What is heritable variation?
Heritable variation is the variation in characteristics caused by genetic factors.
What causes the variation in pitch?
it is caused when the variation is hit on the guitar
What causes varation in traits?
Genotypic variation is caused by mutation. Phenotypic variation can be caused by mutation, which gives rise to different alleles, or it can be caused by environmental factors.
What is variation in evolution?
A variation of a gene is called and allele. Different alleles are caused by mutations.
What is variation caused by?
It is caused by crossing over in sexual reproduction and random mutations in DNA.
Global pressure belts are caused by?
Temperature variation.
What is the observation of a wet spot on a hot highway in the summer caused by?
This is caused by refraction. A variation in air density corresponds to variation in refractive index of the air, locally near the road.
Is it true that seasonal variation is caused by the earth's eliptical orbit around the sun?
No, it is not.
What causes variation within societies?
Variation within societies can be caused by factors such as individual differences, cultural diversity, socioeconomic disparities, and historical events. These factors can lead to differences in beliefs, values, behaviors, and opportunities among members of a society.
When the only sources of variation in a production process are caused by chance the process is said to be?
In process control.
Why are mutations in body cells NOT a source of genetic variation?
They happen after the organism has been born, and often lead to tumours and cancer (caused by carcinogens). Other types of mutations can be caused by mutagens, which mutate the DNA of a cell. It doesn't affect the DNA of every cell in the organism/ reproductive cells, so isn't passed on to offspring
Disc thickness variation may be caused by?
Calipers that are not operation correctly, dragging the brake pedal which then heats and could distort the discs, Slamming on the brakes. Any of the above are most likely why you have a variation in disc thickness
