Recessive disorders are more common than dominant disorders because carriers of recessive genes can pass on the disorder without being affected themselves. This means that individuals can carry the recessive gene without showing symptoms, leading to a higher chance of two carriers having an affected child. In contrast, dominant disorders require that at least one parent carrying the dominant gene must be affected, making them less common.

Recessive allele is more common or dominant allele?
Dominant alleles are more common than recessive alleles in a population. This is because dominant alleles are expressed in the phenotype when present, so they are more likely to be passed on to the next generation. Recessive alleles are hidden by dominant alleles when present together in a heterozygous individual.
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.
How do dominate traits over power the recessive?
Dominant traits are expressed over recessive traits because the dominant allele codes for a functional protein that masks the effects of the recessive allele. In a heterozygous individual carrying one dominant and one recessive allele, the dominant allele is expressed, leading to the dominant trait being observed.
Why do recessive trail are more common in some cases?
They're not necessarily, but they can be. When a recessive trait is more common, it likely because it was advantageous to have that trait so the species evolved to have more of it in the gene pool. Also, since dominant traits are expressed over recessive traits, natural selection has more of an effect on them.
What is the difference between dominant alleles and recessive alleles?
dominant-appears in first generation recessive-seems to dissapear

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 true that recessive disorders in offspring more common if the parents are closely related?
yes,of course
What is the difference between dominant and recessive gene?
There are no such things as dominant and recessive genes. There are only dominant and recessive alleles. Dominant alleles are parts of a gene that present its features over the recessive allele, which is the one that is always masked by the dominant allele. The recessive allele's trait only shows if both of the alleles in a trait are recessive.
How do dominate traits over power the recessive?
Dominant traits are expressed over recessive traits because the dominant allele codes for a functional protein that masks the effects of the recessive allele. In a heterozygous individual carrying one dominant and one recessive allele, the dominant allele is expressed, leading to the dominant trait being observed.

Would you expect there to be more children with the dominant phenotype or recessive phenotypewhy?
There would likely be more children with the dominant phenotype because it only requires one copy of the dominant allele to express the dominant trait, whereas the recessive phenotype requires two copies of the recessive allele.
What is difference between a dominant trait and a recessive trait?
A dominant trait is one that is expressed in an individual when only one copy of the gene is present, masking the effect of any recessive allele. In contrast, a recessive trait is only expressed when an individual carries two copies of the recessive allele. Dominant traits tend to be more common in populations compared to recessive traits.
What is the different between dominant and recessive?
Dominant traits are expressed when an individual carries at least one copy of the dominant allele, while recessive traits are expressed only when an individual carries two copies of the recessive allele. Dominant alleles mask the expression of recessive alleles in heterozygous individuals.
Can recessive genes become dominant?
Recessive genes do not become dominant. Dominant genes mask the expression of recessive genes in the presence of both alleles. However, if a recessive gene is selected for over time through breeding, it can become more prevalent in a population.
Why are some traits more common than others?
Characteristics that are more common than others are dominant. Recessive traits are not expressed when paired with a dominant trait.
