Albinism is a genetic condition caused by mutations in genes responsible for producing melanin, the pigment that gives color to skin, hair, and eyes. It is typically inherited as an autosomal recessive trait, meaning that an individual must inherit two copies of the recessive allele—one from each parent—to express the condition. If a person has only one copy of the recessive allele, they are considered a carrier but will not show symptoms of albinism. Thus, the presence of the recessive allele must be homozygous (two copies) for the phenotype of albinism to manifest.
What else can I help you with?
Is albinism controlled by a dominant allele o recessive allele?
It is controlled by a recessive allele.
Is albinism controlled by a dominant allele or by a recessive allele?
Recessive allele.
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?

Is albinism a dominat or reccesive trait?
Albinism is a recessive trait which will result in a lack of pigmentation in the skin eyes and hair. It occurs about 1 in every 17,000 people in the U.S.
Is straight hair controlled by a dominate allele or recessive allele?
Straight hair is typically controlled by a dominant allele. Curly hair is usually controlled by a recessive allele.
Two parents with normal pigmentation give birth to a child with albinism albinism is not a what?
Albinism is not a dominant trait; it is a recessive genetic condition caused by mutations in genes responsible for melanin production. Both parents can be carriers of the recessive allele for albinism, meaning they have normal pigmentation but can pass the allele to their child, resulting in the child having albinism.
What carrier of a trait controlled by a allele does not express the trait?
A carrier of a trait controlled by a recessive allele possesses one copy of the recessive allele and one copy of the dominant allele. This means that they do not express the trait associated with the recessive allele because the dominant allele masks its effect. However, the carrier can pass the recessive allele to their offspring, who may express the trait if they inherit two copies of the recessive allele.
Is albinism a recessive trait or dominant?
Recessive. The trait will only show up if both parents have the gene recessively (aa). If the genetic make up is Aa or AA, there will be melanin production, meaning albinism is an aa gene only. Albinism is a recessive allele.
Albinism is a recessive trait what is the only genotype that would express albinism?
Albinism is expressed only in individuals with the homozygous recessive genotype, represented as "aa." This means that both alleles for the trait must be the recessive form for the characteristic to manifest. Individuals with at least one dominant allele ("AA" or "Aa") will not express albinism.
What combination of alleles could produce a trait controlled by a recessive allele?
recessive + recessive or tt
When will a trait controlled by a recessive allele be shown?
only when two recessive alleles are present
Is albinism a dominant or recessive trait?
Albinism is a recessive trait.
