A 21 and a 21 make a 21 - usually. The range is always in play; they might be a 20 or a 22, or some freak random head. I don't believe the genetics have anything to do with male or female.

thanks just wanted to know if the whole range still applied in at case. then after i posted i relooked at the 1st post and saw the chart were the same heads didn't get the same head kids.

Not sure if you are still tracking this, but I had an exception. I put a couple people on parenting last night and when I got up this morning I had this girl running around. By my calculations these two should've had a 15 16 17 18 or 19 but got a 29. Other than this kid my villagers have been spot on every time.

I have tryed the chart . It does work . I found an anomoly in the math . Here's an example . I got this 14+11 = 25 , 2/25 = 12.2 . If you get a .2 as in 12.2 your your child would be an 13 not 12 . anything over .1 to .9 , just move up one on the chart .
If this has been posted before I'm sorry, I didn't check every post .

Not an anomaly per se, I think, it's just that the machine rounds up, instead of rounding to the nearest.

Did you get that result through repeated trials, or only one pairing? The original poster claims that the decimal-children would be likely to, in this case, be a 12 OR a 13, without a greater likelihood of being one or the other. (With drift into the 10, 11, 14, 15 range)

you are right:i should avoid ugly kids now!

strange, but she is a nice kid!

This thread is great! Okay, I have maybe a dumb question though. Is it possible to rearrange the order of heads in the program, thereby rearranging the number system? But that, I mean the numerical order of the heads stays the same, but rearrange the heads, so that what was number 6, is now 26. See what I mean?

It may not be possible or completely irrelevant, not sure. I'm many things, but a programmer is NOT one of them

lol boy 28 is a mohawk

You don't have to be a programmer, pumpkin, but you would have to be good at modifying the game's image files. You could, indeed, rearrange the heads in the image files, but you would have to carefully align everything to make sure that the heads fit on the bodies properly after you've rearranged them.
