No. If you think of some of the dominant human phenotypes, you'll notice they are uncommon (or even very rare). Examples are sexydactyly (six fingers/toes), Huntington's chorea, photic sneezing, widow's peak, cheek dimples, cleft chin, and achondroplasia (the most common form of dwarfism). The reason is because the dominant alleles that cause these phenotypes are uncommon in our gene pool.
What else can I help you with?
How many phenotypes does the trait have?
Aa AA aa If A dominant, two phenotypes.
Why isn't it possible to have more genotypes than phenotypes?
I think you have the question backwards, "Why isn't it possible to have more phenotypes than genotypes?" There are always more or an equal number of genotypes relative to phenotypes. The phenotype for a simple dominant/recessive interaction (for example) T for tall and t for short where TT is tall, Tt is tall and tt is short has three genotypes and two phenotypes. If T and t are co-dominant then TT would be tall, Tt would be intermediate and tt would be short. (Three phenotypes and three genotypes.)
Why phenotypes don't always express its entire genotype?
Phenotypes are the entirety of the observable traits. Genotypes are the instructions in the genetic code. Dominant alleles override the recessive alleles, making only the dominant alleles expressed.
What are the phenotypes of two dominant alleles?
If two alleles are dominant, the phenotypes will reflect the dominant traits associated with each allele. Both alleles will be expressed in the phenotype, resulting in a phenotype that shows the dominant characteristics of both alleles.
Recessive allele is more common or dominant allele?
Not necessarily. I think the dominant genes are more common, but there are lot of exceptions out there. For example, having six fingers in humans is a dominant gene, but it isn't all that common.
Which genotypes have dominant phenotypes?
The genotypes in which one or more alleles is dominant.

What Does the phenotypic distribution look like in a population that is not undergoing natural selection for a certain trait?
The distribution will center towards hetrotrophs and thus dominant phenotypes. The distribution approaches all dominant phenotypes

Why phenotypes more common in a population than others?
Phenotypes that are more common in a population often arise due to natural selection, where traits that confer a survival or reproductive advantage become more prevalent over generations. Additionally, genetic drift can influence the frequency of certain phenotypes, especially in small populations, while gene flow can introduce or reinforce specific traits. Environmental factors and adaptations to local conditions also play a crucial role in shaping which phenotypes dominate. Ultimately, the interplay of these factors leads to the varying frequencies of phenotypes within a population.
The outward appearance of a particular trait is called?
The outward expression of genetic traits are called phenotypes. Phenotypes expression include recessive and dominant genes such as eye and hair color.
What was the ratio of dominant to recessive phenotypes in the F2 generation of Mendel's experiments?
(Apex Learning) 3:1.
What is an example of a dominant human trait?
Dominant traits are more common. For example, brown hair and eyes are good examples of dominant traits. Another example of a dominant trait are your earlobes! Free earlobes are more common than attached earlobes.
What are the possible phenotypes of the off-spring from the cross of the parental plants in problem no.1?
To accurately determine the possible phenotypes of the offspring from the cross of the parental plants, I would need specific details about the traits and genotypes of the parental plants in problem no.1. Generally, if the traits follow Mendelian inheritance, the offspring's phenotypes can be predicted based on the dominant and recessive alleles present in the parents. For example, crossing a homozygous dominant plant with a homozygous recessive plant would typically yield all heterozygous offspring displaying the dominant phenotype. Please provide more context or details about the parental plants for a precise answer.
