Would a dominant allele ever return to a population?
If a population does not have a particular dominant allele, it could return to the population through the immigration of new individuals carrying the dominant allele.
What is e difference between a dominate and recessive allele?
The answer is that The difference is that dominant dominates, and recessive is dominated.
What is the principle of allele specific oligonucleotide polymerase chain reaction?
The principle of allele-specific oligonucleotide polymerase chain reaction (ASO-PCR) involves designing primers that are specific to the target allele sequences. By using these specific primers, only the allele of interest is amplified during PCR, allowing for the detection and identification of specific alleles. ASO-PCR is commonly used to genotype individuals based on the presence or absence of specific genetic variations.
What factor determines whether the frequency of the new allele will increase?
Which factor might determine whether the frequency of the new allele will increase in a population where a mutation occurs?
A person can be tested for the allele that causes Tay-Sachs disease because the what of that allele is different from that of the normal allele?
The DNA sequence of the allele that causes Tay-Sachs disease is different from that of the normal allele. This difference in the DNA sequence allows for specific genetic tests to be conducted to identify the presence of the Tay-Sachs disease allele in individuals.
What is an example of allele frequency?
An example of allele frequency is when in a population of 100 individuals, 60 individuals have the dominant allele (A) for a specific gene, while 40 individuals have the recessive allele (a). The frequency of the dominant allele (A) would be 0.6, and the frequency of the recessive allele (a) would be 0.4.
Why is a dominant allele called dominant apex?
because it dominates the phenotype
What type of allele is masked when a dominant allele is present?
The recessive allele is masked when a dominant allele is present. Dominant alleles are expressed over recessive alleles in heterozygous individuals.
The allele for the sickle cell trait is what with the normal allele?
The allele for the sickle cell trait is codominant with the normal allele. This means that in individuals with both alleles present, both traits are expressed.
1 in drosophila the allele for normal length wings is dominant over the allele for vestigial wings In populations of 1000 individuals 360 show the recessive phenotype How many individuals would you?
160 homozygous dominant individuals and 480 heterozygous individuals
How does a monohybrid differ from a dihybrid with respect to allele pairs?
monohybrid is a cross between two heterozygous (Aa x Aa), they are usually controlled by different alleles of the same gene. A monohybrid cross compares only one trait. while Dihybrid is a cross between F1 offsprings of two individuals that differ in two traits. Dihybrid croos are often used to test for dominant and recessive genes in two separate characteristics.
True or False In heterozygous individuals only the recessive allele is expressed?
In heterozygous individuals, only the dominant allele is expressed. The recessive allele is present, but not expressed
What is the relationship between allele frequency and genotype frequency in a population?
The allele frequency in a population determines the genotype frequency. Allele frequency refers to how often a particular version of a gene appears in a population, while genotype frequency is the proportion of individuals with a specific genetic makeup. Changes in allele frequency can lead to changes in genotype frequency within a population over time.
The genetic disease blue sclera is determined by an autosomal dominant allele The eyes of individuals with this allele have bluish sclera These same individuals may also suffer from fragile bones an?
deafness
Would a dominant allele ever return to a population?
If a population does not have a particular dominant allele, it could return to the population through the immigration of new individuals carrying the dominant allele.
What is e difference between a dominate and recessive allele?
The answer is that The difference is that dominant dominates, and recessive is dominated.
What is a different between allele and gene?
an allele is a gene that is the cause of hereditary variation
