よ and だよ

[ash341986]

Hello everyone, I have a question about the use of よ and だよ (as in 冗談よ and 冗談だよ) as I watched Detective Conan episode 944 and read Harry Potter in Japanese. What is the difference between the two?

Here are the contexts:
1. The timid new teacher in Conan's school shrieks when Haibara tells her there might be a skeleton in the basement, and then Haibara calmly says 冗談よ.

2. When George jokes about sending back home a Hogwarts toilet seat, Mrs. Weaseley snapped and he says 冗談だよ.

Thank you in advance!

冗談よ is spoken by a woman.
冗談だよ is spoken by a man.
In colloquial Japanese, feminine wording and masculine wording differ in many cases.

That makes sense! Thank you so much!
