A dominant allele is a variation of a gene that will produce a certain phenotype, even in the presence of other alleles. A dominant allele typically encodes for a functioning protein. The allele is dominant because one copy of the allele produces enough enzyme to supply a cell with plenty of a given product.

FAQs
Dominant Meaning In Biology? ›
Dominant refers to the relationship between two versions of a gene. Individuals receive two versions of each gene, known as alleles, from each parent. If the alleles of a gene are different, one allele will be expressed; it is the dominant gene. The effect of the other allele, called recessive, is masked.
What does dominant and recessive mean in biology? ›The most common interaction between alleles is a dominant/recessive relationship. An allele of a gene is said to be dominant when it effectively overrules the other (recessive) allele. Eye colour and blood groups are both examples of dominant/recessive gene relationships.
What is an example of dominant in biology? ›For example, the allele for brown eyes is dominant, therefore you only need one copy of the 'brown eye' allele to have brown eyes (although, with two copies you will still have brown eyes). If both alleles are dominant, it is called codominance.
What is the importance of dominant in biology? ›The dominant allele produces a certain phenotype (observable changes in physical characteristics). A dominant allele preferably expresses the functions of proteins. Why does an allele become dominant? This is because the dominant copy of the gene produces enough enzymes to give a cell the required material and code.
What does dominate mean in medical terms? ›Dominant: A genetic trait is considered dominant if it is expressed in a person who has only one copy of that gene. (In genetic terms, a dominant trait is one that is phenotypically expressed in heterozygotes).
What's the difference between dominant and recessive? ›What the difference between dominant and recessive genes? ANSWER: Dominant is always expressed when present. Recessive is only expressed when no dominant genes are present.
What does recessive mean in biology? ›Refers to a trait that is expressed only when genotype is homozygous; a trait that tends to be masked by other inherited traits, yet persists in a population among heterozygous genotypes. © Nature Education. Further Exploration.
What is a simple example of dominant? ›Freckles, cleft chin and dimples are all examples of a dominant trait. Having almond-shaped eyes is a dominant trait whereas having round eyes is a feature controlled by recessive alleles. The trait of detached earlobes, as opposed to attached earlobes, is dominant. Right-handedness is dominant over left-handedness.
What does dominant mean and give an example? ›If you're dominant, it means you treat others as if you're their master. You can also use dominant to describe something frequent or common. For example, when cell phones first came out, their dominant use was for making calls.
What does it mean to be a dominant? ›ruling, governing, or controlling; having or exerting authority or influence: dominant in the chain of command. occupying or being in a commanding or elevated position.
Why do species become dominant? ›
In the ecological environment, the dominance of species depends on many factors like moisture, groundwater condition, and temperature. Ecological dominance impacts competition.
What is the role of a dominant? ›A Dominant exercises control not by being overbearing or through the use of threats or by belittling another, but rather by working on a more subtle level, influencing thoughts, desires, needs and hopes – and through the simple expedient of showing they care.
Which genes are more dominant? ›And while it is true that you get half of your genes from each parent, the genes from your father are more dominant, especially when it comes to your health.
What does dominant mean in pathology? ›“Dominant” means that a single copy of the mutated gene (from one parent) is enough to cause the disorder. A child of a person affected by an autosomal dominant condition has a 50% chance of being affected by that condition via inheritance of a dominant allele.
Is dominant positive or negative? ›While a dominant personality is often associated with negative traits of aggression and manipulation, there are many positive traits to be recognized, as well. Dominant people can be strong leaders, dedicated, and goal-oriented.
What does it mean to be high dominant? ›A person with high dominance has many ideas and opinions, and he's keen to share them with those around him. He is hands-on and focused on producing results. He values independence and autonomy above all.
What is the difference between dominant and recessive and give an example of each? ›Earthy tinted eye tone is a dominant trait. Recessive traits refer to the smallest unit of inheritance in all living things, and they may take several different forms called alleles. People usually have two alleles for each characteristic.
What is the difference between dominant and recessive parent? ›Autosomal dominant traits pass from one parent onto their child. Autosomal recessive traits pass from both parents onto their child. Autosomal refers to the 22 numbered chromosomes as opposed to the sex chromosomes (X and Y).
