polygenic inheritance
codominance
Alleles are genes that exist in multiple forms.
In Mendelian inheritance the allele has a one to one effect on the phenotype. A polygenic effect is given when many genes contribute in an additive fashion to the phenotype. Height is such and may have as many as eight genes contributing to the effect. Behavior is also of this type. Eye color is more Mendelian in nature.
The terms used to describe a number of genes on separate loci on the same chromosome (or another chromosome) which together determine a single phenotypic trait are polygene, multiple factor, multiple gene inheritance or quantitative gene.

the difference is that a polygenic character is is influenced by several genes and they show many variation, complex characters are influences strongly the environment and genes.
each and every step of individual behaviour is influenced by the genes and the behaviour of the parents and so itisclearthat heredity plays a major part of ones life
If you are a teenager and have Multiple Sclerosis in your genes you can read books to enjoyment.
The genes which have more than one alleles are called multiple allelic genes and this phenomenon is known as multiple allelism.

"Heterozygus" and homozygus" are adjectives that describe the relationship of genes, they are not genes themselves.

Human behavior is made up of hormones which may be part of the genetic make up of heredity. Heredity is something that is already in your genes. It just appears one day, but it has always been there.But hormones can be an uncontrollable chemical balance in a person diet, weight, and life style that cause the body to send unusual message to the brain causing you to react different depending on the circumstances.
