Sibling recognition

How about a little context?

It seems to be a term from biology. An animal can tell when another animal has the same parents.

Elnur Hi. Could anyone explain the meaning of the above-mentioned expression?Thank you for your time.

It means that brothers and sisters recognize each other as having the same parent(s).

enoonHow about a little context?

Thanks

The example sentence on the usage of the word sibling was this : "And he recently completed a study specific to sibling recognition. It does seem simple, but i thought "sibling recognition" was a fixed expression.

There is also something like " sibling in prison ". Does it have a literal

The literal meaning is sibling in prison. I don't know what you are asking. If you are wondering whether there is such an expression, there is not.

Yes. I was asking that.
Thank you

It seems to be a topic in genetic research; so in that particular field of study, it might be a well-defined concept.
