I just found your channel and I have had a very personal interest in genetics since I overheard a conversation when I was little 😅 I'd love to see the video on sex-linked traits and genetic disorders, but I couldn't find it. Do you have a link or the title of it?

[@InteractiveBiology]

Ah man - I never got around to making that one. It's on my list though, so stay tuned.

[@bangtan4342]

I need a vide regarding gene expression : lac operon and trp operon plzz

[@InteractiveBiology]

Yep, that's on my list of things to cover. Stay tuned.

Hi mad respect 🙏 🫡 from Pakistan ,Sir I'm requesting to you please do lectures on pathophysiology (bsn patho) because your lectures are very helpful for us ...please 😊 your method of conducting lecture is very effective 👌

[@InteractiveBiology]

Hi, I do have a few Pathophysiology videos on the channel but not many. I should do some more. Here are the ones that I have (on hypertension): pulse.ly/h2zpxtovs3 pulse.ly/g1ekuhpm3l pulse.ly/0izbvlmqtr
