Random non-directional change in allele frequencies that occurs by chance in all populations and especially in small populations is known as:

Random unidirectional change in allele frequencies that occurs by chance in all populations and especially in small populations is known as

Variation in gene frequencies within populations can occur by chance rather than by natural selection. This is referred to as Or Random unidirectional change in allele frequencies that occur by chance in all population and especially in small populations is known as

Write one word for the following: Change in gene frequencies occur by change in small population.

If change in gene frequencies in a population occurs by chance, then it is called as:

If change in gene frequencies in a population occurs by chance, than it is called as:

Accidental fluctuation in alleles of small population is termed as
