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.

What information would tell you if a cross showed complete dominance?
If a cross between two organisms shows complete dominance, all individuals in the first generation (F1) will display the dominant trait. This indicates that the dominant allele is fully expressed, masking the recessive allele. To confirm complete dominance, further crosses involving the F1 generation can be conducted to observe the phenotypic ratio of the offspring.
What type of dominance do pew plants show?
complete dominance....
When one allele shows dominance over another allele?
In cases of complete dominance, one allele, known as the dominant allele, masks the expression of the other allele, known as the recessive allele, in the heterozygous state. This results in only the dominant allele being expressed in the phenotype.
What is the term for dominance in which the dominant allele is always expressed?
Complete dominance
What trait in reebops blends and shows incomplete Dominance?
In reebops, the trait that blends and shows incomplete dominance is the color of their bodies. For example, if one parent contributes a gene for pink coloration and the other for blue, the offspring may exhibit a purple hue, representing a blend of both traits rather than a distinct dominance of one color over the other. This results in a mixed phenotype that demonstrates the concept of incomplete dominance in genetics.
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 is an example of a black mouse being crossed with a white mouse and all the offspring produced was gray?
Incomplete dominance
What trait in reebops blends and shows incomplete Dominance?
In reebops, the trait that blends and shows incomplete dominance is the color of their bodies.

This results in a mixed phenotype that demonstrates the concept of incomplete dominance in genetics.
What is and example of in complete dominance?
Complete 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 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.
