What is the total memory storage of the human genome?

[Tzikin]

My answer is that the 3Gigabits of base 4 memory in the human genome is equivalent to 750MB of binary standardised to 8 bits/byte.

Once I have taken into account that there are two copies, evolutionary junk and repeated or copied areas, I am getting an estimate of around 30MB.

... or about 30000 genes.
Tough you should think of it as a base ePROM storing a recipe.
Then the whole body is available as complimentary storage and the execution space is the range of action for the body.

A machine can do a lot with much less if it's reactions to instructions are context-based, self-referencing, and self altering. It's a basic lesson in AI. Then the instruction set is a recipe - how many different recipes fit in the same number of characters in a recipe book?

What I am trying to say is that it is not a useful calculation.
