DevinRecessive 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
