- Dominant genes are capable of producing a certain trait or characteristic when present in the chromosome pair. Even if a recessive gene allele is also present, the dominant allele takes precedence and determines the observable trait in the organism. The expression of dominant genes can override the presence of a recessive allele.

Dec 20, 2023 · Dominant genes are those that are expressed or “seen” in an organism’s physical traits, even if only one copy of the gene is present. They are the genes that override or mask the effects of recessive genes if both are present.
Dominant genes are capable of producing a certain trait or characteristic when present in the chromosome pair. Even if a recessive gene allele is also present, the dominant allele takes precedence and determines the observable trait in the organism.

A dominant trait is an inherited characteristic that appears in an offspring if it is contributed from a parent through a dominant allele. Traits, also known as phenotypes, may include features such as eye color, hair color, immunity or susceptibility to certain diseases and facial features such as dimples and freckles. In sexually reproducing spec...
Human Dominant Traits
There are many characteristics of the human phenotype, which are controlled by dominant alleles: Other traits, which are not physically visible, are also controlled by dominant alleles, for example: It is important to note that dominant alleles are not better than recessive alleles; dominant traits can cause serious health problems for individuals (such as high blood pressure). Dominant traits are also not necessarily more common than recessive traits; although, if they have an effect on the...
Just like in Mendel’s experiments, humans have been using genetics for selective breedingin animals, as well as fruit and vegetables, for thousands of years. Dominant traits that are favorable, such as white wool in sheep, smooth coats in horses, and short legs in dachshunds, can be increased in a population by breeding individuals who have the dom...
Recessive Traits– Recessive traits are phenotype characteristics, which are displayed when a gene has two recessive alleles at a locus within a chromosome.Genes– Made up of DNA, genes are the basic unit of heredity, which code for the expression and control of proteins.Genotype– The set of genes in each individual that is responsible for the expression of particular traits.Phenotype– The physical characteristics or traits that are expressed as a consequence of an organism’s genotype.1. The dominant trait in duck beaks is long length, controlled by the B allele. Short beaks are determined by the recessive allele b. If the mother duck is homozygous for long beak length (BB) and the father is heterozygous (Bb), what percentage of their offspring will have long beaks? A. 25% B. 50% C. 75% D.100% 2. Which of the following statement...
In this example, we will call the gene for cleft chin “B,” and the gene for smooth chin “b.” Cleft chin is a dominant trait, which means that having the dominant allele either from one parent (Bb) or both parents (BB) will always result in the phenotype associated with the dominant allele.

The gene that produces healthy, round-shaped red blood cells is dominant. The recessive gene causes an abnormality in the shape of red blood cells; they take on a sickle form, which can clog the veins and deprive vital organs of oxygen, increasing the risk of stroke.
