Why do cheetahs have very little genetic variation?
Even though the number of cheetahs grew to as many as 100,000 during the 19th century, their genetic variability remained low due to the extreme bottleneck event that took place thousands of years previously.
What are the two types of variation?
There are two forms of variation: continuous and discontinuous variation.
What is variation example?
The individual members of a species also have differences in characteristics. For example, humans have different coloured eyes, and dogs have different length tails. This means that no two members of a species are identical. The differences between the individuals in a species is called variation.
What type of variation is height?
continuous variation
What is the advantage of variation?
Advantage of Variation The advantage of having variation within a population is that some individuals will be better adapted to their environment than others. Those individuals who are not well adapted to their environment are less likely to survive and reproduce.
What you 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). …
How do you find a direct variation?
Direct variation problems are solved using the equation y = kx. In this case, you should use d for distance and t for time instead of x and y and notice how the word “square” changes the equation. Step 2: Use the information given in the problem to find the value of k.
What do all variation problems have in common?
Variation problems involve fairly simple relationships or formulas, involving one variable being equal to one term. Here follows the most common kinds of variation. Another form of variation is the inverse variation which works when there is a relationship between two variables in which the product is a constant.
Which is an example of a joint variation?
When a variable is dependent on the product or quotient of two or more variables, this is called joint variation. For example, the cost of busing students for each school trip varies with the number of students attending and the distance from the school.
