What are the two different alleles for a gene?
I think it is Dominant and recessive.
Do all versions of each gene always get expressed in an organism?
No, only dominant traits will be expressed.
What is A version of gene is called?
Particular Versions of Genes are called Alleles - one way they differ is that some alleles are termed to be dominant while others are termed to be recessive.
What is the factor that seems to disappear due to a dominant allele?
An allele is one particular form of a gene. A large population of living things typically have several different allele for any particular gene. For example, one important gene in humans determines blood type compatibility. That gene comes in 3 different alleles -- A, B, and O. Most plants and animals are diploid -- they have 2 of each gene, one inherited from each parent. For example, any one human has one of six possible genotypes for that gene: AA, BB, OO, AB, AO, BO. A recessive allele seems to disappear when paired with a dominant allele. If something has a dominant and recessive allele, the dominant will overshadow the recessive, but the recessive will still be there (just not showing). For example, the O allele is recessive when paired with the A allele, which is dominant, and so humans with the AO genotype as well as the AA genotype have "type A blood". Only humans with the OO genotype show "type O blood". According to the Wikipedia "allele" article, some people once thought that all genes had only one "normal" allele, which was both common and dominant, and all other versions of that gene (all other alleles) were rare and recessive. However, most genes have many different "normal" alleles, whose frequencies vary from one population to another. With some genes, the most common allele is recessive.
What is incomplete and codominance?
Codominant alleles will both be expressed in the phenotype. So for example in the human ABO blood type, A and B are codominant. This means that a person with the alleles AB will have the characteristics of both A and B (they will have both A and B antigens on their blood cells). Another example of codominance - if B codes for black fur and b codes for white fur, an individual with Bb would have black and white spots/splotches/etc. Incomplete dominance is different in that the phenotype is a mix of the two. So for example, if B codes for black fur and b codes for white fur an individual with Bb would have grey fur (a mix of black and white).
An organism that receives two versions of a dominant trait?
dominant
Are sperm and egg cells in humans Have either all dominant or all recessive versions of genes?
The sperm and egg sex cells (or gametes) have both recessive and dominant genes in them.
What are individual versions of genes called?
Alleles I believe it is actually a monohybrid.
What are the two different alleles for a gene?
I think it is Dominant and recessive.
Do all versions of each gene always get expressed in an organism?
No, only dominant traits will be expressed.
How are dominant and recessive genes related?
Dominate them. Recessive alleles do not show in your phenotype unless you have two of the same recessive allele. But if you inherit one dominant and one recessive, it is the dominant that always shows in your phenotype.
How are dominant and recessive genes?
If you are talking about traits, dominant traits and recessive traits both have alleles. Dominant traits are alleles that cover up the expression of other alleles. One dominant allele with one recessive allele makes a dominant trait. Two dominant alleles together also make a dominant trate. Recessive traits are alleles that are only expressed when there is no dominant trait to cover them up. Two recessive alleles make a recessive trait. Traits can be passed over to the next generation. Two alleles together make a genotype, which is the inherited combination of alleles. Alleles: different versions of the same gene. Heredity: determined by genes. Genes: piece of DNA that shows the cell how to make a protein it needs.

What was Gregor Mendel's hypothesis in the pea plant experiment?
"Alternative versions of genes account for variations in inherited characters." "For each character trait (ie: height, color, texture etc.) an organism inherits two genes, one from each parent." "If the two alleles differ, then one, the dominant allele, is fully expressed in the organism's appearance; the other, the recessive allele, has no noticeable effect on the organism's appearance." "The two genes for each character segregate during gamete production."
What is codominace mean?
Codominance is a relationship between two versions of a gene. Individuals receive one version of a gene, called an allele, from each parent. If the alleles are different, the dominant allele usually will be expressed, while the effect of the other allele, called recessive, is masked.
