dominant, predominant, paramount, preponderant mean superior to all others in influence or importance. dominant applies to something that is uppermost because ruling or controlling.
What is the definition of recessive 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.
What is the meaning of dominant and recessive in biology?
Dominant traits are always expressed when the connected allele is dominant, even if only one copy of the dominant trait exists. Recessive traits are expressed only if both the connected alleles are recessive. If one of the alleles is dominant, then the associated characteristic is less likely to manifest.
Which genes are dominant?
Dominant and recessive genes. 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 recessive simple?
: being or produced by a form of a gene whose effect can be hidden by a dominant gene and which can produce a noticeable effect only when two copies of the gene are present Blue eye color is a recessive trait.
What is recessive example?
Examples of Recessive Traits For example, having a straight hairline is recessive, while having a widow’s peak (a V-shaped hairline near the forehead) is dominant. Cleft chin, dimples, and freckles are similar examples; individuals with recessive alleles for a cleft chin, dimples, or freckles do not have these traits.
What is the difference between dominant and recessive allele?
A dominant allele produces a dominant phenotype in individuals who have one copy of the allele, which can come from just one parent. For a recessive allele to produce a recessive phenotype, the individual must have two copies, one from each parent.
What is an example of dominate?
To dominate is defined as to have or take control, or to get all the attention. An example of dominate is bossing everyone else around. An example of dominate is what happens when a new baby gets fussed over by everyone and gets all of the attention.
What is the most dominant gene?
Right-Handedness If you doubt that, think about how hard it was to get left-handed scissors in kindergarten. A whopping 70 to 90% of people are right handed, all because right-handedness is a seriously dominant gene.
What is your dominant trait?
A dominant personality is a personality type that often leads themselves and others into action. It’s primarily defined by an overarching motivation for power and a sense of pride. This doesn’t mean dominant personalities are always eager to obtain power or behave like tyrants.
Which gene is dominant male or female?
Paternal genes have been found to be more dominant than the maternal ones.
Are blue eyes recessive?
The brown eye form of the eye color gene (or allele) is dominant, whereas the blue eye allele is recessive. If both parents have brown eyes yet carry the allele for blue eyes, a quarter of the children will have blue eyes, and three quarters will have brown eyes.
What’s the opposite of recessive?
Antonyms for recessive. extroverted. (also extraverted), immodest, outgoing.
Is dark skin dominant or recessive?
Inheritance of Skin Color Each gene has two forms: dark skin allele (A, B, and C) and light skin allele (a, b, and c). Neither allele is completely dominant to the other, and heterozygotes exhibit an intermediate phenotype (incomplete dominance).
Is red hair dominant or recessive?
The gene for red hair is recessive, so a person needs two copies of that gene for it to show up or be expressed. That means even if both parents carry the gene, just one in four of their children are likely to turn out to be a redhead.
Which allele is dominant?
A dominant allele is denoted by a capital letter (A versus a). Since each parent provides one allele, the possible combinations are: AA, Aa, and aa. Offspring whose genotype is either AA or Aa will have the dominant trait expressed phenotypically, while aa individuals express the recessive trait.
What is meant by a dominant allele?
Definitions of dominant allele. an allele that produces the same phenotype whether its paired allele is identical or different. synonyms: dominant.
What genes are recessive?
A recessive gene is a gene whose effects are masked in the presence of a dominant gene. Every organism that has DNA packed into chromosomes has two alleles, or forms of a gene, for each gene: one inherited from their mother, and one inherited from their father.
What is dominant structure?
The concept of dominant structure Intuitively, the term dominant structure refers to some subset of the stock-and-flow1 feedback structure of a model that is principally responsible for a particular pattern of model behavior.
What is the difference between dominant and dominate?
The word dominate is a transitive verb, which is a verb that takes an object. It is derived from the Latin word, dominari, which means to govern or to rule. Dominant is an adjective that describes something that is supreme over others, something that is successful, something that is commanding.
Which eye Colour is dominant?
Eye color was traditionally described as a single gene trait, with brown eyes being dominant over blue eyes. Today, scientists have discovered that at least eight genes influence the final color of eyes. The genes control the amount of melanin inside specialized cells of the iris.
Who genes are more dominant mother or father?
Mother’s genes are usually 50% of a child’s DNA, and father’s genes are the other 50%. However, male genes are much more aggressive than female genes, that’s why they are usually more prominent. So, there are usually 40% active female genes and 60% active male genes.
Is height a dominant trait?
For example, the gene for having an extra finger is actually dominant, while the gene for having a tall stature is a recessive trait.
How do you know if you are a dominant?
- He exhibits self-control and self-discipline.

- He knows he’s a work in progress, and he does the work.
