Is the blending of inheritance similar to incomplete dominance

2. Important terms in classical genetics

Classical Genetics: Definitions of Terms
The Mendelian rules (Laws of inheritance) describe Laws of Inheritance of features.
GenesHereditary factors. They contain information in the form of specific base sequences that are translated into proteins and thus functional or active (pronounced / expressed) (see protein synthesis as a function of DNA).

AllelesVariants of a gene (e.g. flower color: allele "red" and allele "white"). There can be more than two variants of information. One then speaks of multiple allelia (e.g. for blood groups).

Phenotype = Appearance (e.g. visible flower color) = visible characteristics. When a "trait" (phen) is spoken of, the phenotypic expression (expression) of a gene is meant.

genotype = Inheritance (genetic disposition, e.g. for flower color) = totality of genetic characteristics.

diploid = double set of chromosomes; for each trait (phen) there are two genes. In higher animals and plants, all cells with the exception of the sex cells are diploid (or polyploid = even more sets of chromosomes)
Danger! Do not confuse this with the replicated set of chromosomes! See replication before mitosis!

haploid = simple set of chromosomes; for each trait there is (only) one genetic disposition (or one gene). Arises from reduction division (meiosis). Occurs in the sex cells: egg cell, sperm. The fusion during fertilization then creates a diploid set of chromosomes again.
pure (homozygous) = The diploid chromosome set stands for a purely inherited trait the same genetic make-up in both sets of chromosomes (e.g. 2 x flower color "red"). An individual happens to inherit the same gene variant (the same allele) from both parents.
mix-and-match (heterozygous) = In the diploid set of chromosomes there is a mixed-blood trait two different genes (e.g. flower color "red" AND "white")
dominant-recessive inheritance = For mixed-inherited characteristics one genetic trait prevails over the other (e.g. flower color "red" dominant compared to the recessive "white": genotype = red and white / phenotype = red)
intermediate inheritance = In the case of mixed-inheritance traits, both hereditary factors (alleles) influence and lead to an "intermediate" = intermediate appearance of the trait due to incomplete dominance (e.g. flower color "red and white intermediate": genotype = red and white / phenotype = pink). Both alleles influence the expression (expression).
codominant inheritance = With codominant inheritance patterns, both hereditary factors influence the relevant trait to the same extent. Both hereditary factors are fully expressed (e.g. blood group AB - the gene for surface protein A and the gene for surface protein B are both fully expressed and thus both proteins are on the red blood cells: AB).
monohybrid inheritance = The Inheritance of a trait is examined (e.g. flower color)
dihybrid inheritance = The Inheritance of two characteristics is examined (e.g. pea color and shape)
Parental generation (P) = parents
First generation of branches (F1) = daughter generation after crossing the P generation
Second generation of branches (F2) = grandchildren after crossing the F1 generation
Mixed race (Bastards, hybrid) = F1 generation with mixed (intermediate) genotype
Gamet = Sex cell (sperm cell, egg cell)
Backcross = Crossing the mixed-blooded F1 generation with the pure-blooded P generation. Initial situation: There is a dominant phenotype = e.g. only the flower color that is considered "dominant" is visible. The genotype of this individual can be both RR (= homozygous) and Rw (= heterozygous). In order to find out whether it is a homozygous or heterozygous genotype for the characteristic "flower color", the backcrossing is carried out with an organism that is clearly recessive-homozygous for the characteristic "flower color", ie genotype: ww.
