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 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.
What is the expected phenotype ratio of seed color of the offspring of an F1 x F1 cross?
If the parents were AA and AA for example then the phenotype ratio will be 1 A (the dominant allele). The genotype will be 1Aa.
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.
Phenotype can be affected by genotype and what?
Phenotype is the way a specific trait is displayed by the organism. Genotype is all the genetic information present at the gene locus on the chromosome pair. If the phenotype is recessive the genotype will be designated by two lower case letters. Ex. aa is black If the phenotype is dominant the genotype could be designatedtwo upper case letters or one upper case and one lower case letter. Ex. Aa or AA is red.
What phenotype is produced by AA genotype?
If A represents a dominant allele, then the AA genotype would produce the dominant phenotype.
Is Aa and AA a dominant phenotype?
Yes, both Aa and AA genotypes represent the dominant phenotype for a specific trait. The presence of at least one dominant allele (A) will result in the dominant phenotype being expressed.
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.
If AA is dominant for a widow's peak and if a child is born without a widow's peak what is his phenotype?
The Phenotype would be a straight hairline. The genotype would be aa.
How is the phenotype determined by the genotype?
Ex. Genotype = Phenotype AA Pure, no cleft chin Aa Hybrid, no cleft chin AA Pure, cleft chin XX Female XY Male
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.
What is the expected phenotype ratio of seed color of the offspring of an F1 x F1 cross?
If the parents were AA and AA for example then the phenotype ratio will be 1 A (the dominant allele). The genotype will be 1Aa.
What is a phenotype on a punnet square?
It is the observable trait that will be present. If the genotype is AA (A being brown eyes, a being blue), the person's phenotype would be brown eyes. For Aa, it would also be brown eyes. For aa, it would be blue eyes.
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 phenotype is produced by BO?
B
What are the phenotypes of two dominant alleles?
When taking two alles as A and a. They are AA and Aa
What is the phenotype produced between the two homozygous parents?
The same phenotype as both of the parents.
