Question

A nectar-eating bird has a slightly more curved beak than average for its species. This allows the bird to more easily access nectar from plants. During the bird’s lifetime, it loses a toe on its left foot due to an accident. IT learns to compensate for this loss and is not greatly impacted. Which of this bird’s traits could it potentially spread through the species’ future population? Question 1 options: a. The slightly more curved beak because it is an acquired trait that would be beneficial to future offspring. b. The lack of a toe on the left foot because it is an acquired trait that would be beneficial to future offspring. c.The slightly more curved beak because it is a beneficial trait that is encoded in the bird’s genes. d. The lack of a toe on the left foot because it is a beneficial trait that is encoded into the bird’s genes.

Answer 1

C. 

Every change in a species is coded within the DNA. But the bird had lost a toe an accident. So the toe-loosing-option isn't true because not every bird looses his toe.

(Example: If a women gets bitten by a snake on the arm and gets the arm removed from her body and then in a year or so has a baby with her new husband. The baby won't be born with one arm because his/her mother lost her arm.) <span />
