Is human skin colour continuous or discontinuous variation?
Natural eye colour is discontinuous. :) !
What is a continious variation?
eyes, hair, fingers and toes, vertebrates... most common body parts
How do organisms achieve variation?
The differences shown by the individuals of one kind of organisms are called variations. Variations are due to hereditary and non-hereditary characteristics. Characteristics, which are passed from parents to off spring, are called hereditary characteristics. In general the term variation means the difference in characteristics of organisms belonging to the same species in a natural population. Two types of variation, i.e. continuous and discontinuous, occur in any large population. In continuous variation, there are small differences among individuals of the same species and many intermediate forms are seen. So there is a complete gradation of many characteristics of organisms from one extreme to the other in a population. E.g. height in human being. Characteristics showing continuous variation are produced due to combined effects of many genes and environmental factors.
Type of selection in which human select the variation?
Artificial selection.
What does physical variation mean?
Physical variation refers to the differences in physical characteristics that exist within a population or species. These variations can include traits such as height, weight, skin color, facial features, and body shape, and are influenced by a combination of genetic, environmental, and developmental factors. Embracing and celebrating physical variation is important for promoting diversity and understanding the complexity of human biology.

What are types of variations?
There are 2 types of variation: Continuous and Discontinuous. Continuous: Has slight differences that grade into each other. Usually has quantitative/measurable characteristics. e.g Human height/weight... Discontinuous: It has discrete differences which have a clear cut- they do not merge into each other. e.g. human blood...
Is the variation in weight in human populations an example of discrete or continuous variation?
It is an example of continuous variations.

What is the variation in human skin color an example of?
This is a typical kind of continuous variation which is controlled by polygenes.

eyes, hair, fingers and toes, vertebrates... most common body parts
Why is height continuous variation?
You have the gene of tallness, but you don't eat enough so that your body size doesn't change. Continuous variation in human population is always the result of interaction between genotype and the environment
Is race a continuous variable?
Race is not considered a continuous variable; it is typically classified as a categorical variable. While genetic variation exists within and between populations, the social constructs of race are based on perceived physical characteristics and cultural identities rather than measurable, continuous traits. The complexities of human genetic diversity do not align neatly with racial categories, which can oversimplify and misrepresent the nuances of human variation.
What has the author N S Ossenberg written?

What are specific examples of variation within a species?
Human species, as in the variation in height.
What is a source of genetic variation in organisms?
Human recombination is a significant source of genetic variation.
