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.
How do you explain dominant and recessive traits?
Dominant and recessive traits exist when a trait has two different forms at the gene level. The trait that first appears or is visibly expressed in the organism is called the dominant trait. The trait that is present at the gene level but is masked and does not show itself in the organism is called the recessive trait.
What is dominant explain with example?
Dominance, in genetics, greater influence by one of a pair of genes (alleles) that affect the same inherited character. If an individual pea plant with the alleles T and t (T = tallness, t = shortness) is the same height as a TT individual, the T allele (and the trait of tallness) is said to be completely dominant.
How do you explain dominant alleles?
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.
Are dimples dominant or recessive?
Dimples are usually considered a dominant genetic trait, which means that one copy of the altered gene in each cell is sufficient to cause dimples. However, some researchers say that there is no proof that dimples are inherited.
What is dominant character?
Definition. (genetics) An inherited trait that results from the expression of the dominant allele over the recessive allele. Supplement. The inheritance of one or two copies of the dominant alleles results in the expression of a dominant trait.
What is the rarest dimple?
In what researchers called a rare phenomenon, its possible that a person can possess a unilateral dimple: just one lone dimple on either the left or right side of his or her face. Even rarer than this sort of dimple, though, is the fovea inferior angle oris — aka one dimple on each side of the mouth corners.
Is having dimples good or bad?
There are many benefits of dimples in different cultures. According to many cultures and traditions, the formation of the dimple is a good sign. It indicates beauty, happiness, and luck. People believe that those with dimples are not only lucky to have dimples, yet they have been blessed with good luck!
What is a dominant character in literature?
dominant character a mendelian character that is expressed when it is transmitted by a single gene. recessive character a mendelian character that is expressed only when transmitted by both genes (one from each parent) determining the trait.
