Albinism is a recessive trait in humans that is controlled by a single gene how many recessive alleles must a person have to have albinism?

Blood type in humans is determined by a single gene that has multiple alleles?
Each person has two alleles for their blood type, one dominant and one recessive. Except for type AB blood where the alleles are co-dominant. The allele for O blood is always recessive when paired with either an A or B allele.
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.
Blood type in humans is controlled by how many alleles?
Blood type in humans is controlled by three alleles at the ABO gene locus on chromosome 9. These three alleles are responsible for determining the blood types A, B, AB, and O. Each person inherits one allele from each parent, resulting in various blood type combinations.
Can several alleles affect a single trait like eye color?
Alleles affect traits like eye color. Alleles for brown and blue eyes are dominant and recessive respectively. Individuals who have homozygous and heterozygous genotypes with the dominant allele will have brown eyes. However individuals are homozygous for the recessive allele will have blue eyes.
In humans having wet earwax is a dominant trait. Having dry earwax is recessive. a) A man has two recessive alleles. What is his phenotype?
A man with two recessive alleles for earwax would have the phenotype of dry earwax. Since dry earwax is the recessive trait, having two recessive alleles means he expresses this trait. Therefore, his phenotype is characterized by dry earwax.
Albinism is a recessive trait in humans that is controlled by a single gene how many recessive alleles must a person have to have albinism?

What trait is controlled by a gene with multi alleles?
The ABO blood groups in humans are controlled by multiple alleles.
What is the blood type in humans controlled by?
Blood types are controlled by multiple alleles.
Recessive allele is more common or dominant allele?
Not necessarily. I think the dominant genes are more common, but there are lot of exceptions out there. For example, having six fingers in humans is a dominant gene, but it isn't all that common.
Blood type in humans is controlled by which alleles?
Human blood type is determined by codominant alleles.
In humans the alleles for hemophilia h is recessive. Which phenotype is displayed in an individual with the genotype XhY?
Genes that come together with different alleles are called _____.
Blood types in humans are an example of traits controlled by?
Multiple alleles
Blood type in humans is determined by a single gene that has multiple alleles?
Each person has two alleles for their blood type, one dominant and one recessive. Except for type AB blood where the alleles are co-dominant. The allele for O blood is always recessive when paired with either an A or B allele.
What are the two different alleles for a gene?
I think it is Dominant and recessive.
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.
What is it called when one trait is controlled by 4 alleles?
When one trait is controlled by four alleles, it is referred to as multiple allelism. In this genetic scenario, more than two alleles exist for a single gene within a population, leading to a variety of possible phenotypes depending on the combination of alleles present in an individual. An example of this is the ABO blood group system in humans, where four alleles (IA, IB, i) determine blood type.
