What type of variation is fingerprints?
option c is very correct, size, colour and fingerprints, are all examples of morphological variation. morphological variations are those differences in the physical appearance of organisms of the same species. physiological variation deals with how the body functions.
What are examples of 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. So it is continuous variation.
Is intelligence continuous or discontinuous variation?
Those characteristics that are determined by the joint action of many genes, and intelligence and stature are two examples, are called quantitative characters because they are measured on a continuous scale. Such characters are more susceptible to environmental influences than are the polymorphisms.
Which one of the following is an example of discontinuous variation?
Human blood group is an example of discontinuous variation. In the ABO blood group system, only four blood groups are possible (A, B, AB or O). There are no values in between, so this is discontinuous variation. Here are some examples: blood group, sex (male or female), eye color etc.
What are the 2 types of variation?
There are two forms of variation: continuous and discontinuous variation.
What is continuous variation and examples?
Examples of continuous variation include things like a person’s height and weight. Examples of discontinuous variation include a person’s blood group or the color of a species of bird. These variations can exist for two major reasons.
Is blood group A continuous variation?
Human blood group is an example of discontinuous variation. There are no values in between, so this is discontinuous variation.
Is Skin Colour a continuous variation?
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.
What is meant by continuous variation?
For any species, a characteristic that changes gradually over a range of values shows continuous variation.
Is continuous variation inherited?
Continuous variation is the combined effect of many genes (known as polygenic inheritance) and is often significantly affected by environmental influences.
How does continuous variation occur?
Two reasons for continuous variation: Differences in external environmental conditions also produce continuous variation. In nature, each character will be influenced by many environmental variables, some tending to increase it, others to decrease it.
What is variation and its types?
Variations are the differences in the genetic makeup or phenotype of various organisms. Variations arise due to mutation, recombination at the time of gamete formation or due to environmental factors. Variations can be categorised into two types: These are caused due to mutation, recombination, etc.
What is the main cause of variation?
The two main causes of variation are mutation and genetic recombination in sexual reproduction.
What are the 2 causes of variation?
Major causes of variation include mutations, gene flow, and sexual reproduction. DNA mutation causes genetic variation by altering the genes of individuals in a population. Gene flow leads to genetic variation as new individuals with different gene combinations migrate into a population.
What are the factors causing variation?
Genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism’s offspring).
What is inherited variation in natural selection?
Genetic variation is the presence of differences in sequences of genes between individual organisms of a species. It enables natural selection, one of the primary forces driving the evolution of life.
