Complete dominance is when the F1 offspring look like one of the two parents. Incomplete dominance is when neither allele for a gene is completely dominant over the other which leads to a phenotype (physical look or characteristic) somewhere between the two parents. An example of complete dominance would be in Mendel's classic pea cross experiment, with yellow peas being dominant to green peas. More peas would be yellow than green. An example of incomplete dominance would be with snapdragons. If a red true breeding snapdragon were crossed with a white true breeding snapdragon, the F1 generation offspring would all be pink, because neither the 'red' allele nor the 'white' allele was completely dominant over the other leading to a hybridization in color somewhere between the two parents.

What is the opposite of incomplete dominance?
The opposite of incomplete dominance is complete dominance. In complete dominance, one allele completely masks the effect of another allele at the same locus, resulting in a phenotype that reflects only the dominant allele. For example, in a complete dominance scenario, a plant with a dominant allele for flower color will exhibit that color, while the recessive allele has no visible effect on the phenotype.
What type of dominance do pew plants show?
complete dominance....
What is the term for dominance in which the dominant allele is always expressed?
Complete dominance
What is the results when two different alleles both appear in the phenotype?
When one allele for a particular trait masks or overrides another allele for a trait, it is called dominance. The allele that is masked is called the recessive allele. The allele that is dominant will determine the phenotype.
Which example shows complete dominance?
Complete dominance occurs when one allele completely masks the effect of another allele at the same gene locus. An example of this is the inheritance of flower color in pea plants, where the allele for purple flowers (P) is completely dominant over the allele for white flowers (p). In this case, both homozygous (PP) and heterozygous (Pp) plants will exhibit purple flowers, while only homozygous recessive (pp) plants will show white flowers. This clear masking of one allele by another is a hallmark of complete dominance.

This clear masking of one allele by another is a hallmark of complete dominance.
What are the three types of dominance?
The three types of dominance are complete dominance, incomplete dominance, and codominance. In complete dominance, one allele is fully expressed over another. In incomplete dominance, neither allele is completely dominant, resulting in a blending of traits. In codominance, both alleles are expressed equally, leading to a distinct phenotype that shows features of both alleles.
What does total dominance of one allele mean?
Total dominance of one allele means that the phenotype associated with that allele is expressed in the heterozygous condition, masking the phenotype of the other allele. This is also known as complete dominance.
How many alleles influence a phenotype in complete dominance?
