Inherited Traits
What are inherited traits?
Characteristics passed from parents to offspring through genes.
What is an acquired behavior?
A behavior learned through experience or interaction with the environment.
What is natural selection?
The process where organisms better adapted to their environment tend to survive and produce more offspring.
What is selective breeding?
The process of breeding plants or animals for specific traits.
What is evolution?
The change in the inherited characteristics of biological populations over successive generations.
Give an example of an inherited trait in humans.
Eye color or hair type.
Provide an example of an acquired behavior in animals.
A dog learning to sit on command.
Name a factor that can influence natural selection.
Environmental changes, predators, or availability of resources.
Name a common example of selective breeding in animals.
Breeding dogs for specific traits, like size or temperament.
What is a common misconception about evolution?
That it happens in one individual's lifetime.
What is the difference between inherited traits and acquired traits?
Inherited traits are genetic, while acquired traits are influenced by the environment.
How do acquired behaviors differ from inherited behaviors?
Acquired behaviors are learned, while inherited behaviors are instinctive.
Who is known as the father of natural selection?
Charles Darwin.
How does selective breeding differ from natural selection?
Selective breeding is human-directed, while natural selection occurs naturally.
What evidence supports the theory of evolution?
Fossils, genetic similarities, and observed changes in species.
How can selective breeding highlight inherited traits?
By selectively breeding for specific inherited traits, these traits become more pronounced in future generations.
Can acquired behaviors influence a species' evolution?
Yes, they can affect survival and reproduction rates.
How does natural selection lead to evolution?
Over time, traits that enhance survival become more common in the population, leading to changes in species.
What is a potential downside of selective breeding?
It can lead to reduced genetic diversity.
What is the role of mutations in evolution?
Mutations can create new traits that may be beneficial for survival.
Name a genetic disorder that is inherited.
Cystic fibrosis or sickle cell anemia.
Can you name a situation where an acquired behavior helps an animal survive?
Birds learning to recognize predators or find food.
Give an example of natural selection in action.
The development of antibiotic resistance in bacteria.
Describe a plant that has been affected by selective breeding.
Corn, which has been bred for larger size and higher yield.
How long does evolution typically take?
Evolution can take millions of years, but changes can also occur more quickly under certain conditions.
