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 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.
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 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.
What does dominate and recessive mean?
Dominant and Recessive refer to different types of genes a child gains from its parents. In general, a dominant gene overpowers a recessive gene (like more people have brown eyes than blue eyes), but there are some cases where recessive genes are visible on a child over the dominant gene.
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 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))
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.
Is true that recessive disorders in offspring more common if the parents are closely related?
yes,of course
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.
Which gene dominates over the other in cases where one gene overtakes more than the other?
In cases where one gene dominates over another, it is known as dominant gene. Dominant genes are expressed more strongly than recessive genes.
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. (:

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.
