A dominant gene is always expressed if present, and the recessive gene is only expressed with the homozygous recessive genotype. For example, if the dominant gene is red (represented by the letter R) and the recessive gene is white (represented by the letter r), then a homozygous dominant organism's genotype will be RR, and its phenotype will be red. If the organism is homozygous recessive, then the genotype will be rr and the phenotype will be white. If the organism is heterozygous, then the genotype will be Rr, and the organism will be red.
What else can I help you with?
What gene will exhibit its traits even in a prensesce of a recessive gene?
A dominant gene will exhibit its traits even in the presence of a recessive gene. This is because the dominant gene masks the expression of the recessive gene when present in the same individual.
How many copies of a recessive gene does it take to overpower a dominant gene?
It takes two copies of a recessive gene to overpower a dominant gene. This is because a dominant gene will be expressed over a recessive gene in individuals who carry one copy of each type.
A gene is recessive when?
Most genes have two copies of each gene with dominant gene "trumping" the recessive one. The gene is recessive because it is said not to do much of anything unless paired with another recessive gene, but if paired with a dominant gene, the dominant gene wins.
Can a recessive gene be hidden from a dominant?
The dominant gene will always "cover up" the recessive gene, although there are instances of codominance, in which both phenotypes will be displayed, because one gene is not completely dominant over the other. There is also what is called 'incomplete dominance', when the actual phenotype is somewhere between the two.
When one gene expresses itself over another the former gene is said to be the DNA?
The gene that expresses itself over the other is Dominant. The former gene is recessive.
What is an organism that has a dominant and a recessive copy of a gene?
dogs have a dominant and a recessive copy of a gene
What gene will exhibit its traits even in a prensesce of a recessive gene?
A dominant gene will exhibit its traits even in the presence of a recessive gene. This is because the dominant gene masks the expression of the recessive gene when present in the same individual.
Is a situation in which a dominant allele completely masks a recessive allele for a gene.?
If you have 2 dominant alleles, the gene will be dominant, if you have 2 recessive alleles, the gene will be recessive. But if you have 1 recessive and 1 dominant, the Dominant allele will mask the recessive one.
How many copies of a recessive gene does it take to overpower a dominant gene?
It takes two copies of a recessive gene to overpower a dominant gene. This is because a dominant gene will be expressed over a recessive gene in individuals who carry one copy of each type.
Genes that are only seen when paired with a recessive gene?
Recessive genes are only expressed when an individual has two copies of the recessive allele. If an individual inherits one dominant allele and one recessive allele for a particular gene, the dominant allele will be expressed phenotypically. The recessive allele will only be expressed if the individual inherits two copies of the recessive allele.
A gene is recessive when?
Most genes have two copies of each gene with dominant gene "trumping" the recessive one. The gene is recessive because it is said not to do much of anything unless paired with another recessive gene, but if paired with a dominant gene, the dominant gene wins.
Can two dominant genes equal a recessive gene?
No, two dominant genes cannot equal a recessive gene in terms of genetic expression. In a dominant-recessive gene relationship, the dominant gene will be expressed over the recessive gene.
Can a recissive gene be dominant?
No, a recessive gene cannot be dominant. In genetics, dominant genes are expressed over recessive genes when present in an individual's genotype. This means that if a gene is recessive, it will only be expressed if an individual inherits two copies of that specific recessive gene.
Can a recessive gene be hidden from a dominant?
The dominant gene will always "cover up" the recessive gene, although there are instances of codominance, in which both phenotypes will be displayed, because one gene is not completely dominant over the other. There is also what is called 'incomplete dominance', when the actual phenotype is somewhere between the two.
The weaker of two genes is called what?
The weaker of two genes is called the recessive gene. In the presence of a dominant gene, the recessive gene is not expressed in the organism's phenotype.
What gene won't display its trait in the prescience of a dominate trait?
A recessive gene will not display its trait in the presence of a dominant trait. A recessive gene only expresses its trait when paired with another copy of the same recessive gene.
When one gene expresses itself over another the former gene is said to be the DNA?
The gene that expresses itself over the other is Dominant. The former gene is recessive.
