and figure it out, if you are desperate. Just keep in mind that the number of people in each country will affect the answer, so averaging will not work.
The way to calculate the frequency of blood types is to find the numbers of each allele in your gene pool and divide each number by the total number of alleles. Multiply the decimal by 100 and you have a percent- your allele frequency.
The frequencies of alleles A and B in a population can vary widely, as they depend on factors like genetic drift, mutation rates, and natural selection. Generally, allele frequencies are calculated as a proportion of the total number of alleles in a population. These frequencies can be influenced by various evolutionary mechanisms over time.

Is the three alleles of the single gene that controls blood type is said to be what alleles?
The three alleles of the single gene that controls blood type are typically referred to as A, B, and O. The A and B alleles are co-dominant to each other, while the O allele is recessive to both A and B.
What is the difinition of alleles?
An allele is a form of a gene. For example, the allele B may lead to black fur and the allele b may lead to white fur. Both B and b are alleles for fur colour.In general notation, dominant alleles are written with a capital letter (eg. B, T, P) and recessive alleles are written with a lower case letter (eg. b, t, p). A person will have two alleles (one from each parent) for every gene. Dominant alleles are expressed over recessive alleles.
Is ABO blood group determined by multiple alleles?
Yes, the ABO blood group system is determined by multiple alleles. There are three main alleles involved in the ABO blood group system: A, B, and O. These alleles determine the presence or absence of specific antigens on red blood cells, which results in the different blood types (A, B, AB, or O).
How does mutation occur in the population?
Mutation can create new alleles, therfore can change allele frequencies in a population.
How are alleles and genotypes related?
DNA is composed of long strings of nucleic acid sequences, but not all of them code for proteins. The ones that do are called genes. Alleles are different versions of a certain gene. For example, the gene that codes for blood type has 3 different alleles, A, B, and O. The genes that code for hair and eye color also have many different alleles.
What are 3 blood alleles?
Three common blood alleles are A, B, and O. A person's blood type is determined by the combination of these alleles. People with type A blood have A alleles, people with type B have B alleles, people with type AB have both A and B alleles, and people with type O have neither A nor B alleles.
What are all the possible combinations of alleles that each F1 parent can pass on to the offspring?
Each parent can pass on one of two alleles for each gene to their offspring. This results in four possible combinations: A-B, A-b, a-B, and a-b, where A and a represent alleles from one gene and B and b represent alleles from another gene.
Is the three alleles of the single gene that controls blood type is said to be what alleles?
The three alleles of the single gene that controls blood type are typically referred to as A, B, and O. The A and B alleles are co-dominant to each other, while the O allele is recessive to both A and B.
In a population the sum of the relative frequencies of all alleles for a particular trait is?
Gene or allele frequency
A trait has two alleles and their frequencies are represented by p and q. If p 0.42 what is q?
0.58
a trait has 2 alleles and there frequencies are represented by q and p if p = 0.90 what is q?
.9
Genetic drift can best be described as?
D) the change in frequencies of alleles due to random events
How are alleles frequencies related to gene pools?
The frequency of the allele represents the percentage of that allele in the gene pool
A trait has two alleles, and their frequencies are represented by p and q. If p = 0.68, what is q?
32 - apex
How do alleles influence natural selection?
It's the other way around: natural selection is the natural process that causes the frequencies of occurence of alleles in the population gene pool to shift.
What is the difinition of alleles?
An allele is a form of a gene. For example, the allele B may lead to black fur and the allele b may lead to white fur. Both B and b are alleles for fur colour.In general notation, dominant alleles are written with a capital letter (eg. B, T, P) and recessive alleles are written with a lower case letter (eg. b, t, p). A person will have two alleles (one from each parent) for every gene. Dominant alleles are expressed over recessive alleles.
How many alleles are there for blood type-?
There are three alleles for blood type: IA=Blood type A IB=Blood type B i=Blood type O The alleles for blood type A and B are codominant so when someone contains the IA and IB alleles, their blood type is AB.
