- Alleles are different forms of a gene that can occupy the same position on homologous chromosomes.
- Alleles can be dominant or recessive, influencing the expression of a particular trait in an individual.
- Diploid organisms inherit two alleles for each gene, one from each parent, which can be the same (homozygous) or different (heterozygous).

An allele that is dominated or cover up by another allele is called what?
An allele that is dominated or covered up by another allele is called a recessive allele. This means that the trait associated with the recessive allele is only expressed when an individual carries two copies of that allele.
What is the alternate form of a gene?
The answer is allele
When on e allele of a gene masks the presence of the other allele what form is masked?
The recessive allele.
What is a dominent allele?
A dominant allele is a version of a gene that, when present, will always be expressed in the organism's phenotype, overriding the presence of a recessive allele. This means that if an individual inherits one copy of a dominant allele and one copy of a recessive allele for a particular gene, the dominant allele will determine the observable trait.
When allele of a gene masks the presence of the other allele what form can be seen in the phenotype?
When one allele for a particular trait masks or overrides another allele for a trait, it is called dominance. The allele that is masked is called the recessive allele. The allele that is dominant will determine the phenotype.
What is allele masked by the dominant allele?
An allele that is masked by the dominant allele is called a recessive allele. When an individual has one dominant allele and one recessive allele, only the trait determined by the dominant allele will be expressed. The recessive allele will only be expressed if an individual has two copies of it (homozygous recessive).
Allele that prevents the expression of a recessive allele?
A dominant allele
An allele that is dominated or cover up by another allele is called what?
An allele that is dominated or covered up by another allele is called a recessive allele. This means that the trait associated with the recessive allele is only expressed when an individual carries two copies of that allele.
What is the alternate form of a gene?
The answer is allele
When on e allele of a gene masks the presence of the other allele what form is masked?
The recessive allele.
Is albinism controlled by a dominant allele or by a recessive allele?
Recessive allele.
What is an expressed allele in a heterozygote?
Dominant allele as opposed to recessive allele.
What is an allele that always shows up in an organism's phenotype called - an allele that masks the other allele?
An allele that always shows up in an organism's phenotype and masks the expression of another allele is called dominant. Dominant alleles are always expressed, even when paired with a recessive allele.
Does a recessive allele need another recessive allele to be expressed?
Yes, a recessive allele needs to be paired with another recessive allele in order to be expressed. This is because recessive alleles are only expressed when an individual has two copies of the recessive allele, one from each parent. If an individual has one dominant allele and one recessive allele for a particular trait, the dominant allele will be expressed.
Alternative versions of a gene?
Alternative versions of a gene are called alleles. Alleles are different forms of a gene that can result in distinct traits or characteristics. These variations in alleles contribute to genetic diversity within a population.
What is a dominent allele?
A dominant allele is a version of a gene that, when present, will always be expressed in the organism's phenotype, overriding the presence of a recessive allele. This means that if an individual inherits one copy of a dominant allele and one copy of a recessive allele for a particular gene, the dominant allele will determine the observable trait.
When allele of a gene masks the presence of the other allele what form can be seen in the phenotype?
When one allele for a particular trait masks or overrides another allele for a trait, it is called dominance. The allele that is masked is called the recessive allele. The allele that is dominant will determine the phenotype.
