Improved Genetics – At Least One of These Should Be Added

The genetics system in The Sims 4 is too predictable, and too repetitive especially in long legacy saves. There’s little variety over generations. At least one of the following improvements would make a big difference:

Dominant & Recessive Genes – Traits like eye and hair color could follow dominant/recessive logic, allowing rare traits to appear if both parents carry them. Like in Sims 2.

Grandparent Influence – Children could inherit traits that skip a generation, such as a grandparent’s hair, eye color, or facial features. 

Updated Hair Color Percentages – In the current system, some eye colors share the same probability. For example, green eyes and hazel eyes have the same chance of being passed down, so a hazel-eyed parent can have a green-eyed child. If this level of detail exists for eyes, the same logic should apply to hair. Hair shades that are close to each other — such as dark blonde ↔ light brown, dark copper ↔ light copper, or dark brown ↔ black — should be interchangeable in inheritance to create more natural and varied results.

Any one of these would make genetics more varied and keep legacy gameplay fresh and exciting. Please Sims Team consider adding at least one of these.
