what do we call factors that control traits
The factor that controls the traits of an organism is called DNA. Within the DNA there are codes for different genes that are either turned on or off.
gene
Genes are factors that control a trait.

Genes.
genes
the plant has 2 factors for each possible trait one for each parent
yes it's true
Multifactorial inheritance describes the situation were more than one gene affects a single trait. Environmental factors can also contribute to the single trait.
Phenotypes
It is called a dominant trait
the plant has 2 factors for each possible trait one for each parent
yes it's true
Multifactorial trait
A multifactorial trait, a polygenic trait commonly influenced by the environment.
Polygenic
yes its called pleiotropy
the offspring have two factors for each trait
A "trait" such as tall/short or round/shrivelled (in relation to pea plants Mendelian genetics) is determined by which allele or version of the gene is inherited by the offspring.
The presence of more than two alleles that control a trait is called multiple allele. An example of this is the group gene of ABO blood that has three alleles.
invisible "factors" - now called genes.
They are called alleles. Each allele is a different form of the gene, and they can be dominant or recessive.
A trait that masks another trait is called a dominant trait. This means that when an organism carries both dominant and recessive alleles for a particular gene, only the dominant trait will be expressed in the phenotype.
