Why does the baby have only two alleles if the inheritance of blood type is controlled by three alleles?
Blood type inheritance is determined by three alleles (A, B, O), but an individual inherits only two alleles, one from each parent. This means a baby can have only two alleles for blood type, such as AO or BO, even though three alleles exist in the population.
The number of alleles of a certain type divided by the total number of alleles is what?
Alleles Frequency
Multiple alleles can be studied only in individuals?
Multiple alleles can indeed be studied in individuals, particularly through genetic analysis to determine which alleles are present in a given locus. This involves examining the different forms of a gene that can exist in a population, known as alleles, and how they interact to produce a specific trait or characteristic in an individual. This can provide insights into genetic diversity and inheritance patterns within a population.
What type of alleles are expressed only if two identical copies exist on the homolgs of the offspring?
Recessive because...
What type of alleles mask recessive alleles?
Dominant 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).
What type of alleles does a plant have?
unlike 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.
What are multiple allels in biology?
Multiple alleles is a type of heredity in which one gene has more than two alleles. For example, in humans the gene for blood group has three alleles, A, B, and O. Even though there are three alleles in the population, a person can only inherit two alleles, one from his/her mother and one from his/her father.
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 is the difference between codominance and multiple alleles?
Codominance occurs when both alleles in a heterozygous individual are fully expressed, resulting in a phenotype that displays characteristics of both alleles, such as in blood type AB. Multiple alleles refer to the existence of more than two alternative forms of a gene within a population, allowing for a variety of genotypes and phenotypes, like the ABO blood group system where three alleles (A, B, O) determine blood type. While codominance describes the expression of alleles, multiple alleles describe the variety of alleles available for a trait.
Blood type in humans is controlled by which alleles?
Human blood type is determined by codominant alleles.
