HI!
The answer would be A. Four long, zero short.
Here's why:
When looking at Punnett squares, you want to see if they are one thing or the other.
In this case, we are looking to see if the needles are long or short.
To figure this out, we can look in the boxes.
The top row has long needles because both of the letters are capitalized.
The second row is sort of confusing.
Both boxes have one capital letter and one lowercase letter.
When this happens, for this case, they are both long.
I hope this helps!
Feel free to mark brainliest!
