What is e difference between a dominate and recessive allele?
The answer is that The difference is that dominant dominates, and recessive is dominated.
What is the allele which is overuled?
The two types of alleles are dominant and recessive. The recessive allele will still be present but the recessive trait is not usually seen. However, is not always overruled. In the cases of codominance and incomplete dominance, the recessive trait still shows through some of the dominant one.
Does a dominant allele mask a ressessive allele?
In diploid organisms (those with two copies of each gene carried on separate chromosomes), one of the copies of a given gene may differ from the other copy of the same gene on the twin chromosome. In some cases one version of the gene (the dominant allele) has the effect of 'masking' the activity of the other (the recessive allele); that is, the presence of the dominant allele negates the effect of the recessive allele on the organism's phenotype. There are many mechanisms which can cause this phenomena, and it depends on the particular genes involved, but a simple model is one where the recessive allele is a biochemically inactive version of the dominant allele. In this case the dominant allele would mask the effect of the recessive allele by providing an active version of the gene. The dominant phenotype would be the one which shows the downstream effects of this activity, and the recessive phenotype one which shows the downstream effects of a lack of activity. The dominant allele is said to 'mask' the recessive allele because only one copy is required to result in an elimination of the recessive phenotype, whereas all copies of the gene must be the recessive allele to result in the recessive phenotype.
What is the result when a dominant allele pairs up with a recessive allele in a simple dominance?
The dominant form of the trait shows. -Gradpoint
What the different between a dominant and recessive trait?
In simple Mendelian genetics, there may be several alleles (variations) for a given trait. since organisms generally have two pairs of chromosomes, they have two alleles. A dominant allele is one that when it is present, always shows itself. A recessive allele only shows when there are two copies of the recessive allele. For example, suppose brown hair is dominant and black hair is recessive. If there are any copies of the brown hair allele, the person's hair will be brown. A person's hair will be black only if they have two copies of the black hair allele. In reality, genetics is much more complicated than simply dominant and recessive as many genes may influence one trait.

What allele whose trait only shows up when no dominant allele is present?
Such a trait is called a recessive trait.

Why a plant with yellow pods can never be a hybrid?
Yellow pods are a recessive trait and for this type of trait to show in the phenotype, both alleles have to be recessive. If there was a recessive allele (yellow) and a dominant allele(green) as it shows in hybrid pods, then the dominant allele would be the one shown and the pod would be green.
Why is it that a person with an allele for a particular trait may not have a phenotype that shows the trait?
a dominant allele will express its trait , as well as be carried by the person. the word carrier is commonly used for a person who bears an allele which does not express itself(i.e. a recessive gene).

When is a recessive allel expressed in offspring?
A recessive phenotype is expressed in an offspring that has a homozygous recessive genotype for that trait.

What is a genotype with one dominant and one recessive gene?
The genotype of a person with one dominate allele for a gene and one recessive would be expressed as Aa or Yy. You can use any letter you would like except one will be shown as a capital (dominate) and one as a lower case (recessive). This combination is heterozygous for that trait.
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
