What gene won't display its trait in the prescience of a dominate trait?

The recessive form of a gene, called a recessive allele, will not be expressed in the presence of the dominant form of the gene, called a dominant allele.

What does the notation AA means to genetics?
AA means that a trait is homozygous dominate. A person only has one variation of a gene (trait) and it is dominate.
How are single-gene traits useful in studying human genetics?
Single-gene traits are useful in studying human genetics because they exhibit a clear inheritance pattern, making it easier to trace their transmission through generations. This allows researchers to identify the specific gene responsible for the trait and study its function and impact on human health. Additionally, single-gene traits can provide insights into genetic disorders and help in developing targeted treatments or interventions.
WHAT is single gene trait?
A single-gene trait is a phenotypic trait controlled by two homologous alleles.
What is an example of a different form a gene may have for a trait?
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
What is strand of DNA that codes for a specific trait?
A gene is a strand of DNA that codes for a specific trait
When will 2 dominate trait show its affect?
In the presence of one dominate gene
A living thing with a dominant and recessive gene for a trait?
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.
What does the notation AA means to genetics?
AA means that a trait is homozygous dominate. A person only has one variation of a gene (trait) and it is dominate.
What is a dominate trait?
Dominant trait is a genetics term. A dominant trait is one which will be expressed if one of the parents has the gene for that trait. A recessive trait is one that will be expressed only if both parents carry the trait.
How do dominate traits over power the recessive?
dominates it (you get the dominant form)
How many alleles are usually in the gene pool for each trait?
Each gene has a dominate and recessive allele, so there are two types of alleles in each gene. The dominate allele is stronger than the recessive allele unless there are two recessive alleles.
What does it mean that an organism is homozygous recessive for a trait?
That organism has two recessive alleles for that trait, one from each parent. It will display the recessive trait.
What does being heterozygous for some genetic trait mean?
the 2 alleles of the gene for the trait are different on the 2 homologous chromosomesBeing heterozygous for a trait means that they have different alleles for a trait. For instance: Tt would be heterozygous and TT or tt would be homozygous because they are both eitehr little or big t's.it mean the gene is not pure or for example suppose a person is blood group A but actually he is having A and O; because O is recessive trait the gene express the A trait instead, making the person having blood group A.
How do you prove gene dominance?
When two heterozygous organisms are mated, approximately 75% of these organisms should display the trait if it is dominant. 25% would display the recessive gene. If these numbers are very far off, chances are the gene you were testing was not a dominant trait.
Why is it possible that a majority of people may display a recessive trait?
A recessive trait can be masked by a dominant trait in individuals who are heterozygous. Thus, a majority of people may appear to display the dominant trait even if they are carriers of the recessive trait. Only when two carriers of the recessive trait have children together is there a chance for the recessive trait to become visible in the offspring.
All of the offspring display only one form of a particular trait?
true breeding
