Variation in Genotypes result in variations of Phenotypes which lead to the Possibility of Biological Development that did end up being Survival of the Fittest.
Genetic variation allows organisms to adapt to changing environments and resist diseases. This diversity increases the chances of some individuals surviving and reproducing, passing on beneficial traits to future generations.

Organisms' survival strategies vary in terms of variation and adaptation. Variation refers to the differences among individuals within a species, which can provide a range of traits that may be beneficial in changing environments. Adaptation, on the other hand, involves specific traits that have evolved to help an organism survive and reproduce in its environment. Organisms may use both variation and adaptation to increase their chances of survival in different situations.
Survival of the fittest.
By the process of natural variation and selection by survival of the fittest.
An allele is a variant form of a gene that determines a specific trait. Alleles contribute to genetic variation in organisms by creating different combinations of traits through genetic recombination during reproduction. This variation allows for diversity within a population, which can lead to adaptations and evolution over time.
Basic source of variation in all organisms is mutation .
During reproduction, a pair of chromosomes from each parent combine to create a unique genetic makeup for the offspring. This process leads to genetic inheritance and variation in organisms, as the combination of genes on the chromosomes determines the traits and characteristics of the offspring.
Variation between cells refers to differences in their structure, function, or genetic makeup. This diversity allows organisms to adapt to changing environments and perform specific tasks efficiently. It is crucial for the survival and evolution of living organisms.
Organisms can acquire variation through genetic mutations, which are changes in the DNA sequence. These mutations can occur spontaneously or be introduced through processes like recombination. Additionally, environmental factors can also contribute to variation by influencing gene expression and phenotype.
Natural selection ' selects ' from among variations. Some organisms are better suited to their immediate environment and survive and out reproduce other organisms. All these organisms are genetically variant. That is the simple connection between natural selection and genetic variation. ( that variation coming about by mutation and recombination )
Variation in organisms is expressed through differences in their genetic makeup, which can result from mutations, gene shuffling during reproduction, and environmental influences. These genetic differences manifest in observable traits, such as physical characteristics, behaviors, and physiological responses. Additionally, variation can be influenced by natural selection, where certain traits may provide a survival advantage, leading to their increased prevalence in a population over time.
