What type of alleles are present in an organism?
Capital letters usually denote dominant alleles. Therefore QQ genotype would contain two dominant alleles for the Q genotype.
What type of genotype has two dominant alleles such asBB?
A genotype with two dominant alleles, such as BB, is referred to as homozygous dominant. In this case, both alleles for a particular gene are the same and dominant, which typically results in the expression of the dominant trait. Individuals with a homozygous dominant genotype will exhibit the dominant phenotype associated with that gene.
What type of inheritance when the genotype is neither homozygous or heterozygous?
When the genotype is neither homozygous nor heterozygous, it typically indicates incomplete dominance or codominance. In incomplete dominance, the two different alleles are neither dominant nor recessive, resulting in a blending of phenotypes. In codominance, both alleles are expressed fully in the phenotype, leading to distinct traits from each allele being visible.
What is the a blood type for alleles?
Blood type is determined by the presence of specific alleles for the ABO blood group system. There are three main alleles: A, B, and O. The A and B alleles are co-dominant, meaning that if both are present (genotype AB), both antigens are expressed on the red blood cells. The O allele is recessive, so an individual must have two O alleles (genotype OO) to express the O blood type.
What possible blood genotype would give group o?
There is only one possible blood genotype that gives group O. The person must be homozygous for type O.

What is the difference between a homozygous individual and a heterozygous individual?
In genetics, homozygous genes are identical alleles, while heterozygous genes have different alleles. For example, TT(same alleles) is homozygous genotype, while Tt (different alleles) is a heterozygous genotype.
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 type of gene has Identical alleles?
A homozygous gene has identical alleles. Homozygous means the individual has two copies of the same allele for a particular gene.
The type of genotype where the alleles are not the same?
Hybrid
What type of inheritance when the genotype is neither homozygous or heterozygous?

In incomplete dominance, the two different alleles are neither dominant nor recessive, resulting in a blending of phenotypes. In codominance, both alleles are expressed fully in the phenotype, leading to distinct traits from each allele being visible.
What are some genotype examples?
A Phenotype, physical appearance.
What type allele are present in an organism with a QQ genotype?
Capital letters usually denote dominant alleles. Therefore QQ genotype would contain two dominant alleles for the Q genotype.
What is the type of allele that only effect the phenotype in the homozygous chromosome?
Recessive. Dominant alleles are expressed in both homozygous and heterozygous individuals (DD or Dd), but recessive alleles are only expressed in homozygous individuals (dd).
What is homozygous recessive genotype?
variation in alleles of genes, occurs both within and among populations. Genetic variation is important because it provides the genetic material for natural selection. Genetic variation is brought about by mutation, which is a permanent change in the chemical structure of a gene. Polyploidy is an example of chromosomal mutation. Polyploidy is a condition wherein organisms have three or more sets of genetic variation (3n or more).
What is number of gamete types in the genotypes below AA AA AA?
In the given genotype, which consists of three identical homozygous alleles (AA), there is only one type of gamete that can be produced. Since all alleles are the same (A), the only gamete type formed would carry the A allele. Therefore, the number of gamete types is one.
