Jurassic World Evolution 3 Guide | How To Increase Homalocephale Genome

A quick, repeatable method to raise Homalocephale genome progress for the Immunity quest.

Game Guide by Jubair Baky on Feb 16, 2026

If you need to increase the genome of Homalocephale for a quest step like Immunity, you can do it by researching the right dig site, running expeditions, and extracting fossils until you hit the required percentage. This process is simple, and you mostly repeat the same loop until you reach 70%.

Find Homalocephale In Dig Sites

Start by going to Research first. From there, open Dig Sites and look through the list until you find Homalocephale. Once you locate it, begin the research and wait for it to finish.

Send An Expedition To Mongolia

After the research finishes, open your Expedition Map. The location you need is in Mongolia. Select Mongolia, then send your team there. The expedition takes a few minutes, and this is what pushes your genome progress forward.

Process Fossils In The Science Center

When the expedition is complete, go to your science center and view the fossils your team found. Sell the fossils you do not need. Then focus on the fossils connected to the dinosaur you are building, especially the ones that help increase Homalocephale DNA. Start the extraction task and wait for it to complete.

Repeat Expeditions To Reach 70%

After extraction, check the percentage of your genome. One run may only raise it to around the low-to-mid 40% range, such as 43% or 44%, so you will likely need another expedition. Go back to the Control Room, return to the Expedition Map, and send the team back to Mongolia. As long as you repeat the same steps—expedition, fossils, extraction—you will keep increasing the genome until you reach 70%.
