type of genetic variation	example
gene flow
sexual reproduction

the wind carries seeds from a flower population in one field to a flower population in another field.
a chicken with black feathers mates with a rooster with white feathers and has an offspring with black and white feathers.
a change in the dna of bacteria results in some of the bacteria being resistant to antibiotics.

Explanation:

• Mutation: A mutation is a change in the DNA sequence. The example "A change in the DNA of bacteria results in some of the bacteria being resistant to antibiotics" describes a DNA change (mutation) leading to a new trait (antibiotic resistance).
• Gene flow: Gene flow is the transfer of genetic material from one population to another. The example "The wind carries seeds from a flower population in one field to a flower population in another field" involves the movement of genetic material (via seeds) between two populations, so this is gene flow.
• Sexual reproduction: Sexual reproduction involves the combination of genetic material from two parents. The example "A chicken with black feathers mates with a rooster with white feathers and has an offspring with black and white feathers" shows genetic combination from two parents (chicken and rooster) leading to a new genetic combination in the offspring, which is sexual reproduction.

Answer:

• Mutation: A change in the DNA of bacteria results in some of the bacteria being resistant to antibiotics.
• Gene flow: The wind carries seeds from a flower population in one field to a flower population in another field.
• Sexual reproduction: A chicken with black feathers mates with a rooster with white feathers and has an offspring with black and white feathers.
