Genetic Variation
What is genetic variation?
Differences in DNA among individuals within a species.
What is a mutation?
A change in the DNA sequence that can affect genes or chromosomes.
What is one cause of spontaneous mutations?
Random errors during DNA replication.
What is a neutral mutation?
A mutation that does not affect the organism's traits.
I strike fear into the hearts of villains, yet I wear no mask. I wield a weapon but have no superpowers. My wings spread hope in Gotham. Who am I?
Batman
Name one source of genetic variation.
Mutations, sexual reproduction, or genetic recombination.
What is a point mutation?
A change in a single nucleotide.
Name an environmental factor that can lead to mutations.
UV rays or certain chemicals.
Give an example of a beneficial mutation.
Mutations that increase resistance to diseases.
I live in the shadows, yet I bring light, with green at my side, I soar through the night. Who am I?
The Green Lantern
How does sexual reproduction contribute to genetic variation?
It combines DNA from two parents, creating unique offspring.
Name one type of chromosomal mutation.
Duplications, inversions, deletions, or translocations.
What role do biological agents play in mutations?
Viruses can sometimes cause genetic mutations.
What is a harmful mutation?
A mutation that negatively impacts an organism's health or survival.
Fast as a blink, quicker than light, I’m the scarlet hero who’s always in flight. Who am I?
The Flash
What is genetic recombination?
The process during meiosis where chromosomes exchange sections, leading to new trait combinations.
What are spontaneous mutations?
Random errors that occur during DNA replication.
How can radiation affect DNA?
It can cause changes or damage to the DNA structure, leading to mutations.
What are silent mutations?
Mutations that occur in non-coding DNA or do not change the amino acid sequence, having no effect.
I may be a clown, but I’m no fool. My laugh is infamous, my games are cruel. Who am I?
The Joker
Why is genetic variation important for species?
It leads to diversity, which is essential for adaptation and survival.
How can environmental factors cause mutations?
Exposure to radiation, chemicals, or biological agents like viruses can alter DNA.
Explain how chemical exposure can lead to mutations.
Certain chemicals can alter DNA, resulting in mutations.
Why are some mutations considered beneficial to evolution?
They enhance survival or reproductive success, aiding adaptation to environments.
I wear no mask, yet I’m known by many faces. I bring fear not with fists but with words. My touch brings out darkness, and I prey on the mind. I am hunted by the Bat, yet I live in the shadows of Gotham’s psyche. Who am I?
