Your question: What is an example of how alleles and traits are related?

How do alleles genes and traits relate to each other?

A gene is a portion of DNA that determines a certain trait. An allele is a specific form of a gene. Genes are responsible for the expression of traits. Alleles are responsible for the variations in which a given trait can be expressed.

How do alleles relate to the trait you can see?

Alleles contribute to the organism’s phenotype, which is the outward appearance of the organism. Some alleles are dominant or recessive. When an organism is heterozygous at a specific locus and carries one dominant and one recessive allele, the organism will express the dominant phenotype.

How are alleles and traits related quizlet?

How do alleles determine the expression of traits? if the two alleles are dominant then the dominant trait will be expressed. if the two alleles are recessive then the recessive trait will be expressed.

How does an allele cause a trait in an organism?

Although an individual gene may code for a specific physical trait, that gene can exist in different forms, or alleles. One allele for every gene in an organism is inherited from each of that organism’s parents. … Alleles produce phenotypes (or physical versions of a trait) that are either dominant or recessive.

Whats an allele example?

The definition of alleles are pairs or series of genes on a chromosome that determine the hereditary characteristics. An example of an allele is the gene that determines hair color. … Any of the alternative forms of a gene or other homologous DNA sequence.

What is an example of a trait?

Trait is a specific characteristic of an individual. For example, their hair color or their blood type. Traits are determined by genes, and also they are determined by the interaction with the environment with genes. And remember that genes are the messages in our DNA that define individual characteristics.

How do you explain alleles to a child?

Allele – While the section of DNA is called a gene, a specific pattern in a gene is called an allele. For example, the gene would determine the hair color. The specific pattern of the hair color gene that causes the hair to be black would be the allele. Each child inherits two genes for each trait from their parents.

How are genes and alleles related to genotype and phenotype?

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.

Are traits alleles or genes?
