20 out of 100 rabbits have white fur what is the allele frequency for the recessive allele?
To find the allele frequency for the recessive allele, we first determine the proportion of rabbits with white fur, which is 20 out of 100, or 0.20. Assuming white fur is caused by a recessive allele (let's call it "a"), these rabbits represent the homozygous recessive genotype (aa). Using the Hardy-Weinberg principle, if q² = 0.20, then q (the frequency of the recessive allele) is the square root of 0.20, which is approximately 0.447. Thus, the allele frequency for the recessive allele is about 0.447 or 44.7%.
What else can I help you with?
In a certain population of rabbits the allele for brown fur is dominant over the allele for white fur. If 20 out of 100 rabbits have white fur what is the allele frequency for the recessive allele?
In this population, 20 out of 100 rabbits have white fur, indicating they are homozygous recessive (bb). The frequency of the recessive genotype (bb) is 0.20. Using the Hardy-Weinberg principle (p² + 2pq + q² = 1), we know q² = 0.20, so q (the frequency of the recessive allele) is the square root of 0.20, which is approximately 0.447. Thus, the allele frequency for the recessive allele is about 0.447.
In a certain population of rabbits the allele for brown fur is dominant over the allele for white fur. If 10 out of 100 rabbits have white fur what is the allele frequency for the dominant allele?
In the population of 100 rabbits, 10 have white fur, indicating that they are homozygous recessive (aa). This means that the frequency of the recessive allele (a) can be calculated using the formula ( q^2 = \frac{10}{100} = 0.1 ), so ( q = \sqrt{0.1} \approx 0.316 ). The frequency of the dominant allele (A) is then ( p = 1 - q \approx 1 - 0.316 = 0.684 ). Thus, the allele frequency for the dominant allele is approximately 0.684.
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.
What does this tell you about the allele for white hair in horses?
The allele for white hair in horses is present in this individual, as evidenced by the white hair present. This individual likely carries two copies of the allele, as white coat color is typically a recessive trait in horses.
What is the difference between dominant alleles and recessive alleles?
dominant-appears in first generation recessive-seems to dissapear

A population consists of 9 percent white sheep and 91 percent black sheep what is the frequency of the black wool allele if the black wool allele is dominant and the white wool allele is recessive?
If you assume hardy-weinburg equilibrium, then:let B = frequency of black allele (dominant)b = frequency of white allele (recessive)BB (or B^2) = frequency of homozygous black sheep2Bb = frequency of heterozygous black sheepbb (or b^2) = frequency of white sheepSince 9% of the sheep are white, the frequency of white sheep is 0.09, or bb = 0.09, so b=.3, which means B = 1-b = 1-.3 = 0.7You should check to make sure that the hardy-weinburg assumption holds:BB = 0.492Bb = 0.42And BB + 2Bb = 0.91, which is the frequency of black sheep. ?The hardy-weinburg assumption is valid!

How do you use Allele Frequency in a sentence for biology?
Allele frequency refers to the proportion of a specific allele in a population's gene pool. For example, in a population of birds, the allele frequency for the gene that determines feather color might be 0.7 for the brown allele and 0.3 for the white allele.
Are alleles dominant or recessive?
Alleles are neither entirely recessive nor entirely dominate. An allele is any one of a number of alternative forms of the same gene on a chromosome.For example: say a flower only blooms either red or white flowers. There is a different allele for each color-- a red allele and a white allele. Now, one color may be dominate over the other recessive gene. For example, if the red color was dominate and the white color was recessive, then those certain alleles would be dominate and recessive, respectively. But alleles in general cannot be either recessive or dominate. It depends on the gene and it depends on the trait.
Out of 200 offspring of heterozygous brown rabbits and white rabbits how many white rabbits would be expected?
Half of the offspring, or 100 rabbits, would be expected to be white when offspring from a heterozygous brown rabbit and a white rabbit are produced. This is due to the dominant-recessive inheritance pattern where brown is dominant and white is recessive.
Is it possible for there to be recessive homozygous alleles?
Yes - recessive alleles can be eliminated from the gene pool. However, heterozygous individuals (those with one recessive allele) are harder to identify if the allele is recessive, so if talking about artificial (selective) breeding, the process may take some time.
If the allele for having a white forelock is dominant family members WITHOUT a white forelock are?
Family members without a white forelock must possess two recessive alleles for that trait, as the white forelock is dominant. This means they can only pass on the recessive allele to their offspring, ensuring that none of their children will have a white forelock unless the other parent contributes a dominant allele. In genetic terms, these family members are homozygous recessive for the trait.
What colors are recessive?
In genetics, recessive traits are those that require two copies of a recessive allele for the trait to be expressed. For example, in humans, the allele for blue eyes is recessive to the allele for brown eyes. Similarly, in plants, a recessive flower color might be white, while the dominant color could be purple. The specific colors considered recessive can vary depending on the species and the traits being examined.
