A person’s genotype is a collection of genes in their DNA that are responsible for their distinctive traits or characteristics. The phenotype, on the other hand, refers to the organism’s physical appearance or characteristics. With the use of a person’s genotype, we can discover their genetic code. Even if organisms appear to be identical, they may not share the same genetic make-up. The results of biological tests can reveal one’s genotype. It is also possible to express an individual’s phenotype in terms of genes or physical characteristics. Some examples of such characteristics are a person’s hair color, eye color, body form, and height, among others. A person’s genetics will have a role, but so will their environment. Phenotype vs. Genotype will be better understood after reading this article.
Genotype
The term “genotype” is used to describe the genetic makeup of an individual. A gene is a section of DNA that encodes a particular feature. It is possible for the nucleotide order of a gene to alter between copies of the same gene since each nucleotide consists of a phosphate group, such as sugar, and a base. As a result, a gene might take on different forms in different organisms. Alleles are commonly used to describe these many types. A locus can refer to both the precise location of a gene’s location on a chromosome as well as a stable position on a chromosome.
Phenotype
It’s possible for a diploid creature to receive two copies of the same allele or two copies of two different alleles from its parents when it’s born. Homozygous refers to an individual who has two alleles of the same type at the same locus. In contrast, if they have two distinct alleles at the same site, their genotype is considered heterozygous. Autosomal dominant and recessive alleles share the same gene. A person’s genotype is the result of the successive mix of alleles they have for a particular gene.
Phenotype is the term used to describe the characteristics of an organism.
The organism’s observable traits are a result of these. The phenotype, on the other hand, is not inherited from one’s parents, as is the case with genotype. A phenotype can be influenced by a person’s genotype as well as a slew of additional factors, including epigenetic alterations, the environment, and their way of life. The phenotypic is influenced by factors such as nutrition, temperature, humidity, and stress in the environment, which are all interconnected. When it comes to phenotype, flamingos are an excellent example. Their natural white appearance is a result of the pigments in the creatures they consume, which give them a bright, pink hue.
The amount and kind of melanin produced by us can be controlled by our genes. However, the darkening of existing melanin in sunny climates is caused by exposure to UV light, and this results in darker skin.
The following are some real-world examples to illustrate the distinction between phenotype and genotype:
The following are some examples of genotypes:
The color of one’s eyes is encoded by a gene. A brown or blue allele comes from the mother and a blue or brown one comes from the father.
A few other instances are the hues of your hair, your height, and the size of your shoes.
Height, wing span, and hair color are all phenotypes. Measurable factors such as hormones or blood cells are also included in this definition.
Difference between genotype and phenotype
|
Genotype |
Phenotype |
|
The organism’s genetic information is stored as a gene in its DNA and does not change over time. |
Phenotypes are the visible characteristics of an organism. |
|
There is no difference in phenotype amongst individuals with the same genotype. |
Genotype and phenotype may or may not be related. |
|
As genetic material, it is present in the body. |
Outward manifestation of genetic expression. |
|
Parents and children share the same genetic makeup. |
The phenotype is not passed down through the family tree. |
|
Scientific procedures, like the polymerase chain reaction, can be used to ascertain this. |
An organism’s behavior is enough to tell you what it is. |
|
Genes play a role in this. |
Environmental and genetic factors play a role |
|
For eg., Blood group, eye colour, height, genetic diseases. |
For eg., Weight, physique, beak of birds |
Conclusion
From the following article we can conclude that A person’s genotype is a group of genes in their DNA that make up their unique traits or characteristics. The phenotype, on the other hand, refers to how the organism looks or what it does. With the help of a person’s genotype, we can figure out their DNA code. Even if organisms look the same, they may not have the same DNA. The results of biological tests can show one’s genetic make-up. It is also possible to talk about an individual’s phenotype in terms of genes or physical traits.
