A piece of DNA which controls a trait is a gene variations of a gene are called alleles. If you mean "controls how much a particular trait is expressed" then you would be dealiung with the promoter region of a gene which is near the start and controls how strongly a gene is expressed.

How many genes minimum is needed to determine a trait?
The least number is 2, however this is very rare. Most traits require many genes to produce a trait.
What is a trait or genetic disorder caused by Polygenic inheritance?
A polygenic trait is a trait which multiple genes affect. An example would be skin color, the combined affects of several genes determine your base pigment shade. Polygenic traits are caused by a combination of genes.
What kind of trait is present when many different genes different genes control a single trait such as skin color?
epistasis
What is used to describe a trait that is controlled by many genes?
A genetic trait.
What is the characteristic caused by genes?
trait
What is the number of genes that usually determines a trait?
the number of genes that usually determine a trait
A typical gene contains the instructions for making?
It depends. Some genes determine a single trait all by themselves. Some genes work with other genes to make a trait. It takes several separate genes to determine how tall you will be. And then there are other genes that by themselves determine multiple traits. Each gene is the code for a peptide chain. Many of those become proteins.
What do you call one set of instuctions for an inherited trait?
genes
How many genes minimum is needed to determine a trait?
The least number is 2, however this is very rare. Most traits require many genes to produce a trait.
How many genes determine an inherited trait?
Hello there! Traits controlled by two or more genes are for example skin color and height.
One set of instructions for an inherited trait?
They are called alleles.
What is more than one set of genes controls a trait?
genetic traits
What is it when more than one set of genes controls a trait?
It is called polygenic inheritance.
What is the difference between a gene and trait?
Trait is a characteristic like: tall, short, black eyes, blue eyes Trait is determine by the genes: your gene is a little section on chromosome. A gene that control 1 trait usually have 2 alleles, for ex: Blue eyes is : Bb (b or B are the alleles make up the gene that determine the trait.) hope this help for whoever confuse!
What trait is is expressed when two diffrent genes for the same trait are present?
A dominant trait is expressed when two different genes for the same trait are present.
What is one set of instructions for an inherited trait?
The gametes (sex cells) that combine to form a new organism in sexual reproduction each contain one set of the instructions for the genes of the new organism, that is, one set each for each trait.
What is a trait or genetic disorder caused by Polygenic inheritance?
A polygenic trait is a trait which multiple genes affect. An example would be skin color, the combined affects of several genes determine your base pigment shade. Polygenic traits are caused by a combination of genes.
