That depends on what the allele codes for, and the natural selection pressured on them.
for example: say we have a population of rabbits with Bb genes, where the B allele codes for a dominate black trait and b codes for a recessive brown trait. If the landscape is black and the rabbits need to blend in to avoid predators then the dominate black fur color is selected over generations. If the landscape is brown then the recessive trait will be selected for. In the dominantly selected group the recessive gene could still exist, just covered up the dominate gene phenotypically (they can be Bb or BB genotypes). In the recessively-selected group only the recessive gene is left (bb genotypes only).
What else can I help you with?
Why are recessive alleles not removed from populations over time?
If the recessive genotype is selected for more often than the dominant genotype, the recessive allele will become more common than the dominant allele in the gene pool.
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.
Does a recessive allele need another recessive allele to be expressed?
Yes, a recessive allele needs to be paired with another recessive allele in order to be expressed. This is because recessive alleles are only expressed when an individual has two copies of the recessive allele, one from each parent. If an individual has one dominant allele and one recessive allele for a particular trait, the dominant allele will be expressed.
What is q2 in Hardy-Weinberg equation?
In the Hardy-Weinberg equation, q2 represents the frequency of homozygous recessive individuals in a population for a specific allele. It is calculated by squaring the frequency (q) of the recessive allele in the population.
What is the term for an allele that is not expressed in the phenotype of a heterozygous individual?
incomplete dominance source: PH Bio textbook
What is allele masked by the dominant allele?
An allele that is masked by the dominant allele is called a recessive allele. When an individual has one dominant allele and one recessive allele, only the trait determined by the dominant allele will be expressed. The recessive allele will only be expressed if an individual has two copies of it (homozygous recessive).
Why are recessive alleles not removed from populations over time?
If the recessive genotype is selected for more often than the dominant genotype, the recessive allele will become more common than the dominant allele in the gene pool.
Is albinism controlled by a dominant allele or by a recessive allele?
Recessive allele.

Would a recessive allele or dominant allele be more common in population?
Dominant allele because its more likely to be received by the next generation.
Is albinism controlled by a dominant allele o recessive allele?
It is controlled by a recessive allele.
What allele is covered up by the dominant allele?
An allele that's masked by a dominant gene is called a "Recessive"recessiverecessive traitThe recessive allele. Often depicted as the "small r" in examples: Rr, R=dominant, r= recessive.
An allele that is hidden by other alleles is called?
i think the answer your lokking for is recessive Recessive is when you have a trait in your genome but it doesn't show in your physical appearance
How is a recessive allele from a dominant allele?
its different because adominant allele is in charge
