What does the notation AA means to genetics?
In genetics, the notation AA represents a genotype where both alleles at a particular gene locus are the same and are dominant. This means that both copies of the gene are identical and code for the same trait.
Are cats curly ears a dominant and recessive trait?
Curling ears in cats can be caused by a genetic mutation that is a dominant trait. When a cat inherits the gene for curled ears from one parent, it will display the trait. Curled ears are not a recessive trait because even when present with a normal ear gene, the curled ear gene will dominate and be expressed in the cat's appearance.
What percentage of the offspring will most likely show the dominant trait?
More information is needed. The percent of offspring that will display the recessive trait from parents with Hh and HH will be different than the percent of offspring that will display the recessive trait from parents with hh and Hh.
How are single-gene traits useful in studying human genetics?
It's useful because you can find out if a trait is dominate or recessive easily. If a trait requires multi genes, its much harder to find out if that trait is recessive or dominate, and also if there are other inhibitors that may effect the gene as well.
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
When will 2 dominate trait show its affect?
In the presence of one dominate gene
What does the notation AA means to genetics?

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.
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.
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.

How do you get brown eyes from blue eyed parents?
if you go back to the beginning of your family tree, maybe a family member had brown eyes brown eyes is a dominate trait and blue eyes is a recessive trait, even tho they may both show the recessive trait they may both poses the brown eyes dominate trait and pass it onto you and you will show it. as the name implies you are more likely to show the dominate trait (75% chance dominate and 255 chance recessive). interestingly enough this means that you do have the recessive blue eye trait but you do not show it.
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.
Why is it possible that a majority of people may display a recessive trait?
It is possible for many people to display a recessive trait because the people have two recessive genes. Dominant simply means it will trump a recessive gene, it does not mean it is the most widely seen gene in a species.
A genetic trait expressed in a person who has only one copy of the gene associated with the trait?
This is known as a dominant trait. Dominant traits require only one copy of the gene to be expressed in an individual. The presence of one dominant allele is sufficient to display the trait, even if the individual also carries a different allele for the same gene.
If a baby goat received dominant gene for curly hair from one parent and recessive gene for straight hair from the other which trait will the baby goat display?
curly hair, as the dominant gene overrules the recessive gene I THINK :)
