What trait is expressed when two different genes for the same trait are present is called?
This is called co-dominance - when both genes are expressed and visible in the phenotype.
A trait which results from two dominant genes is called?
A trait resulting from two dominant genes is called codominance. This means that both genes are expressed in the offspring, leading to a phenotypic trait that displays characteristics of both dominant alleles.
Can 4 recessive genes make a dominant gene?
No, the presence of 4 recessive genes cannot result in a dominant gene. Dominant genes are expressed when at least one copy of the dominant allele is present, masking the effects of any recessive alleles.
What gene is always expressed?
Dominant genes will always be expressed however recessive genes would need to be inherited from both parents
The dominant or recessive form that a gene takes is?
determined by its specific genetic instructions. Genes can be dominant (expressed when present) or recessive (expressed only when two copies are present) based on the interaction of alleles at a specific locus on a chromosome. The dominant form masks the recessive form in heterozygous individuals.
Which genes are dominant and which are recessive?
Dominant genes are always expressed in preference to recessive genes in cased where both genes are present.
Genes that prevent the other gene from showing traits are called?
Dominant genes. Dominant genes are always expressed in an organism's phenotype when present, masking the expression of recessive genes.
What genes are expressed even when present on only one chromosome?
dominant genes
Why are some genes are called dominant?
cause they can fool bi**
What trait is is expressed when two diffrent genes for the same trait are present?
A dominant trait is expressed when two different genes for the same trait are present.
What trait is expressed when two different genes for the same trait are present?
dominant
What are the difference between dominant and recessive genes?
Dominant genes are always expressed in the phenotype, even if there is only one copy present. Recessive genes are only expressed if both copies are present. Dominant genes tend to mask the effects of recessive genes in the phenotype.
What trait is expressed when two different genes for the same trait are present is called?
This is called co-dominance - when both genes are expressed and visible in the phenotype.
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.
A trait which results from two dominant genes is called?
A trait resulting from two dominant genes is called codominance. This means that both genes are expressed in the offspring, leading to a phenotypic trait that displays characteristics of both dominant alleles.
What is it called when both dominant and recessive genes are present?
Heterozygous, I believe.
Can 4 recessive genes make a dominant gene?
No, the presence of 4 recessive genes cannot result in a dominant gene. Dominant genes are expressed when at least one copy of the dominant allele is present, masking the effects of any recessive alleles.
