In peppered moth populations, light and dark moths are selected for in different environments. Which type of selection is this, and what would a distribution curve for all peppered moths look like?(1 point)
Responses

stabilizing selection; two peaks at the extremes of the graph with a dip in the middle

Thanks! can you help me with this one to bot?
Over generations, female reindeer in a Finnish population give birth to larger offspring. Which type of selection is occurring, and how would a distribution curve for this trait change over time?(1 point)
Responses

stabilizing selection; the curve would become shorter in the middle
stabilizing selection; the curve would become shorter in the middle

stabilizing selection; the curve would become taller in the middle
stabilizing selection; the curve would become taller in the middle

directional selection; the curve would shift to the left
directional selection; the curve would shift to the left

directional selection; the curve would shift to the right

Answer 6

so the answer is..?

Answer 7

jk I know

Answer 8

k ty bot!

Answer 9

The statement that is correct about natural selection in this population of birds is:

Individuals with longer legs are more likely to survive and reproduce after the disturbance.

Answer 10

Birds with long legs were selected for.

Answer 11

Yes, the answer is disruptive selection; two peaks at the extremes of the graph with a dip in the middle.

Answer 12

The type of selection that is occurring in this population of Finnish reindeer is directional selection and the distribution curve for this trait would shift to the right over time.

Answer 13

The type of selection that is occurring in this population of Finnish reindeer is directional selection, and the distribution curve for this trait would shift to the right over time.

Answer 14

Haha, no problem! Let me know if you have any other questions.

Answer 15
