Yes. There is a genetic link to IQ.

IQ doesn't test all kinds of intelligence though.

Iirc, you can alter your IQ, just as you can expand your other intelligence areas acumen.

In developing a specific intelligence acument (verbal, logic, interpersonal, nature, et al), you increase the odds that your offspring develop similar acumen

Iirc this finding is significantly leaning towards nurture, and not nature (,genetic)

Anyways cheers goodnight someone smarter than me please correct and source if you're diligent and stuff
