Definition of Genotype
According to the Encyclopedia Britaica, a genotype is defined as follows:
"Genotype, the genetic constitution of an organism. The genotype determines the hereditary potentials and limitations of an individual from embryonic formation through adulthood. Among organisms that reproduce sexually, an individual’s genotype comprises the entire complex of genes inherited from both parents. It can be demonstrated mathematically that sexual reproduction virtually guarantees that each individual will have a unique genotype (except for those individuals, such as identical twins, who are derived from the same fertilized egg).
The actual appearance and behaviour of the individual—i.e., the individual’s phenotype (q.v.)—is determined by the dominance relationships of the alleles that make up the genotype, along with environmental influences."
This is directly related to heredity and the kind of person individually we become. The same applies to the animal and botanical kindgdom. The
The Encyclopedia Britanica adds to this definition as follows:
"The set of genes that an offspring inherits from both parents, a combination of the genetic material of each, is called the organism’s genotype. The genotype is contrasted to the phenotype, which is the organism’s outward appearance and the developmental outcome of its genes. The phenotype includes an organism’s bodily structures, physiological processes, and behaviours. Although the genotype determines the broad limits of the features an organism can develop, the features that actually develop, i.e., the phenotype, depend on complex interactions between genes and their environment. The genotype remains constant throughout an organism’s lifetime; however, because the organism’s internal and external environments change continuously, so does its phenotype."
Please note that the genotype of any species prevents the particular species or organism from becoming into another species or organism. As it is very clear from its definition : " genotype determines the broad limits of the features an organism can develop". (emphasis ours).
While it is possible for an organism to achieve certain adaptation to the external environment, as explained by its phenotype changing process, it is axiomatically impossible for such or any organism to become into something else other than its own species. This is corroborated by the fact that "The genotype remains constant throughout an organism’s lifetime; however, because the organism’s internal and external environments change continuously, so does its phenotype." as expressed here by the Encyclopedia Britanica.
Researchers must carefully keep in mind that "In conducting genetic studies, it is crucial to discover the degree to which the observable trait is attributable to the pattern of genes in the cells and to what extent it arises from environmental influence", (or adaptation). (emphasis and bold ours).
Adaptation of the species is never related to evolution from one species to another as shown here. https://sites.google.com/site/dnageneticsresearch/did-darwin-s-finches-prove-evolution.
The fact that "that virtually all organisms on this planet have similar genetic systems" does not mean that each comes from the other or "evolved" from each other. Rather, it is the simple idea that they all have the same basic design and same basic structure as designed by the same person or organization. A trite example can be the fact that most Ford automobiles have some similarity in their design since Ford Motor Company is their original designer. Never in a billion years will anybody find that a Ford Truck or any of its cars transformes or "evolves" into a Honda SUV, or Prius hybrid vehicle, even though Ford Motor Company also manufactures and produces vehicles with virtual identical similarity such as their SUV's and or hybrid cars. https://www.ford.com/
Thus, another example is the fact that, "Although species differ in the sets of genes they contain, many similar genes are found across a wide range of species. For example, a large proportion of genes in baker’s yeast are also present in humans.".
Does that mean that humans come from yeast? That is a preposterous assumption. Evolutionists want to attribute gene similarities to a "common ancestor" by linking everyone and every organic matter to an initial "single cell", while in reality it is much simpler and much more logical to realize that any commonality is given by an intelligent Creator who used the same basic gene structure in order to Create all separate species.
