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.

∙ 11y agoComplete dominance is when the presence of one allele ensures that the trait of the other allele is not displayed.
For example, if B codes for black fur and b codes for white fur, a rabbit with Bb will have black fur. This is because the B shows complete dominance over the b - meaning that black fur will result.
If this was incomplete dominance, a rabbit with Bb would have a mix - so grey fur.
If it was codominance, a rabbit with Bb would have black and white patches, dots or splotches.

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.
How many alleles influence a phenotype in complete dominance?
8
Is it easier to analyze genotype by observing phenotype in organisms with complete dominance or in organisms with incomplete dominance?
It is easier to analyze genotype by observing phenotype in organisms with incomplete dominance (also known as codominance), because in incomplete dominance the individual will show a specific phenotype for each situation, whether it is homozygous dominant, heterozygous, or homozygous recessive. For example, in flowers, such as the ones that Mendel studied, a homozygous dominant flower will be red, a homozygous recessive flower will be white, and a heterozygous flower will be pink. In complete dominance, a heterozygous will only express the dominant phenotype, as opposed to incomplete dominance, in which a heterozygous individual will express a phenotype that is representative of both of the dominant and recessive traits. Because heterozygous individuals in complete dominance express the dominant phenotype, it is hard to determine whether the genotype is homozygous dominant or heterozygous for the trait. Hope this helps!

Example of incomplete dominance?
An example of incomplete dominance is when a white flower and red flower mate and create a pink flower. The white and red colors mix creating the pink. Neither allele is dominant, resulting in a combination of the two.
What does total dominance of one allele mean?
Total dominance is just another way of saying complete dominance. It is basically when one allele takes over the other
