Which genotype would result in an individual with the dominant phenotype?

In classic genetics: AA or Aa for autosomal dominance; for sex-linked dominance, females will need XX or Xx, while males will need Xy
It gets more complicated with epistasis and other factors that modulate the genes.

∙ 6y agoA homozygous dominant genotype contains two dominant alleles. For example, in humans, being able to roll the tongue into a U shape is dominant, and not being able to roll the tongue is recessive. Lets assign the letter R for the dominant allele and the letter r for the recessive allele. A homozygous dominant individual would have the homozygous dominant genotype, RR.

What is an individual with genotype AAA described as?
An Aa genotype can result in the same phenotype as either an AA or AA genotype, if one of the alleles acts in a dominant fashion. If the A allele is dominant over the a allele, then the phenotype of a heterozygous (Aa) individual will be the same as the phenotype of a homozygous dominant (AA) individual.
To determine the genotype of an individual that shows the dominant phenotype you would cross that individual with one that is?
To determine the genotype of an individual that shows the dominant phenotype you would cross that individual with one that is homozygous recessive. A monohybrid cross of two individuals that are heterozygous for a trait exhibiting complete dominance would probably result in a phenotype ratio is 3 dominant 1 recessive.
What phenotype is produced by AB genotype?
The genotype AA represents a homozygous dominant genotype. The capital letter "A" represents the dominant allele, while the lowercase letter "a" would represent the recessive allele. If both dominant alleles are present in a genotype (homozygous dominant) then the phenotype is "A" phenotype. If one dominant allele and one recessive allele are present (heterozygous dominant) then the phenotype is "A". Finally, if both recessive alleles "a" are present (homozygous recessive) then the phenotype is "a". Therefore, the answer to your question is the genotype AA would result in an "A" phenotype because the genotype is homozygous dominant.
What Most of the traits expressed in a person phenotype are determined by?
the Phenotype is the direct result of the genotype and the environment...... genotype + environment = Phenotype
Is phenotype the way an organism looks and behaves a result of its genotype?
Yes. the phenotype is the visible manifestation of a genotype. In the example of fruit flies, if red eyes are dominant and white eyes recessive, than the genotypes "AA" and "Aa" will give a dominant phenotype of red eyes. Conversely, a recessive "aa" will give a phenotype of white eyes.

What are examples of a genotype and a phenotype?
Genotype relates to the genetic makeup of an individual, and refers to all the genes on your chromosomes, whereas phenotype refers to the physical attributes that exist as a result of the genotype. Taking eye colour as an example, your phenotype will be brown eyes, and your genotype will be the two genes (one from the sperm and one from the egg). Only one of these two genes (the dominant one) will contribute toward your phenotype.

How is genotype and phenotype compared?
Genotype is the allele combination and phenotype is the physical appearance of the result of the genotype. Genotype for tallness may be: Tt Phenotype example: Brown hair, blue eyes, widow's peak, etc.
How an organism looks as a result of its genotype is known as its?
Phenotype
Which of the following is the best definition of the term phenotype?
Genotype is the alleles (different forms of a gene) which an individual has with respect to a particular characteristic. The Phenotype is how these genes are expressed in an individual.
What an organism looks like as a result of a gene is called?
a phenotype is the physical characteristics of an organism based on its genotype.
What appearance of an individual due to its genetic makeup?
The observable trait that appears in an organism as a result of its genetic makeup is called a phenotype. Its underlying genetic makeup is referred to as the genotype.
What we call the observable expression of genes present in an organism?
When genes are expressed, the result is called phenotype. What is actually in all the genes (some are recessive) is called the genotype.
