Question

There are two junco birds that each have different proteins in their cells for beak pointiness. They have different parents. What can you say about the birds' beak pointiness?
Responses

a
They will have the same beak pointiness because even with different proteins for beak pointiness, the proteins can connect in the same way.
They will have the same beak pointiness because even with different proteins for beak pointiness, the proteins can connect in the same way.

b
They will have different beak pointiness since offspring from different parents will have
different beak pointiness.
They will have different beak pointiness since offspring from different parents will have different beak pointiness.

c
They will have different beak pointiness since their proteins for beak pointiness are different so the proteins will connect in different ways.
They will have different beak pointiness since their proteins for beak pointiness are different so the proteins will connect in different ways.

d
They will have the same beak pointiness since all junco birds have the same beak pointiness.

Answer 1

c

Different proteins that affect beak pointiness will typically produce different structures/functions, so the birds will have different beak pointiness. (Having different parents alone doesn't guarantee different traits.)
