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.
What else can I help you with?
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 type of study would a psychologist conduct to determine how much of a trait is influenced by genetics?
A psychologist would conduct a twin study to determine the heritability of a trait. By comparing the similarities between identical twins (who share 100% of their genes) with fraternal twins (who share 50% of their genes), researchers can estimate the genetic contribution to the trait.
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
What do you call one set of instuctions for an inherited trait?
genes
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.
Each hereditary trait corresponds to what?
Each hereditary trait corresponds to a specific gene or set of genes that encode the information for that trait. Genes are segments of DNA that determine specific characteristics, such as eye color or height. These genes are inherited from our parents and are responsible for the variation we see in physical attributes and other traits among individuals.
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?
An inherited trait is typically determined by multiple genes working together. The exact number of genes involved can vary depending on the trait. In many cases, dozens to hundreds of genes may contribute to a single inherited trait.
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 type of study would a psychologist conduct to determine how much of a trait is influenced by genetics?
A psychologist would conduct a twin study to determine the heritability of a trait. By comparing the similarities between identical twins (who share 100% of their genes) with fraternal twins (who share 50% of their genes), researchers can estimate the genetic contribution to the trait.
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 are the pair of alleles for a trait and how do they determine the expression of that trait?
Alleles are pairs of genes that determine a specific trait in an organism. Each parent contributes one allele, and the combination of alleles determines how the trait is expressed. If the alleles are the same (homozygous), the trait will be expressed in a certain way. If the alleles are different (heterozygous), one allele may be dominant and determine the trait's expression, while the other may be recessive and not expressed.
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.
