Human species, as in the variation in height.
Within a species, the animals breed together so that the similar characteristics are passed from parents to their offspring. This is why there is less variation within a species than between a species.
Because there is variation within a species, it is therefore possible for the law of natural selection to operate, by selecting those variations which best enhance survival and reproduction.
When studying and proving the theory of evolution, Darwin notice that variations existed within species. Species includes organisms that are closely related and can mate to produce fertile offspring. Variation is a difference. Darwin noticed that there were more than one organism inside a species.
The term that describes changes within a species over time is "microevolution." This involves genetic variations that occur within a population, leading to changes in traits or characteristics in response to environmental factors.
The difference in characteristics between organisms of the same species is called "genetic variation." This variation can arise from mutations, sexual reproduction, and environmental factors, leading to diversity in traits such as size, color, and behavior within the species. Genetic variation is essential for natural selection and the overall adaptability of populations.
yes
Variations occurs in species due to the process of "Crossing over"
A variation in characteristics within populations of the same species is called intraspecific variation. This variation can occur due to genetic differences, environmental factors, and developmental processes, leading to diverse traits among individuals in the same species. Understanding intraspecific variation is crucial for studying evolution, ecology, and conservation.
Within a species, the animals breed together so that the similar characteristics are passed from parents to their offspring. This is why there is less variation within a species than between a species.
No, mango leaf is not considered a parallel variation. Parallel variation refers to easy and reversible changes within a species or population, while mango leaf characteristics are part of the natural variation within the species.
Genetic variation, caused by mutations in DNA, is a major source of variation within species. Mutations can lead to differences in traits such as color, size, and behavior, allowing for natural selection to act upon these variations.
In the context of snakes, the term "morph" refers to a specific color or pattern variation within a species.
It has adaptations
Variation exists within the genes of every population or species as the result of natural selection. The other reason is due to neutrality of mutations.
Because there is variation within a species, it is therefore possible for the law of natural selection to operate, by selecting those variations which best enhance survival and reproduction.
Yes, variation can sometimes hinder a species' survival. If a variant trait reduces an organism's fitness or adaptability to changing environments, it may lead to its decline. Additionally, excessive variation can lead to instability within a population, making it harder for the species to thrive under specific ecological pressures. Thus, while variation generally contributes to resilience, it can also pose risks in certain contexts.
Phenotype variation is slight variations in a phenotype that are caused by the expression of an organism's genes or the influence of environmental factors. A species can have several different phenotypes within it.
