How does an allele trait in an organism?
An allele causes a trait by either being dominant orrecessive or example, allele A will occur over allele a because it is dominant.
Is it proper to put the dominant allele before a recessive allele when determining the genotype?
Yes, it is common practice to denote the dominant allele before the recessive allele when writing a genotype to highlight the dominant trait. For example, if the dominant allele is represented by "A" and the recessive allele by "a," the genotype for a dominant individual would be written as "AA" rather than "aa."
When on e allele of a gene masks the presence of the other allele what form is masked?
The recessive allele.
What is a genetic factor that is blocked by the presence of a dominant factor?
A genetic factor that is blocked by the presence of a dominant factor is known as a recessive allele. In a heterozygous genotype, where one allele is dominant and the other is recessive, the dominant allele's traits will be expressed while the recessive allele's traits are masked. For example, in pea plants, the allele for tall stems (dominant) will override the allele for short stems (recessive), resulting in all offspring displaying the tall phenotype.
Can a sex-linked allele be dominant?
Yes, a sex-linked allele can be dominant. For example, if a gene on the X chromosome is dominant, females who inherit the allele will express the trait, while males only need one copy of the dominant allele to show the trait since they have only one X chromosome.

Allele that is always expressed if present?
An allele that is always expressed when it is present is the dominant allele.
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).
Is it proper to put the dominant allele before a recessive allele when determining the genotype?
Yes, it is common practice to denote the dominant allele before the recessive allele when writing a genotype to highlight the dominant trait. For example, if the dominant allele is represented by "A" and the recessive allele by "a," the genotype for a dominant individual would be written as "AA" rather than "aa."
If and individual has one dominant allele and one recessive allele will the recessive allele show up?
No, the dominant allele will be expressed in the individual's phenotype, masking the presence of the recessive allele. The recessive allele will only be expressed if an individual inherits two copies of the recessive allele.
What is the general term for an allele that masked in the phenotype by the present of another allele?
Recessive. It is denoted by the lower case version of the first letter of the Dominant gene. For example, if the dominant is "A" then the allele is "a".
Allele that prevents the expression of a recessive allele?
A dominant allele
What is an example of allele frequency?
An example of allele frequency is when in a population of 100 individuals, 60 individuals have the dominant allele (A) for a specific gene, while 40 individuals have the recessive allele (a). The frequency of the dominant allele (A) would be 0.6, and the frequency of the recessive allele (a) would be 0.4.
How do you write alleles?
Alleles are represented by letters, and two letters are used for each gene to denote the alleles inherited from each parent. For example, "Aa" represents a heterozygous individual with one dominant allele (A) and one recessive allele (a) for a particular trait. When writing alleles, uppercase letters are typically used to represent dominant alleles and lowercase letters are used for recessive alleles.
When on e allele of a gene masks the presence of the other allele what form is masked?
The recessive allele.
