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
A delayed-action gene is a gene that takes time to go into effect. Examples of a delayed-action gene are puberty and greying hair.
additive
Gene action refers to the way genes interact to determine a specific trait. In plant breeding, understanding gene action is important for predicting the outcomes of crosses and selecting for desired traits. By studying gene action, breeders can make informed decisions about which plant lines to cross to achieve the desired characteristics in new varieties.
When a group of gene pairs act together, they can have a synergistic effect where their combined action results in a greater impact than each gene individually. This coordinated action is essential for many biological processes, such as development, metabolism, and response to environmental stimuli. Dysregulation of gene pairs working together can lead to disease or abnormal phenotypes.

When more than one gene controls the expression of a trait, it is known as polygenic inheritance. Each gene may contribute a small amount to the phenotype, leading to a wide range of possible variations. This can result in continuous variation in the trait rather than distinct categories.
what is dominant of genne action
A delayed-action gene is a type of gene that is expressed after a certain period of time has passed or when triggered by specific environmental conditions. This gene regulation allows organisms to respond to changing conditions by activating or deactivating certain genetic functions at a specific time.
Phenotype
Gene action refers to the way genes interact to determine a specific trait. In plant breeding, understanding gene action is important for predicting the outcomes of crosses and selecting for desired traits. By studying gene action, breeders can make informed decisions about which plant lines to cross to achieve the desired characteristics in new varieties.
because the behr cannot respond quick Edited answer: During hybridization additive gene action from the two parents result in heterosis which ultimately increases food production in crop plants.
