Question

There are two bears that both have the same proteins for ear shape in their cells. The bears have different parents. What can you say about the bears' ear shape?
Responses

a
They will have the same ear shape since their proteins for ear shape are the same so the proteins will connect in the same way.
They will have the same ear shape since their proteins for ear shape are the same so the proteins will connect in the same way.

b
They will have the same ear shape since all bears have the same ear shape.
They will have the same ear shape since all bears have the same ear shape.

c
They will have different ear shapes because even with the same proteins for ear shape, the proteins can connect in different ways.
They will have different ear shapes because even with the same proteins for ear shape, the proteins can connect in different ways.

d
They will have different ear shapes since only offspring from the same parents have the same ear shape.

Answer 1

a

They should have the same ear shape — if the proteins that build ear shape are the same, they will produce the same structure. (Note: in real organisms, gene expression and environment can also affect the final shape, but identical structural proteins predict the same basic ear morphology.)
