The pattern of inheritance in which both alleles contribute to the phenotype of the organism is codominance. For example white and red hair color in cattle. Black and white feather color in certain chickens.
Non-dominant or co-dominant or incomplete dominance are terms associates with intermediate phenotypes displayed by heterozygotes.
Codominance
codominance
dominant
This type of inheritance represents alleles at the same locus where one is recessive to the other. The dominant phenotype occurs in all heterozygous offspring as well as the homozygous dominant offspring. This yields a 3:1 phenotype and a 1:2:1 genotype.
In humans, height is governed by polygenic inheritance, which means that many different genes contribute to a person's height, rather than just one.
Polygenic inheritance shows a continuous variation. An example of polygenic inheritance is human skin because it has a variety of colors. An example of something not having polygenic phenotype is earlobes because they are either free or attached; there is no in-between state.
Males are only going to have one X chromosome, so they will either show the phenotype or be normal. Girls will either be carriers or normal.
polygenic inheritance is when more than one genes are responsible for a character/phenotype. for example human skin color. if one want to draw a pedigree for that, he will not be able to succeed. although individual genes at molecular level is inherited according to mendel's laws. and mendelian inheritance simply follows mendels laws. also the character is controlled by one gene only. for example pea plant height.

Gregor Johann Mendel is credited with discovering the pattern of genetic inheritance

A 3:1 phenotypic ratio (Mendelian inheritance).
No, recessive traits refer to the inheritance pattern of the allele. In the simple case where a trait is either expressed or not, if it is a recessive trait it will only be the expressed phenotype when it is homozygous. Dominant allele phenotypes will show if the genotype is heterozygous.
Types of dominance, multiple alleles, sex linked inheritance, polygenic inheritance and maternal inheritance.
polygenic inheritance is when more than one genes are responsible for a character/phenotype. for example human skin color. if one want to draw a pedigree for that, he will not be able to succeed. although individual genes at molecular level is inherited according to mendel's laws. and mendelian inheritance simply follows mendels laws. also the character is controlled by one gene only. for example pea plant height.
