What is the term that means a variation of traits?
The term that means a variation of traits is "phenotypic variation." This refers to the observable differences in physical and physiological traits among individuals in a population, which can be influenced by genetic factors and environmental conditions. Variations can include differences in height, color, and behavior, and are crucial for the processes of natural selection and evolution.
What are variation traits?
Variation traits are characteristics that can differ among individuals of the same species, such as height, eye color, or blood type. These traits are influenced by genetics and environmental factors, contributing to the diversity seen within a population. Variation traits play a key role in evolution by providing the raw material for natural selection to act upon.
What is the organism that carries invisible traits?
genetic variation
What is variation under domestication and variation under nature?
Variation under domestication refers to the diversity in traits of domesticated animals or plants resulting from selective breeding by humans. Variation under nature refers to the diversity in traits of wild organisms shaped by natural selection and evolutionary processes in their natural habitats.
What requires natural selection to occur in a population?
Natural selection requires variation in traits within a population, heritability of those traits, and differential reproductive success based on those traits. Without these components, natural selection cannot act on a population.

Variation of human skin color is an example of?
polygenic traits
How does the range of phenotype differ between single-gene traits and polygenic traits?
Single gene traits are either one type or another,for example everyone is either (ABO System) group A,B AB or O with no intermediates - this shows discontinuous variation. In polgyenic traits, continuous variation is shown and there is a range with no discrete categories - height
What causes variation of traits in a population?
the enviroment.
What is trait variation and can you provide an example to illustrate this concept?
Trait variation refers to the differences in characteristics or features among individuals within a population. This variation can be seen in traits such as height, eye color, or blood type. For example, in a population of sunflowers, some plants may have taller stems while others have shorter stems, demonstrating trait variation in the population.

What are the four steps of Darwin's theory of evolution by natural selection and examples?
Variation: Individuals within a population have differences in traits. (Example: Variation in beak size among Galapagos finches) Inheritance: Some of these traits are heritable and can be passed down from parents to offspring. (Example: Offspring inheriting their parent's eye color) Selection: Certain traits may provide a reproductive advantage, leading to increased survival and reproduction. (Example: Camouflaged moths surviving better in a polluted environment) Time: Over successive generations, these advantageous traits become more common in the population, driving evolutionary change. (Example: Giraffes evolving longer necks to reach taller trees for food)
What is example of discontinuous varitation?
Polydactyly, a condition where an individual has extra fingers or toes, is an example of discontinuous variation. These extra digits are distinct and discrete traits that can be observed in individuals within a population.
What is the organism that carries invisible traits?
genetic variation
What are the three types of variation?
The three types of variation are genetic variation, environmental variation, and genotype-environment interaction. Genetic variation refers to differences in DNA sequences among individuals, while environmental variation is differences in traits caused by external factors. Genotype-environment interaction occurs when the effect of genes on traits depends on the environment.
How do stabilizing and disruptive selection differ in terms of their impact on the genetic variation within a population?
Stabilizing selection maintains genetic variation by favoring the average traits, while disruptive selection increases genetic variation by favoring extreme traits.
By the end of the twentieth century biological research was demonstrating that about half of the variation in personality traits was due to what?
genetic variation
