Do the parents affect the nature of the off spring?

[AndrewPDes]

In any way shape or form? For example, if I breed two adamant machops, will the child have a higher chance of being adamant? If I max out Coolness on both parents, will the child be more likely to have a nature that boosts attack?

I don't think Pokéblocks have an effect on the nature of the baby, but I do believe that in some way, the parents' natures have an effect.

I don't know for sure, but one time when I was trying to breed up a Beauty-loving Castform for one of the contests, I always ended up with one of a certain set of personalities, and nothing more. I only got a proper nature (it was Quiet) when I switched the father out for another with a different nature.

But I don't have any hard evidence for this, so don't quote me on this.

The nature and characteristics of Pokémon are completely random, and they are in no way affected by the traits/characteristics of their parents. So, if there is a certain nature that you are seeking, you will just have to keep breeding your Pokémon until you happen to get a baby with the desired nature.

[AndrewPDes]

But! Number 1, do you have any proof? I think this calls for an experiment. Breed 100 pokemon, from parents that have identical natures. See how many come out of each natrue. Then we can mark this case closed.

Yes the parents do affect the offspring, for instance: Two machoke with a high Attack IV will have an offspring with a high Attack IV.

Actually, the passing down of DVs is random. Having parents that both have high DVs for a particular stat give you a greater chance of having a baby with a similar DV.

But besides, we're discussing natures here.

AndrewPDes: I try to have parents with a nature that raises the desired stat as a general rule. I can't guarantee anything good will come out of it, but it's a good way to start.

This is something I've been looking at for a while now, but it takes time to gather the data!

I can confirm the known rules that a baby will have 2-3 IV (usually 3; 2 IV only happens if it inherits the same stat from both) inherited from its parents, which can be any of the 6 stats from either parent.

Mood seems to be totally random - note that any random sequence WILL result in runs of the same value, and for a short sample this can seem to be a "rule". Batches of less than about 100 eggs from the same parents should be treated with caution. When I was testing to see if shinyness is inheritable (it doesn't seem to be) I bred 38 Swablu from a shiny Zubat (Mild) and a Swablu (Mild). Results:

3 Adamant
2 Bashful
3 Bold
2 Brave
2 Calm
4 Careful
2 Gentle
1 Hasty
1 Impish
1 Jolly
2 Lax
2 Lonely
1 Mild
1 Modest
1 Quiet
1 Rash
2 Relaxed
2 Serious
5 Timid

That's the biggest group I've had the patience to do so far. It would be better to research it on the emulator, since you can look up their hidden values, but that's not convenient for me (I'd rather play other games when I have PC time).

For the record, the formula the game uses to determine mood is to take the hidden pokémon number and simply do a modulus 25 operation (divide by 25 and use the remainder as your result). Since this is a 32 bit number, there is an *imperceptably slight* tendancy for pokémon to not have personalities 20-24 (Calm to Quirky) as 25 goes into 4294967295 171798691 times with a remainder of 20. For practical purposes, there is an even chance of getting any of the personalities in the wild, unless there are hidden biases we are unaware of (like time of day).




I have noticed a *possible* tendancy for babies to inherit some IVs more than others from a given set of parents, but to really test this will need large samples (100's). It is quite possible that the chance of a given IV being inherited by the baby is not totally random, but affected by the parent(s) mood or even their hidden pokémon number.

Could you please explain in detail how I can read the hidden values (e.g. IVs) of a pokemon using the emulator (VBA)?
Or is this somewhere documented?

It is really very tedious to use Rare Candys and look how the stat values change to calculate the IVs. Although the excel sheet from "Don't Run With Scizors" is very helpful.

Thanks.
