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 dominant alleles recessive alleles differs?

Dominant alleles are the ones that show up in the phenotype. Recessive alleles do not unless both alleles are recessive, but can be passed on. For example: Tt , T=tall and t=short. Tall is dominant and short is recessive. You are tall and can pass on the short gene. Or, you can use black hair being dominant over red. Or, brown eyes being dominant over blue. Dominant can be seen on you and recessive can't.


Why are two recessive alleles needed for a recesssive trait to be shown?

bcoz in case of one dominant and one recessive, dominant allele will express its characters and suppresses the recessive ones. so for the expression of recessive characters both allele should be recessive.


What type of allele masks the expression of the recessive allele?

Two recessive alleles can not take over a dominant allele because there are only two alleles in a pair. This can only happen if there is a mutation because the dominant always takes over the recessive.


Why are recessive alleles not always expressed as the phenotype?

recessive alleles get masked to show the difference in a dominant gene and a recessive gene. the dominate genes masks the recessive genes to show that the dominate gene is more dominate or more likely to be the outcome than the reccessive gene but the masked gene is not always recessive.


What will always hide a recessive trait?

A dominant trait will always hide a recessive trait in an individual's phenotype because the dominant allele is expressed over the recessive allele in the presence of both alleles.

Why are some genes alleles dominant and recessive?

Genes have dominant and recessive alleles because of the way they interact with each other. Dominant alleles are expressed over recessive alleles because they carry instructions that override the instructions of the recessive allele. This dominance is determined by the specific genetic makeup and interactions within an organism.


What type of allele is masked when a dominant allele is present?

The recessive allele is masked when a dominant allele is present. Dominant alleles are expressed over recessive alleles in heterozygous individuals.

How are dominant and recessive genes?

If you are talking about traits, dominant traits and recessive traits both have alleles. Dominant traits are alleles that cover up the expression of other alleles. One dominant allele with one recessive allele makes a dominant trait. Two dominant alleles together also make a dominant trate. Recessive traits are alleles that are only expressed when there is no dominant trait to cover them up. Two recessive alleles make a recessive trait. Traits can be passed over to the next generation. Two alleles together make a genotype, which is the inherited combination of alleles. Alleles: different versions of the same gene. Heredity: determined by genes. Genes: piece of DNA that shows the cell how to make a protein it needs.

What is it when you have a gene pair that consist of two dominate alleles and two recessive alleles?

The name of the gene pair that consists of a dominant and recessive allele, i.e. (Xx) will be a heterozygous allele. In this situation, the characteristics of the dominant characteristic will mask that of the recessive allele. People have have a heterozygous genotype may be carriers for diseases that reside on the recessive allele.


How are dominant and recessive genes related?

Dominate them. Recessive alleles do not show in your phenotype unless you have two of the same recessive allele. But if you inherit one dominant and one recessive, it is the dominant that always shows in your phenotype.


What happens to a populations alleles as they change one time?

Evolution is the change in the frequency of alleles of a population of organisms over time.

How do dominant and recessive alleles affect an offsprings phenotype?

The traits inherited depends upon the alleles that have been passed on from the father and mother.The traits that are exhibited is called as the phenotype. Dominant allele needs only one copy to be expressed.For example in a pea plant "T" represents the tall dominant allele and "t" the short recessive allele .TT - when there are two dominant alleles the pea plant will express the tall trait. The pea plant is tall.Tt - when there is one dominant and one recessive allele the pea plant will still express the tall trait.In this case the dominant allele masks the recessive allele and the pea plant is still tall.tt - when there are two recessive alleles the pea plant will express the recessive trait and the pea plant is short.For a recessive trait to show up there should be a pair of recessive alleles.
