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.

On a punnet square dominant genes are represented by capital letters while recessive ones are lower case, recessive genes are those such s blue eyes or orange hair and are less common then dominant genes while dominant genes are those that represet more common things like brown eyes or blong hair. You need to have two recessive genes to have a recessive trait, but only one dominant gene is requirerd to have a dominant trait.

With a dominant gene it means it is much much more likely to show up than a recessive gene. For example your mom has blue eyes and your dad has brown eyes. 3 out of four time you are going to wind up with brown eyes because that is the dominant gene.

Dominant genes over power the recessive genes, so if you have one dominant and one recessive, you will see the effects of the dominant gene.

What is the difference between homzyguos and heterozyous?

Homozygous recessive: is when the genes are both recessive Homozygous dominant: is when the genes are both dominant (traits show) Heterozygous dominant: is when one gene is dominant and one is recessive (traits show) Heterozygous recessive: is the same as heterozygous dominant but the dominant genes are inactive


What is the different between dominant and recessive?

Dominant trait is the one which is expressed when the homologous pair of genes controlling it are either homozygous or Hetrozygous dominant; on the other hand recessive trait has both genes to be homozygous recessive. in fact trait is controlled by the form of genes. Dominant gene expresses even when it is in the company of recessive gene. However recessive gene expresses only when in company of recessive gene


Genes that are only seen when paired with a recessive gene?

if u have a recessive gene with a recessive gene then u can see the recessive gene but if you have a dominant gene with a recessive gene you can only see the dominant gene hope that helps:)


What is a dominant gene and what is a recessive gene?

Recessive gene is one which is supressed and do not show their characteristics and dominant gene is one which show their characteristics for example if a father has brown hair and mother has black hairs and if their son has black hair then in this case gene which has characteristics of black is dominant and the other which has characteristics of brown colour is recessive


Which form of gene pair is expressed when both dominant and recessive are present?

If the gene is governed by a dominant and recessive allele, then if the dominant allele is present, the dominant trait will be expressed. If both alleles are recessive, then the recessive trait will be expressed.

Can a recessive gene be hidden from a dominant?

The dominant gene will always "cover up" the recessive gene, although there are instances of codominance, in which both phenotypes will be displayed, because one gene is not completely dominant over the other. There is also what is called 'incomplete dominance', when the actual phenotype is somewhere between the two.

What is an organism that has a dominant and a recessive copy of a gene?

dogs have a dominant and a recessive copy of a gene


A gene is recessive when?

Most genes have two copies of each gene with dominant gene "trumping" the recessive one. The gene is recessive because it is said not to do much of anything unless paired with another recessive gene, but if paired with a dominant gene, the dominant gene wins.


Is a situation in which a dominant allele completely masks a recessive allele for a gene.?

If you have 2 dominant alleles, the gene will be dominant, if you have 2 recessive alleles, the gene will be recessive. But if you have 1 recessive and 1 dominant, the Dominant allele will mask the recessive one.


What is the opposite of homozygous of dominant?

heterozygous recessive


How many copies of a recessive gene does it take to overpower a dominant gene?

It takes 8 copies of a recessive gene to overpeower dominant gene


What is the difference between a dominant gene and a recessive gene?

In some but not all cases a dominant gene is a functional version (allele) of that gene while a recessive gene is a nonfunctional (or less functional) version (allele) of that gene. As the dominant gene produces a fully normally functioning protein if it is inherited in even just one copy that protein will "dominate" over the protein produced (if any is produced) by the recessive gene. Sometimes there are multiple different dominant alleles and/or multiple different recessive alleles of a specific gene (e.g. human blood types have 2 dominant alleles: A and B that produce different antigen proteins and 1 recessive allele: O that produces no antigen protein).


When one gene expresses itself over another the former gene is said to be the DNA?

The gene that expresses itself over the other is Dominant. The former gene is recessive.
