The different forms of a genes for a single trait are known as alleles there can be a dominate allele which always shows up when present and a recessive allele which only shows up when both alleles are recessive or there is no dominate allele
The different forms of a gene are called alleles.
Different alleles for a trait are known as gene variants. For example, two different alleles for the gene that determines flower color in pea plants are purple (P) and white (p). When an individual has two different alleles for a trait, it is known as heterozygous.
A recessive gene will not display its trait in the presence of a dominant trait. A recessive gene only expresses its trait when paired with another copy of the same recessive gene.
A gene that shows no impact on a trait in a heterozygous state is called a recessive gene. In a heterozygous individual, the dominant gene will determine the trait expressed, while the recessive gene remains hidden.
It is a dominant trait. You only need one gene of a dominant trait for that trait to be expressed. You need two copies of the recessive trait in order for the trait to be expressed.

No, the frizzle trait in chickens is not an example of pleiotropy. Pleiotropy refers to a single gene affecting multiple traits. However, the frizzle trait is controlled by a single gene that affects only one observable trait - the curliness of feathers.
A living thing with a dominant and a recessive gene for a trait is heterozygous. This individual will display the dominant phenotype for that trait but may have offspring that display the recessive trait.
A gene can have multiple forms, which are called Alleles. While a single gene may code for a trait in an organism, when multiple alleles exist for that gene, each different may produce a different character of that trait. For example, a person has two copies of the gene that codes for ABO blood type. There are three different alleles for this gene, A, B and O. This results in six different combinations of the alleles that the person can have (the genotype), which in turn results in four expressions of the gene in the person (called the phenotype), which is the blood type of the person.
Allele is the term that describes the form of a gene that produces a specific trait such as long feathers or short feathers. Traits are passed in discrete units from parents to there offspring.

A gene that shows no impact on a trait in a heterozygous state is called a recessive gene. In a heterozygous individual, the dominant gene will determine the trait expressed, while the recessive gene remains hidden.
