Is albinism controlled by a dominant allele or by a recessive allele?
Recessive allele.
Is albinism controlled by a dominant allele o recessive allele?
It is controlled by a 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?

What is an example of allele frequency?
An example of allele frequency is when in a population of 100 individuals, 60 individuals have the dominant allele (A) for a specific gene, while 40 individuals have the recessive allele (a). The frequency of the dominant allele (A) would be 0.6, and the frequency of the recessive allele (a) would be 0.4.
How can albinism in plants keep occurring if they cannot reproduce?
because the recessive allele is still present in heterozygous individuals. these individuals have one dominant allele and so show the dominant phenotype but they are capable of producing offspring with the recessive condition
What is a fixed allele.?
An allele present in all members of a population
What is allele fixation?
An allele present in all members of a population
A moth has two alleles for spots. It can have brown and white spots. The white spot allele frequency is 0.53. What is the brown spot allele frequency?
The total frequency of alleles in a population must equal 1. If the frequency of the white spot allele is 0.53, then the frequency of the brown spot allele can be calculated by subtracting the white allele frequency from 1. Therefore, the frequency of the brown spot allele is 1 - 0.53 = 0.47.
If an allele makes up one half of the frequency of a populations allele for a given trait it's allele frequency is?
its not anything.
The change in allele frequency?
Random change in allele frequency is called genetic drift.
Could you define Minor and major allele frequency?
Minor allele frequency (MAF) is the frequency at which the less common allele appears in a particular population. Major allele frequency (MAF) is the frequency at which the more common allele appears in a particular population. They are useful measures for studying genetic variation within populations.
How is albinism controlled by a recessive allele?
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.
