Genes which take precedence over their opposite number - recessive genes. i.e. when the genetic make-up of an organism is being determined the dominant gene will out-rank any recessive gene and more often than not be the determinant one.

∙ 11y agoA dorminant gene is a gene that clearly expresses itself phenotypically in an organism or in the offspring of an organism... For example in : T t - the dominant gene is the "T" which stands for Tallness and "t " for shortness.
When there is a cross between TT & Tt parents, all the offsprings would be TALL because the genetic outcomes would be: TT,Tt,TT and Tt- all having the dominant gene "T" .

Dominant gene plus Dominant gene?
It would be definite that you have that gene or trait.
What does it mean to be heterozygous for a gene?
homozygous mutant means both alleles of a gene are mutated.
To have blond hair do both of your genes have to be for blond hair?
not necessarily.ok there are two parents each giving the child one gene. if one gene is recessive and one is dominant the dominant gene will decide the hair color. example the recessive gene is black hair and the dominant gene is blonde the child will most likely have blonde hair because the dominant gene is blonde hair. the dominant gene masks the recessive gene
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
How do you symbolize a dominant gene?
a dominant gene is symbolized by a capital letter. a recessive gene is symbolized by a lower case letter.
Dominant gene plus Dominant gene?
It would be definite that you have that gene or trait.
Is the Huntingtons gene inherited as a dominant or ressisive gene?
It is inherited by a dominant gene.
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.
What is a homozygus?
When two cells have the same gene type then they are considered homozygous.
What is a sentence for dominant gene?
Dominant gene can be passed down from person to person
Is autism caused by a dominant gene?
yes , autism is caused by a dominant gene
What gene is defined as a gene that controls the appearance of a certain trait?
the dominant allele
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 an organism that has a dominant and a recessive copy of a gene?
dogs have a dominant and a recessive copy of a gene
What gene will exhibit its traits even in a prensesce of a recessive gene?
The dominant allele
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.
To have blond hair do both of your genes have to be for blond hair?
not necessarily.ok there are two parents each giving the child one gene. if one gene is recessive and one is dominant the dominant gene will decide the hair color. example the recessive gene is black hair and the dominant gene is blonde the child will most likely have blonde hair because the dominant gene is blonde hair. the dominant gene masks the recessive gene
