The observable characteristic expressed as a result of an allele pair is referred to as a phenotype. The phenotype is influenced by the interaction of the organism's genotype (the specific alleles present) with environmental factors. For example, in pea plants, the phenotype can include traits such as flower color or plant height, which are determined by the underlying genetic information.

What are is an observable characteristic that is expressed as a result of an allele pair?
An observable characteristic that is expressed as a result of an allele pair is called a trait. Traits can be physical features (such as eye color or height) or functional characteristics (such as blood type or enzyme production) that are influenced by the interaction of alleles in the individual's genotype.
What is the difference between a gene allele Chromosome and trait?
Alleles are alternate versions of genes that code for certain phenotypes, or traits. The traits of an individual are a result of the interaction between their genotype (alleles) and the environment.
What is the observable characteristic of an organism called?
The observable characteristic of an organism is called a "phenotype." This includes traits such as physical appearance, behavior, and physiological properties, which result from the interaction of its genotype with the environment. Phenotypes can vary widely within a species and are influenced by genetic and environmental factors.
What is An allele or trait that exerts a controlling influence?
An allele or trait that exerts a controlling influence is known as a dominant allele. This type of allele can mask the expression of a recessive allele when both are present in an organism's genotype. As a result, the trait associated with the dominant allele will be expressed in the phenotype, while the recessive trait may not be observed. Dominance is a key concept in genetics, influencing inheritance patterns in organisms.
What word is used to describe an observable trait or characteristics?
The word used to describe an observable trait or characteristic is "phenotype." Phenotype refers to the physical characteristics or traits of an organism that result from the interaction of its genetic makeup (genotype) with the environment.
What are is an observable characteristic that is expressed as a result of an allele pair?
An observable characteristic that is expressed as a result of an allele pair is called a trait. Traits can be physical features (such as eye color or height) or functional characteristics (such as blood type or enzyme production) that are influenced by the interaction of alleles in the individual's genotype.
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 is the result when a dominant allele pairs up with a recessive allele in simple dominance?
The dominant form of the trait shows. -Gradpoint
What is the difference between a gene allele Chromosome and trait?
Alleles are alternate versions of genes that code for certain phenotypes, or traits. The traits of an individual are a result of the interaction between their genotype (alleles) and the environment.
How is incomplete dominance expressed in a phenotype and what are the observable characteristics that result from this genetic phenomenon?
Incomplete dominance is a genetic phenomenon where neither allele is completely dominant over the other, resulting in a blending of traits in the phenotype. This means that the observable characteristics in an individual with incomplete dominance will be a mix of the traits from both alleles, rather than one trait being dominant over the other.
What is the observable characteristic of an organism called?
The observable characteristic of an organism is called a "phenotype." This includes traits such as physical appearance, behavior, and physiological properties, which result from the interaction of its genotype with the environment. Phenotypes can vary widely within a species and are influenced by genetic and environmental factors.
What is the alternative forms or genetic information for a trait are called?
This is generally the definition of an allele. An allele is an "alternate form of a gene". For each gene there may be many alleles. For example (simplistically) the gene which makes the pigment in your eyes (ie which gives you your eye colour) has a brown, green and blue allele. On each of the two chromosomes (one from your mother and one from your father) you can have either the same allele (homozygous) or a different allele (heterozygous). In the case of a heterozygous gene the dominate allele is expressed. In some cases (co-dominance) both alleles are expressed.
Why is the genotype of the guinea pig with black fur expressed as (B)?
The genotype of the guinea pig with black fur is expressed as (B) because it represents the dominant allele for fur color. In genetic notation, uppercase letters indicate dominant traits, while lowercase letters represent recessive traits. Since black fur is a dominant characteristic, the presence of at least one (B) allele will result in the expression of that trait, regardless of the other allele's state. Thus, a guinea pig with the genotype (BB) or (Bb) will both display black fur.
What is An allele or trait that exerts a controlling influence?
An allele or trait that exerts a controlling influence is known as a dominant allele. This type of allele can mask the expression of a recessive allele when both are present in an organism's genotype. As a result, the trait associated with the dominant allele will be expressed in the phenotype, while the recessive trait may not be observed.

How many dominant alleles do you need to inherit that particular characteristic eg brown eyes?
To express a dominant characteristic, such as brown eyes, you need at least one dominant allele. In a diploid organism, which has two alleles for each gene (one inherited from each parent), possessing either one or two copies of the dominant allele will result in the expression of that trait. Therefore, having just one dominant allele (heterozygous) is sufficient to exhibit the dominant characteristic.
What is a variation of a gene that occurs at the same place on homologous chromosomes?
An allele is a variation of a gene that occurs at the same place on homologous chromosomes. Alleles can differ in their DNA sequence and can result in different traits or characteristics being expressed.
