How do alleles make it possible for humans to have four different traits for blood type?
In human beings blood group is determined by four alleles IA, IB, Ii A gene contain only two alleles either IA IA-- result A group IA IB--- result AB group- because of the phenomenon of co-dominance IA Ii---- result A group- A is dominant over i IBIi--- result B group- B is dominant over i IB IB-- result B group Ii Ii-- result O group dr.sreejithnamboodiri@gmaill.com
What else can I help you with?
In ------ these are more than two alleles possible for a trait?
In multiple-allele inheritance, there are more than two alleles possible for a trait. This means that instead of just two versions of a gene (alleles), there can be multiple variations that influence the trait in different ways. Examples of traits with multiple alleles include blood type in humans and coat color in rabbits.
Do humans have the same combination of alleles?
No, humans do not have the same combination of alleles. Alleles are different versions of a gene that can vary between individuals, leading to genetic diversity within the human population. This diversity is what accounts for the differences in traits and characteristics among individuals.
In what way are alleles and traits related?
Alleles are different forms of a gene that can determine specific traits in an organism. Traits are characteristics or features that are influenced by the alleles present in an individual's genetic makeup. In other words, alleles and traits are related because alleles determine the traits that an organism will exhibit.
What organisms is heterzygous?
A heterozygous organism has two different alleles for a given gene. The opposite of a heterozygous organism is a homozygous organism which has two alleles that are the same for that specific gene. Genes can exist in more than one form and the different forms are called alleles. Alleles code for different types of the same characteristic
Are alleles different versions of the same gene?
Yes, alleles are different versions of the same gene that can result in variations in traits.
What allows humans to have different traits?
Different alleles allow people to have different traits from each other.
What will a population with different alleles have?
A population with different alleles will have traits
How does the range of phenotypes for single gene traits different from the range for polygenic traits?
ABO Single gene trait blood group alleles on humans. That is the variation, not much, and not much recombination. 3! = 6. There is posited to be at least 7 alleles for height, which is a polygenic trait. Hypothetical alleles, SMYDKECV 7! = 5040 different combinations of alleles in height polygenic traits.

No, humans do not have the same combination of alleles. Alleles are different versions of a gene that can vary between individuals, leading to genetic diversity within the human population. This diversity is what accounts for the differences in traits and characteristics among individuals.
What causes a wide range of phenotypes for some traits?
Some traits, such as eye color and hair color, have multiple alleles that control different aspects of the phenotype. Because there are multiple different possible combinations of alleles, you get a wide range of phenotypes.
In what way are alleles and traits related?
Alleles are different forms of a gene that can determine specific traits in an organism. Traits are characteristics or features that are influenced by the alleles present in an individual's genetic makeup. In other words, alleles and traits are related because alleles determine the traits that an organism will exhibit.
Do humans have alleles?
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 name for different forms of traits?
alleles
Why do population have variations in certain traits?
For one thing, different individuals have different alleles.
Blood types in humans are an example of traits controlled by?
Multiple alleles
What traits are controled by a gene with multiple alleles?
Traits controlled by a gene with multiple alleles can vary in terms of expression or phenotype. For example, human blood type (A, B, AB, O) is controlled by a gene with multiple alleles. The different alleles can result in different phenotypes (A, B, AB, O) for the same trait.
