Heredity
What is heredity?
The passing of traits from parents to offspring.
What is a dominant trait?
A trait that can appear and covers another
What is an instinctive behavior?
A behavior an animal is born knowing how to do.
What is variation?
Differences in traits among individuals of the same species.
A baby bird has feathers like its parents. Is this inherited or learned?
Inherited
What is an inherited trait?
A characteristic passed from parents to offspring through genes.
What is a recessive trait?
A trait that generally appears when an organism inherits two recessive alleles.
What is a learned behavior?
A behavior developed through experience or practice
What is an adaptation?
An inherited characteristic that helps an organism survive or reproduce in its environment.
A lion cub learns hunting skills by watching its mother. What type of behavior is this?
Learned behavior
What are genes?
Instructions in DNA that help determine inherited traits.
Can an organism carry a recessive allele without showing the recessive trait?
Dominant trait
A spider spins a web without being taught. What type of behavior is this?
Instinctive behavior.
Why do polar bears have thick fur?
It helps keep them warm in cold environments.
Why do brothers and sisters sometimes look different?
They can inherit different combinations of genes from their parents.
Why might a puppy look similar to both of its parents?
It inherits genetic information from both parents.
True or False: A recessive trait can be passed from parents to offspring even if the parents do not show the trait.
True
A dog learns to sit when its owner says 'sit.' What type of behavior is this?
Learned behavior
How does a cactus's waxy coating help it survive?
It reduces water loss in dry environments.
A rabbit's fur blends into its surroundings. What adaptation does this demonstrate?
Camouflage
Two plants have the same parents but different heights. How can this happen?
Offspring can inherit different combinations of genes, creating variation.
A baby animal gets one dominant gene version and one recessive gene version for a trait. Which trait will show?
The dominant trait
Why can learning to avoid a dangerous predator help an animal survive?
It helps the animal recognize danger and escape in the future.
Why might a bird with a longer beak survive better where food is deep inside flowers?
Its beak may help it reach food more easily, giving it a survival advantage.
Explain the difference between heredity and variation
Heredity passes traits from parents to offspring and variation describes differences among individuals
