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.

∙ 13y agoA recessive trait would appear more often than a dominant trait for two reasons. First, the dominant trait may be lethal, so that only those individuals with the recessive genotype will survive. Second, the majority of the alleles for a particular trait in a population may be recessive. This is the case for the number of digits on human hands. Almost everyone has five digits per hand, which is the recessive trait. This is because the vast majority of alleles for that trait are recessive in most populations. Very few people carry the dominant allele for six digits per hand. However there are isolated island populations in which the majority of people have six fingers.

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 color blindness a dominant or a recessive trait?
Color blindness is a recessive sex linked trait.
Why are recessive disorders more common than dominant disorders?
dominant traits show up in the first generation so any disorders have a 50% percent chance of showing up in offspring. recessive traits skip a generation therefore any diseases would have on a 25% chance.
Recessive allele is more common or dominant allele?
Not necessarily. I think the dominant genes are more common, but there are lot of exceptions out there. For example, having six fingers in humans is a dominant gene, but it isn't all that common.
How do dominate traits over power the recessive?
dominates it (you get the dominant form)
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.
What genotypic condition must be present for a recessive trait to be visible?
if the ratio had more recessive traits, like if you made a punnit square and you saw that there were more of the recessive traits (BB bb bb bb) then you know that the most common trait is the recessive one "bb" (considered as homozygous recessive ( i think))
Why is sex chromosome abnormalities are more common than autosomal abnormalities?
They are not "more common", but since they are not paired in the male there's no such thing as a recessive.
Is true that recessive disorders in offspring more common if the parents are closely related?
yes,of course
Is color blindness a dominant or a recessive trait?
Color blindness is a recessive sex linked trait.
Colorblindness is more common in males than in females because?
the allele for colorblindness is recessive and located on the X chromosomes
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.
Why are recessive disorders more common than dominant disorders?
dominant traits show up in the first generation so any disorders have a 50% percent chance of showing up in offspring. recessive traits skip a generation therefore any diseases would have on a 25% chance.
Recessive allele is more common or dominant allele?
Not necessarily. I think the dominant genes are more common, but there are lot of exceptions out there. For example, having six fingers in humans is a dominant gene, but it isn't all that common.
Why would recessive traits be more common on boys than girls?
Only sex-linked recessive traits on the X sex chromosome are more common in males. This is because males receive only one X chromosome, so they cannot be heterozygous for a trait on the X chromosome. Females inherit two sex chromosomes, so they can be heterozygous, receiving both a dominant and a recessive allele on the X chromosomes.
How did Mendel's views on inheritance differ from the views of many scientist of his time?
Mendel called the more common traits "dominant" and the less common ones "recessive."-Sami. (:
