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.
What is the definition for variation?
Variation refers to the degree of difference or diversity among individuals within a population or species. It can involve differences in traits, characteristics, or behaviors, which can be shaped by genetic, environmental, and other factors. Studying variation is important in understanding evolution, adaptation, and biodiversity.
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 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 the organism that carries invisible traits?
genetic variation
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 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.
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
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 is the difference between a trait and variation?
A trait is a specific characteristic or feature of an organism, such as eye color or height. Variation refers to the differences in traits within a population, which can be caused by genetic factors or environmental influences. In other words, traits are the specific manifestations, while variation describes the range or diversity of those traits among individuals.
What is an example of a physiological buffer?
