of birds with Beak Shape Trait 2 decreased from 10% to 0%.


The percentage of birds with Beak Shape Trait 4 showed a small increase to 10%.


The percentage of birds with Beak Shape Trait 5 steadily increased from 22% to 35%.


The percentage of birds with Beak Shape Trait 6 increased from 40% to 70%.

Correct statements:

- The percentage of birds with Beak Shape Trait 2 decreased from 10% to 0%.
(Trait 2 is about 10% at Generation 3 and falls to 0% by Generation 5.)

- The percentage of birds with Beak Shape Trait 6 increased from 40% to 70%.
(Trait 6 is about 40% at Generation 3 and rises to about 70% by Generation 5.)
