Unmarried children over 21 in Green Card Lottery Application

[Agapanthus]

Hello Everyone,

I would like to ask about the green card lottery (Diversity Program) please. Both me & my sister are older than 21 years old, if my parents applied for Green Card lottery can they include both me & my sister in the application? or my sister and I should apply separately from our parents application?

I know married children can not be included but if children are unmarried and older than 21 can they be included or is there any way to be with the parents in such case?

Thanks a lot in advance.
