Intermediate Inheritance

What is an intermediate inheritance? Definition and example:

Genotypes related to genotype and phenotype are classified into three different forms. A distinction is made between dominant-recessive, codominant and intermediate heredity.

While in dominant-recessive inheritance only one trait, and in codominanten inheritance both features in the phenotype appear in appearance, intermediate inheritance characterized by a mixed form of both alleles. In the specific case, this means that neither the one nor the other allele in the first branch generation occurs phenotypically. This becomes clear in the following example: In the crossing of two differently colored flowers (white and red) with intermediate inheritance, it comes in the first branch generation (F1 generation) consistently to a new pink intermediate form.

If one thinks of this further example, then in the second branch generation (F2 generation) in the sense of the fission rule in the ratio 1 (homozygous red) to 2 (heterozygous pink) to 1 (homozygous white), all three phenotypes would appear.

Incidentally, the term "intermediate inheritance" derives from Latin (lat: inter = between; medius = lie;) and means "intervening".

Summary

In the case of intermediate heredity or an intermediate heredity, there is a mixed characteristic of at least two different alleles.

If two different colored flowers are crossed in an intermediate inheritance, all the flowers in the F1 generation show the hybrid form. In the F2 generation, all three phenotypes occur in the ratio 1: 2: 1.
