Mendelian inheritance refers to an inheritance pattern that follows the laws of segregation and independent assortment in which a gene inherited from either parent segregates into gametes at an equal frequency.

CLASSIC RATIO

2. happens when on allele is not completely dominant over
the other allele. Incomplete dominance often shows a
heterozygous phenotype that is intermediate between
the two homozygous phenotypes. Alleles of a gene are
partially expressed in an intermediate phenotype.
INCOMPLETE
DOMINANCE
The colour violet shows incomplete dominance.
Example:
If a plant has both a recessive and dominant gene,
it will be a mix of purple and white (violet).

3. In this principle, both alleles contribute to
the phenotype of an organism. Both
alleles of a gene are distinctly expressed.
Example:
Purple and white shows codominance.
If a plant has both a recessive and dominant gene, it
will be purple with white spots.
