There is currently no conditional logic in Airtable’s Automations, unless you create your own custom JavaScript to create the conditional logic for you.
However, instead of using conditional logic, what you could do is have all your form submissions go into a temporary table, and then create TWO different automations: one automation that triggers if the field value is male, and one automation that triggers if the field value is female. Each automation can create one new record in its proper table.
Alternatively, for a no-code/low-code way of creating conditional automations, you can turn to Integromat, which has full support for both Airtable and Google Forms, and is free for up to 1,000 operations per month:
