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 ultimately determines the phenotype of an individual?
Phenotype is what traits are expressed by the organism. So what ever is the dominant Genotype of the organism will determine the Phenotype. For example a dominant R gene will be the Phenotype in RR and Rr. However, if the organism has two recessive rr then the recessive gene will determine the Phenotype.
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.
How do you use genotype and phenotype in a sentence?
In genetics,the phenotype is when genes combine to determine dominant traits
When would a pedigree be better to use to deterimine the genotype of an individual instead of a testcross?
n genetics, a test cross, first introduced by Gregor Mendel, is used to determine if an individual exhibiting a dominant trait is homozygous or heterozygous for that trait. More simply put, test crosses determine the genotype of an individual with a dominant phenotype.
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.
Breeding an individual of dominant phenotype with a homozygous recessive individual to determine the individuals genotype?
testcross

Is phenotype determine genotype false?
Yes, this is false. It's genotype that determines phenotype. e.g. If you have the dominant gene for brown eyes and the recessive gene for blue eyes (genotype) you will have brown eyes (phenotype)
Why is it sometimes impossible to determine the genotype of an organism that has a dominant phenotype?
it is impossible because the phenotype and genotype are different this is out of chapter 10 in the biology book on page 336

What phenotype is produced by AA genotype?
If A represents a dominant allele, then the AA genotype would produce the dominant phenotype.
What are an individual's observable traits called?
genotype or phenotype
Does phenotype determine genotype?
It is a false statement that "phenotype determines genotype". In fact, it is the opposite. A genotype is the genetics or "instructions" that determine the phenotype. The phenotype is the actual appearance, ex: blue eyes, that is created by a given genotype.
