When is genetic drift a major factor of evolution?

When there is low gene flow

When there is a lower genetic flow.

Explanation:

Genetic drift is a major factor of evolution when the organism population size is small. In such a population, the random change in the allele frequency that is not a response to a selective pressure can become fixed in a population. The random change in population is called genetic drift.

The genetic drift is a major factor in evolution when there is lower gene flow and when there is no selective pressure and when there is a bottleneck in the environment.

label a cell membrane

label b cytoplasm

label c ribosomes

label d dna

the membrane forms the outside of the cell

cytoplasm is the liquid within

ribosomes are the components within that distribute rna

the dna is the genetic make-up

the answers are as following:

1. c. double helix, nucleosome, coil, supercoil, chromosome

2. b. g2 phase, preparation for mitosis

3. d. interphase consists of the g1, s, and g2 phases

4. c. metaphase

5. a. chromosomes are duplicated before cell division so that each new daughter cell has a complete set
