Best answer: Is an allele a genotype or phenotype?


Is genotype A allele?

In a broad sense, the term “genotype” refers to the genetic makeup of an organism; in other words, it describes an organism’s complete set of genes. In a more narrow sense, the term can be used to refer to the alleles, or variant forms of a gene, that are carried by an organism.

Can an allele be expressed as a phenotype?

For any gene, a person may have the same two alleles, known as homozygous or two different ones, known as heterozygous. The genotype is the collection of alleles that determine characteristics and can be expressed as a phenotype .

How are alleles related to the genotype?

Each pair of alleles represents the genotype of a specific gene. Genotypes are described as homozygous if there are two identical alleles at a particular locus and as heterozygous if the two alleles differ. Alleles contribute to the organism’s phenotype, which is the outward appearance of the organism.

What is another name for genotype?

Are alleles and phenotypes the same thing?

Different forms of a gene are called alleles. … The alleles an individual has at a locus is called a genotype. The genotype of an organism is often expressed using letters. The visible expression of the genotype is called an organism’s phenotype.

Is a dominant allele always expressed in the phenotype?

Alleles that exhibit complete dominance will always be expressed in the the cell’s phenotype. … So the dominant allele is always expressed, but it can differ in penetrance and is therefore not always as clearly expressed in the cell’s phenotype as you expect from a dominant allele.

Are both alleles expressed?

In most cases, both alleles are transcribed; this is known as bi-allelic expression (left). However, a minority of genes show monoallelic expression (right). In these cases, only one allele of a gene is expressed (right).

What is genotypic and phenotypic?

The genotype refers to the genetic material passed between generations, and the phenotype is observable characteristics or traits of an organism.

What is an example of a phenotype?

Examples of phenotypes include height, wing length, and hair color. Phenotypes also include observable characteristics that can be measured in the laboratory, such as levels of hormones or blood cells.
