Is intelligence a continuous variation? Continuous Variation and Intelligence. Intelligence is an example of the inheritance of a complex or quantitative character. The nature of intelligence is composite and complex, and its expression is dependent upon a combination of environmental effects and the products of a great number of genes.
is height an example of continuous variation?Height is an example of continuous variation - individuals can have a complete range of heights, for example, 1.6, 1.61, 1.62, 1.625 etc metres high. Continuous variation is the combined effect of many genes (known as polygenic inheritance) and is often significantly affected by environmental influences.
Is foot size continuous or discontinuous? For any species a characteristic that changes gradually over a range of values shows continuous variation. Examples of such characteristics are: height. foot length.
Why Is height a continuous variation? Human height is an example of continuous variation. It ranges from that of the shortest person in the world to that of the tallest person. Any height is possible between these values. For any species a characteristic that changes gradually over a range of values shows continuous variation.
What are the 3 types of genetic variation? There are three sources of genetic variation: mutation, gene flow, and sexual reproduction. A mutation is simply a change in the DNA. Mutations themselves are not very common and are usually harmful to a population. Because of this, mutations are usually selected against through evolutionary processes.
What is an example of variation? Examples of genetic variation include eye color, blood type, camouflage in animals, and leaf modification in plants.
Why is human variation important?
It can help scientists understand ancient human population migrations as well as how human groups are biologically related to one another. For medicine, study of human genetic variation may be important because some disease-causing alleles occur more often in people from specific geographic regions.
Is height discrete or continuous?
Explanation: Discrete data is data where it has to be from a certain set of values e.g a shoe size can only be a certain value. The height is continuous as the height could take multiple values e.g from 10m all the way up 18.95m.
Is eye color discrete or continuous?
And clearly hair color, skin color and eye color all fall under the definition of a continuous trait, because even though they dont seem to be affected by the environment, they are definitely polygenic traits and show a gradation, so they're definitely continuous traits.
Is Skin Colour discrete or continuous?
Continuous variations are differences in characteristics that have a range of possible variations, such as height, shoe size, hand span, skin color, hair color, etc. Discrete variations are differences in characteristics that have a definite form, with a limited number of possibilities.
How is variation important?
Genetic variation is an important force in evolution as it allows natural selection to increase or decrease frequency of alleles already in the population. Genetic variation is advantageous to a population because it enables some individuals to adapt to the environment while maintaining the survival of the population.
What do u mean by variation?
Variation, in biology, any difference between cells, individual organisms, or groups of organisms of any species caused either by genetic differences (genotypic variation) or by the effect of environmental factors on the expression of the genetic potentials (phenotypic variation).
Do all humans have the same genome?
The human genome is mostly the same in all people. But there are variations across the genome. This genetic variation accounts for about 0.001 percent of each person's DNA and contributes to differences in appearance and health. People who are closely related have more similar DNA.
How closely related are humans?
Humans, chimpanzees, gorillas, orangutans and their extinct ancestors form a family of organisms known as the Hominidae. Researchers generally agree that among the living animals in this group, humans are most closely related to chimpanzees, judging from comparisons of anatomy and genetics.
How does the environment affect variation?
Environmental causes of variation Characteristics of animal and plant species can be affected by factors such as: For example, you will become heavier if you eat too much food, and you will become lighter if you eat too little. Variation caused by the surroundings is called environmental variation .
