Additive gene action is estimate of the quantitative change in a trait.

Additive effect= mean of superior parent - mean of inferior parent

Dominace effect = Mean of F1 hybrid - mean of both parent

Epistatic = additive x additive

= additive x dominace

= dominace x dominace

Additive : halogenated additive

Filler : Aluminium Hydroxide (ATH)

The additive inverse of a number is that which when added to the number gives 0.

If n is a number then the additive inverse of it (-n) is that number such that:

n + -n = 0

For example, the additive inverse of '4' is '-4'.

-3

The opposite of a number.
