Incomplete Dominance
incomplete dominance
The type of inheritance that involves one dominant allele and one recessive allele is called simple Mendelian inheritance or complete dominance. In this pattern, the phenotype of the organism will display the trait associated with the dominant allele, while the recessive allele's effects are masked when both alleles are present. An example of this is the inheritance of flower color in pea plants, where purple (dominant) flowers mask the expression of white (recessive) flowers.

Incomplete dominance is not a mutation; it is a type of genetic inheritance pattern where neither allele is completely dominant over the other. Mutations, on the other hand, are changes in the DNA sequence that can result in altered traits or functions.
In this inheritance pattern, a cat with at least one dominant allele (B) will have a brown coat, while only cats with two recessive alleles (bb) will display a white coat. Therefore, the possible genotypes for a brown-coated cat are either homozygous dominant (BB) or heterozygous (Bb). In contrast, a cat with a white coat must have the homozygous recessive genotype (bb). This demonstrates classic Mendelian inheritance with the dominant brown allele masking the expression of the recessive white allele.

Codominance
Pleiotropy is the term used to describe an inheritance pattern where a single allele affects multiple phenotypic traits. In this pattern, one gene is responsible for controlling or influencing multiple aspects of an organism's phenotype.
The type of inheritance that involves one dominant allele and one recessive allele is called simple Mendelian inheritance or complete dominance. In this pattern, the phenotype of the organism will display the trait associated with the dominant allele, while the recessive allele's effects are masked when both alleles are present. An example of this is the inheritance of flower color in pea plants, where purple (dominant) flowers mask the expression of white (recessive) flowers.
Codominance is a genetic inheritance pattern where both alleles for a trait are fully expressed in the phenotype of an individual. This means that neither allele is dominant or recessive, and they both contribute to the observable trait. In contrast, in other forms of genetic inheritance, such as complete dominance or incomplete dominance, one allele may be dominant over the other, leading to a different expression of the trait.
