Why do genetics sometimes include green tea colored hair on The Sims 3?

[76561198213095365]

Just asking because yellowish green hair looks unnatural on The Sims 3. For example a natural blonde and a natural redhead giving birth to a child, but when the child is born hair looks like a mix of green and a hint of blonde (or in other words "yellow) that makes the hair look similar to green tea that does not really make the child look related to the parents. I also noticed as well if the parents have blue and grey eyes their is a chance that child might have green eyes even if none of the parents have green eyes or red hair even if the parents do not have red hair such as blonde and brown for example.

Recessive genes. That's how it works in real life, as well.

Real Life:
Two people with brown hair and brown eyes can, albeit rarely, get a blonde haired, blue eyed, child, if both parents had a blond and blue-eyed ancestor.

One brown eyed parent matched with a blue eyed parent can produce children with green or hazel eyes. Eye color is a little more complicated because it involves the amount of color saturation in the iris. Blue-eyed people lack melanin in their iris, so their eyes look blue to us. The more melanin, the darker type of color you will see. Green is the in-between color. Hazel is the next darker shade.

A brown-haired parent matched with a blond-haired parent can get a red-haired child. Think Prince Charles (now King) and princess Diana. Prince Harry has red hair. Red hair is more a causation of genetics, however. You need to have the right combination of two different types of melanin.

Brown is the dominant gene. Genes for red hair and blond hair and for light-colored eyes are recessive. This means that the more likely outcome for any pairing involving a person with brown hair or eyes will create another person with brown hair and eyes.

There are no recessive genes in Sims 3. That's not how the system works.

When a baby is born, it has a 20% chance of having a mutated hair color and a 10% chance of a mutated eye color, mutated in this case meaning not the color from anyone in the family. When the color is mutated, it is guaranteed to be one of the presets you see in CAS; the game will never choose a truly random color.

If the baby has grandparents that exist in the world, alive or dead, it has a 50% chance of receiving the hair color and a 50% chance of receiving the eye color of a grandparent. The effective chance appears lower because the grandparent's color in this case may match the parent's color, so it's not clear that the sim inherited directly from the grandparent.

These values can be changed with NRaas Retuner. I've done so in Dragon Valley, setting the mutation chance to zero for both and lowering the chance of inheriting from a grandparent to 20%, because I want the lovely odd colors to persist through the generations.

Even though inheriting from grandparents mimics dominant/recessive genetics in some ways, that's not actually an accurate description because the game doesn't assign any colors to be dominant relative to others. For example, two blond-haired sims with a black-haired parent can have a black-haired child just as easily as the other way around.

Well, I wasn't trying to equate human genetics with how the game works, but I did word things improperly in that regard. The game is just trying to simulate a little of what the actual human experience is, while also being a little more creative. Also, the OP seemed to not know that humans can have these odd outcomes, as well, so I was giving some explanation and examples to show that yes, humans can also have similar outcomes like what the game has. It IS natural for humans to give birth to children that don't look like them, in certain ways.

Thank you, puzzleaddict, for your detailed explanation of how the game actually works in this matter. Your are a fountain of Sims 3 knowledge and expertise that I am extremely grateful to have here on these discussions pages.

Is the natural tea hair color from The Sims 3 recessive as well? Nobody has answered my question about babies born with the tea hair color and in real life this hair color is unnatural to humans. People in real life do not have any shade of green as a natural hair color at least that I aware of even with different variations of blonde in real life such as platinum which is the lightest color of blonde, blonde (which is darker than platinum blonde but no brown and not aware of it having any green either), and dirty blonde (a mix of brown and blonde) for example. You brought up some good points, but made no mention as to why I had a grandchild born with yellowish green hair. I am certain that plenty of people have seen this strange hair color before on The Sims 3 where it makes sims have a hair color that resembles the Joker villain (especially Heath Ledger) from D.C Comics.

Again, there are no recessive genes in Sims 3. The color you're describing sounds like one of the default colors you see in CAS. The hair color for this particular child is the result of a random mutation, where the game first rolls the outcome that the child's hair color will be mutated and then picks one of the random default colors.

If you're not sure whether the child's hair color is one of the defaults, take them into CAS and see how their hair color is listed.

Thank you. I do believe that genetics (especially skin color, facial structure, and body type) do play an important role on The Sims 3 even if recessive genes have nothing to do with it, but maybe I could pretend the hair color was dyed and leave it alone just for the fun of it even it is one of the random default hair colors which actually seems to be quite common as well on The SIms 3, because I have seen plenty of sims with this hair color on The Sims 3. I plan on using one of my male sims towards having four sons total with his wife (which can definitely be accomplished especially with the use of mods) who will be my main character's (also named David Noble) grandchildren. So the chances are probably that not all of the children will have a green tea hair color or at least I am hoping for this, but if I am wrong I might change the hair color for some of them since I am not really a big fan of the default greenish hair color and overall prefer hair colors that look more natural to humans. The children are biracial who have a white father with red hair and black mother with possibly platinum blonde hair (which was the black woman's default hair color and one of the random townies in my game).

You did not mention anything about genetics which are not "random" (such as skin color, body type such as skinny vs. fat and body shape for example, and facial structure that is perhaps supposed to look similar to parents), but that is perhaps the closest answer to my question at least when it comes to explaining hair color and perhaps eye color as well. A child having green eyes despite neither parents having green eyes for example possibly could be random on The SIms 3 similar to hair color.

I just noticed another pleasant surprise. When I had myself cloned from an adult who was soon about to become an elder I surprisingly noticed that my child clone looked very similar with identical traits and identical eye color, but the hair color was green despite my older sim having brown hair. They did not match despite brown I was using being one of the default hair colors. I might however play along with the green hair just as a reminder that my sim was cloned despite the other similarities in appearance besides hair color. Despite him being a clone that does not necessarily mean that he will have the same clothes (including miscellaneous items), the same traits (especially the investigator trait since it is only really useful for investigator career), or even the same job when he eventually ages up to young adult. I have never played a childhood version of myself on The Sims 3 which was the reason why I made a clone.
