What is 43 over 86 expressed in lowest terms?
43 over 86, when expressed in lowest terms, is 1 over 2.
What is the measure of the steepness of line expressed as rise over run?
The measure of the steepness of line expressed as rise over run is called slope.
What cannot be expressed in the form a over b?
An irrational number cannot be expressed in form of a/b.
What is 8 over 100 expressed as a decimal?
0.08
What is 1 over 6 expressed as a percentage?
16.6 repeating.
What is a reccesive gene?
an allele that is not expressed when paired with a dominant allele. Only expressed when paired with another recessive allele.
What is meant by dominat and ressesivegene give an exampleof each?
A dominant gene refers to a gene that is expressed over another gene in the same position on a chromosome. It will always show its trait in the individual's phenotype if it is present in their genotype. For example, if a person inherits a dominant gene for brown eyes, they will have brown eyes regardless of whether they also have a recessive gene for blue eyes. On the other hand, a recessive gene refers to a gene that is not expressed when there is a dominant gene present. It is only expressed in the phenotype when there are two copies of the recessive gene in the genotype. An example is the gene for blue eyes, which will only be expressed when an individual has two copies of the recessive gene and no dominant gene for brown eyes.
Why can a person have one copy of the CF allele and be perfectly normal?
CF is recessive, and as such, the gene for non-CF is dominant over this gene. The CF gene will only be expressed in the phenotype and as a characteristic if the person has two of the recessive alleles.
Several of the different globin genes are expressed in humans but at different times in development what mechanism could allow for this?
differential gene regulation over time
What is dominant and recessive?
These are terms used in a punnet square. Dominant is the Phenotype, or a gene that is predicted to be expressed in a heterozygous being- the offspring of two beings with different traits. Recessive is the Genotype, or a gene that is predicted to be hidden in the Deoxyribose Nucleic Acid, (DNA,) of a heterozygous being. Sometimes there is Codominance, where both genes are fully expressed, or incomplete dominance, where the genes are mixed, and are partially expressed.
What genes are recessive traits?
These traits are called dominant traits. They will overcome the recessive gene and the dominant trait will be expressed. A recessive gene needs two alleles present in its genotype to be expressed.
Why are recessive alleles not always expressed as the phenotype?
recessive alleles get masked to show the difference in a dominant gene and a recessive gene. the dominate genes masks the recessive genes to show that the dominate gene is more dominate or more likely to be the outcome than the reccessive gene but the masked gene is not always recessive.
Constituents of a gene?
There are three main parts of a gene. First, the promoter includes when and where the gene should be transcribed. Then, the coding sequence contains the instructions for making a protein. Last, the terminator indicates that the coding sequence is over.
What trait is expressed when two different genes for the same trait are present is called?
It depends which one is the dominant gene, and which is recessive. Dominant always over rules recessive. I probably spelled recessive wrong so yeah... :P
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.
When one gene expresses itself over another the former gene is called what?
The gene that expresses itself over the other is Dominant. The former gene is recessive.
What is 48 over 64 expressed as a percentage?
48 over 64 expressed as a percentage is 75%.
