Answer:
The answer is 2 birds.
Step-by-step explanation:
I got to this conclusion by drawing a Punnett square.
The punnet square is below:
t t
T Tt Tt
t tt tt
Therefore, the answer is 2 birds, with a fifty per cent chance of having the same recessive and a 50 per cent chance of having different dominant.
Note:
It didn't allow me to use the technical science terms for the 'same' and 'different' as the system thought they were inappropriate words.
