Got it.

I'd go for HD/+, since context is perfectly clear.

I should caution that my answer has no official standing. I do have a
background in genetics, mainly microbial. I’ve answered more on
"logic" than anything. Certainly the page you referred to does not
address this specifically.

Perhaps with your clearer (more focused) question someone will jump
in, if there is some official subtlety that you need.

Also note that journals can be very helpful here. Choose a relevant
journal, and check their instructions for authors (usually online
nowadays, and in some issues). The journals have a real stake in
making their rules clear, as it makes things much easier for them.
