Question

What is the correct term for variation in characteristics within populations of the same species?

Answer 1

Answer:

Variation in characteristics within same species:

Explanation:

The variation of characteristics that take place within populations of the same species can be of two types, namely Genetic variation and Genetic drift.

• Genetic variation: The genetic differences or change in characteristics takes place naturally among the populations of the same species is called genetic variation. This type of variation allows the species to survive even during the fluctuating environment circumstances.
• Genetic drift:  The genetic variations that take place due to random fluctuations in a number of alleles (alternative form of genes that are found on a chromosome) in a population is called genetic drift. This takes place especially in small populations where random alleles face a greater risk of being lost due to environmental conditions.

Answer 2

Answer:

The correct term for variation in characteristics within populations of the same species is ‘gene pool’.

The genetic variation within a specific population is usually measured as per the total number of various alleles of all the genes as well as the frequency of their occurrence.

If there are a number of allelic forms of all genes and if there are number of combinations, then the variation is said to be high.
