Blending inheritance is an obsolete theory in biology from the 19th century. The theory is that the progeny inherits any characteristic as the ... Incomplete dominance;
Experiments on Plant Hybridization" (German: Versuche über Pflanzen-Hybriden) is a seminal paper written in 1865 and published in 1866 [1] [2] by Gregor Mendel, an Augustinian friar considered to be the founder of modern genetics. The paper was the result after years spent studying genetic traits in Pisum sativum, the pea plant.
Autosomal dominant and autosomal recessive inheritance, the two most common Mendelian inheritance patterns. An autosome is any chromosome other than a sex chromosome.. In genetics, dominance is the phenomenon of one variant of a gene on a chromosome masking or overriding the effect of a different variant of the same gene on the other copy of the chromosome.
Flowers of heterozygous plants have a phenotype somewhere between the two homozygous genotypes. In cases of intermediate inheritance (incomplete dominance) in the F 1-generation Mendel's principle of uniformity in genotype and phenotype applies as well. Research about intermediate inheritance was done by other scientists.

In cases of intermediate inheritance due to incomplete dominance, the principle of dominance discovered by Mendel does not apply.Nevertheless, the principle of uniformity works, as all offspring in the F 1-generation have the same genotype and same phenotype.
Very few phenotypes are purely Mendelian traits. Common violations of the Mendelian model include incomplete dominance, codominance, genetic linkage, environmental effects, and quantitative contributions from a number of genes (see: gene interactions, polygenic inheritance, oligogenic inheritance). [1] [2]
The effects of dominance and epistasis are not reliably transmitted to progeny (see Mendelian inheritance, laws of segregation and independent assortment). This means that h 2 represents the phenotypic variation that is reliably passed from one generation to the next and which can be used to predict changes in mean fitness between generations.
