Genetic drift is the elimination of

Options

A. individuals
B. chromosomes
C. species
D. genes of some original characteristics of a species due to epidemics

Answer

**Step-by-Step Solution:**

1. **Understand the Concept of Genetic Drift:**
- Genetic drift refers to the random changes in the frequency of alleles (gene variants) in a population, particularly in small populations. It can lead to the elimination of certain alleles over time due to chance events.

2. **Analyze the Options:**
- **Option 1: Individual** - Genetic drift does not eliminate individual organisms; rather, it affects allele frequencies in a population.
- **Option 2: Chromosome** - While chromosomes carry genes, genetic drift specifically refers to changes in allele frequencies, not the elimination of entire chromosomes.
- **Option 3: Species** - Genetic drift does not eliminate entire species; it affects the genetic makeup of populations within a species.
- **Option 4: Gene of some original characteristic of species due to epidemics** - This option suggests that genetic drift can lead to the loss of certain genes, which aligns with the definition of genetic drift.

3. **Identify the Correct Answer:**
- Based on the analysis, the correct answer is **Option 4**: Gene of some original characteristic of species due to epidemics. This option accurately reflects how genetic drift can lead to the elimination of specific alleles or genes in a population.

**Final Answer:**
Genetic drift is the elimination of **gene of some original characteristic of species due to epidemics** (Option 4).
