Which trait will be expressed if both dominant gene and recessive gene are in the gene pair?

The current school of thought is that a dominant gene needs only a single copy to express its coding where as a recessive gene needs two copies of itself. The different forms of a gene are called alleles. Each parent contributes an allele. For example brown eyes and blue eyes. A blue eyed person would have two blue eye genes. A brown eyed person would have at least one brown eyed gene and either a blue or brown eyed companion. Hence two blue eyed people should only have blue eyed children. Two brown eyed people could possibly have either blue or brown eyed children.
Science is discovering that genes interact in very complex ways. There is dominance, recessive, codominance, corecessive, and interactions between multiple genes to produce an outcome. While the reporting of DNA research and discoveries may make it seem we have an understanding of how genes work the reality is that the study of DNA and its functions is still in its infancy.

∙ 12y agoIn simple dominate and recessive genetics if the person inherits two copies of the recessive form of a gene then they will display the recessive phenotype. If the person receives two copies of the dominate gene then the person will display the dominate phenotype.
However, if the person receives one copy of the recessive and one copy of the dominate gene then the person will display the phenotype of the dominate form of the gene.

Is heterozygeous dominant or reccesive?
Heterozygous means that it carries both dominant and recessive traits (as opposed to homozygous which carries only one) - the dominant trait is the one which is expressed (phenotype). A heterozygous trait can be expressed as Rr - "R" the dominant trait and "r" the recessive trait.
What is a trait that needs two factors in order to be expressed?
Actually, it is the recessive.................................................................UR WELCOME! :)
Comapre and contrast dominant and recessive traits?
Dominant traits only require one allele to be present in order for the trait to be expressed, while recessive traits must have both alleles present in order for the trait to be expressed.
What is the only way a recessive trait will be expressed?
Breed/use only organisms showing the recessive trait for starters. If one of the parents or progenitor lines show the dominant trait then don't use their offspring. If the offspring of one of the oranisims show the dominant trait then remove both the parent of this offspring and this offspring showing the dominant trait from your program.
If an offspring receives a pair of trait-controllers containing both a dominant and a recessive trait what happens to the recessive trait?
The dominant trait is shown in that organism with the possibility of carrying either the dominant or recessive gene to the next generation
Which form of gene pair is expressed when both dominant and recessive are present?
If the gene is governed by a dominant and recessive allele, then if the dominant allele is present, the dominant trait will be expressed. If both alleles are recessive, then the recessive trait will be expressed.
When neither allele is dominant (they are both expressed)?
Both of the alleles must be recessive. The trait expressed is a recessive trait.
When neither allele is dominant what are they expressed as?
Both of the alleles must be recessive. The trait expressed is a recessive trait.
What is difference between a dominant trait and a recessive trait?
A recessive trait is a trait that is not shown or expressed physically but is retained within the persons genes, whereas a dominant trait is a trait which opresses the recessive trait and is prodominantly shown or expressed physically. For example it is possible for two red-haired parents, both with recessive dark haired genes, to have a dark haired child. they must both have the recessive gene or the dominant gene of red - hair will be expressed in the child
Is heterozygeous dominant or reccesive?
Heterozygous means that it carries both dominant and recessive traits (as opposed to homozygous which carries only one) - the dominant trait is the one which is expressed (phenotype). A heterozygous trait can be expressed as Rr - "R" the dominant trait and "r" the recessive trait.
What is it called having a dominate and recessive allele?
If an individual has one recessive allele and one dominant allele, they are known as heterozygous. The dominant trait will be expressed.
Is a recessive gene expressed?
Ok, im assuming your question is "if two recessive alleles are present will the trait be expressed" A trait will be expressed if two alleles are recessive but it will not be the same representation as two dominant alleles. For example, T being a tall pea plant and t being a small pea plant. Two recessive alleles or, homozygous recessive, alleles The other option would be there is one dominant and one recessive, heterozygous, which would look like Tt. This would take on the trait of the dominant allele usually expressed by the capital letter. So this heterozygous plant would be tall.

What is meant by dominance and recessiveness?
First of all alleles code for different traits all across an organism. Simply looking at it, a dominant allele is a trait that essentially "dominates" or is expressed over a recessive allele. In theory every organism (that is not asexual) receives one allele from its father and one allele from its mother. If both of these alleles are dominant (homozygous dominant) than the dominant trait is expressed, if one is dominant and one is recessive (heterozygous) than still the dominant trait is expressed. However, if the alleles for both traits are recessive (homozygous recessive) than the recessive trait will be expressed.
Comapre and contrast dominant and recessive traits?
Dominant traits only require one allele to be present in order for the trait to be expressed, while recessive traits must have both alleles present in order for the trait to be expressed.
In which offspring does a dominant trait appear?
if a trait is recessive, it can only be expressed if its other trait is recessive as well. If the other trait in the genotype is dominant, it will block the recessive factor. But if both are recessive, they will be able to be seen in the offspring.
What is the only way a recessive trait will be expressed?
Breed/use only organisms showing the recessive trait for starters. If one of the parents or progenitor lines show the dominant trait then don't use their offspring. If the offspring of one of the oranisims show the dominant trait then remove both the parent of this offspring and this offspring showing the dominant trait from your program.
