Fill in the table: Types of gene interaction of one allelic pair

Interaction type The nature of the interaction in the
heterozygous state
The phenotype cleavage formulas in F and in analyzing crosses Examples
Complete dominance One allele (dominant) completely suppresses the effect of another (recessive) allele 3: 1 (1: 1) Tall plant growth dominates dwarfism; curly hair – over straight; brown eyes – over blue, etc.
Incomplete dominance The action of each allele is not fully realized, as a result of which an intermediate sign appears 1: 2: 1 (1: 1) Coloring flowers of a night beauty; sickle cell anemia; cystururia, etc.
Coding The participation of both alleles in the definition of a trait 1: 2: 1 (1: 1) Blood group IV (red blood cells of this blood group have agglutinogens of type A and type B )
