What else can I help you with?
A single individual carries how many alleles for a trait?
It depends on the trait. Some traits are controlled by several alleles. Some traits are simply one of many controlled by a single allele. It also depends and how you correlate the trait with the allele. Sometimes a completely unrelated allele can "turn on" or "turn off" other sets of alleles. This means that the number of alleles associated with a particular trait can ultimately be indeterminable by our current observational methods.
What is an example of a human trait caused by a single gene with multiple alleles?
An example of a human trait caused by a single gene with multiple alleles is the ABO blood group system. This system is determined by the presence of different alleles at the ABO gene locus, specifically A, B, and O alleles. The combinations of these alleles result in four possible blood types: A, B, AB, and O, illustrating how multiple alleles can influence a single trait.
Organism that has two diffrent alleles for a single trait?
An organism that has two different alleles for a single trait is called heterozygous. This means that the organism inherited different versions of the gene responsible for that trait from each parent.
What is one difference between single gene trait and a polygenic trait?
Polygenic traits result in more variation because so many more alleles are involved in the process of reproduction.
Which describes the mating of organisms that have different homozygous alleles for a single trait?
When organisms with different homozygous alleles for a single trait mate, they produce offspring that are heterozygous for that trait. For example, if one parent has homozygous dominant alleles (AA) and the other has homozygous recessive alleles (aa), all offspring will be heterozygous (Aa). This can lead to the dominant trait being expressed in the offspring, while the recessive trait remains masked. The genetic variation introduced can significantly influence traits in future generations.
Can several alleles affect a single trait like eye color?
Alleles affect traits like eye color. Alleles for brown and blue eyes are dominant and recessive respectively. Individuals who have homozygous and heterozygous genotypes with the dominant allele will have brown eyes. However individuals are homozygous for the recessive allele will have blue eyes.
What are both inherited alleles called?
Genetic makeup formed from both inherited alleles together is called a genotype. Homozygous alleles would be a pair of identical alleles for a single trait. Heterozygous is different alleles for a single trait.
When more than two different alleles control a trait?
This phenomenon is known as multiple allelism, where there are more than two different variations of a gene (alleles) that can affect a single trait. In this case, individuals can inherit one of several possible alleles for the trait. Examples include the ABO blood group system in humans, where there are three alleles (IA, IB, i) that determine a person's blood type.
What is the difference between a single gene and a polygenics trait?
A polygenic trait is a trait in which multiple sets of alleles are used to determine the trait, whereas in a single gene trait aka. a Mendelian trait, only one pair of alleles is used.
DNA coding regions that affect the same trait are called?
alleles
When two or more sets of alleles affect the same trait in an additive fashion the trait is termed?
Yes, a single gene can affect many traits. this is called plieotropy
What is a gene trait?
A single-gene trait is a phenotypic trait controlled by two homologous alleles.
A single individual carries how many alleles for a trait?
It depends on the trait. Some traits are controlled by several alleles. Some traits are simply one of many controlled by a single allele. It also depends and how you correlate the trait with the allele. Sometimes a completely unrelated allele can "turn on" or "turn off" other sets of alleles. This means that the number of alleles associated with a particular trait can ultimately be indeterminable by our current observational methods.
What do geneticists call alleles that are both expressed in the phenotype when they are together?
Genetic makeup formed from both inherited alleles together is called a genotype. Homozygous alleles would be a pair of identical alleles for a single trait. Heterozygous is different alleles for a single trait.
