What is the organism that carries invisible traits?
genetic variation
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 is the type of variation where a characteristic can only result in certain values?
The type of variation where a characteristic can only take on specific, distinct values is called discrete variation. Unlike continuous variation, which allows for a range of values, discrete variation often involves traits that are categorical or countable, such as the number of petals on a flower or the presence or absence of a certain gene. This variation is typically influenced by genetic factors and can result in observable phenotypic traits.
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 causes variation of traits in a population?
the enviroment.
What does discontinuous variation mean?
Discontinuous variation refers to the type of phenotypic variation that falls into distinct categories or groups, with no intermediate forms. Traits exhibiting discontinuous variation, such as blood type or flower color, can be clearly classified into specific categories. This type of variation is often influenced by a small number of genes, making it easier to identify and study. Unlike continuous variation, where traits show a range of values, discontinuous variation results in a more discrete distribution of traits.
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.
Variation of human skin color is an example of?

By the end of the twentieth century biological research was demonstrating that about half of the variation in personality traits was due to what?

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 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.
