Can someone help me with this, also brainliest.
PUNNETT SQUARES

Explanation:

G- green feathers

g- yellow feathers

L- long beak

l- short beak

Letters are the easiest way of modeling a Punnett square. The big letters mean it's dominant, while the lower case means it's recessive. Dominant traits will show up over the recessive traits. The answer is 75% because if the female is heterozygous, her alleles would be Ll, and as I said before, the big letters take over the little letters in any case.

I hope this helps :)
