What does cline mean in biology?
What does cline mean in biology?
A cline is a gradient of a phenotypic or genetic character within a single species. The geographic distances across which characters shift can range from meters to thousands of kilometers.
What is a cline in evolution?
A cline is a geographic gradient in the frequency of a gene, or in the average value of a character. It can also arise if two forms are adapted to different environments separated in space and migration (gene flow) takes place between them. Geographic variation normally exists in the formof a continuous cline.
What is a cline biology example?
A cline is the specific set of traits in a population of a given species that have been influenced by the local environment. For example, a population of warm-blooded animals that lived in a cooler climate closer to the North Pole would have larger bodies, allowing them to better conserve heat.
What is meant by cline?
Definition of cline (Entry 1 of 2) : a gradient of morphological or physiological change in a group of related organisms usually along a line of environmental or geographic transition.
What is Cline Give 5 example?
freezing, cold, chilly, nippy, cool, mild, warm, hot, boiling, sweltering.
What causes Cline?
Clines are often cited to be the result of two opposing drivers: selection and gene flow (also known as migration). Selection causes adaptation to the local environment, resulting in different genotypes or phenotypes being favoured in different environments.
What is Cline in English and example?
A word cline is a scale of language items that goes from one extreme to another. For example, when talking about temperature we can choose from a range of words: freezing, cold, cool, warm, hot, boiling.
What is ecotype in biology?
An ecotype is a population (or subspecies or race) that is adapted to local environmental conditions. Thus, the adaptations of these ecotypes are based on the interactions of their own special sets of genes with their own environment.
How do you use Cline in a sentence?
Crazy will always be owned by Cline – her version of the song is the definitive one – but she didn’t write it. Cline hated the song when she heard the demo, but agreed to record it when her producer slowed down the music. From there, she toured with several popular country stars including Johnny Cash and Patsy Cline .

- whisper, say, mumble, talk, speak.
- chilly, freezing, warm, frosty, nippy.
- small, huge, tiny, big, enormous.
What produces gene flow?
Gene flow is the movement of genes into or out of a population. Such movement may be due to migration of individual organisms that reproduce in their new populations, or to the movement of gametes (e.g., as a consequence of pollen transfer among plants).
What is the definition of a cline in biology?
Biology. the gradual change in certain characteristics exhibited by members of a series of adjacent populations of organisms of the same species.
How are clines both biologically and geographically continuous?
In continuous clines, all populations of the species are able to interbreed and there is gene flow throughout the entire range of the species. In this way, these clines are both biologically (no clear subgroups) and geographically (contiguous distribution) continuous.
Which is an example of a cline type of evolution?
Another example of this cline type of evolution is the development of insect strains resistant to an insecticide that has been applied heavily in an area for several years. In many parts of the world houseflies became highly resistant to DDT.
How is the body size of an animal related to the Cline?
For example, the body size in a species of warm-blooded animals tends to be larger in cooler climates (a latitudinal cline), while the flowering time of a plant may tend to be later at higher altitudes (an altitudinal cline).
