What is one advantage of sexual reproduction?
The offspring are identical to the parents.
The offspring are resistant to viruses.
The offspring are born live, rather than from eggs.

How does the DNA of the offspring formed from asexual reproduction compare to the parent?
none of the DNA is transferred to the offspring
half of the DNA is transferred to the offspring
the DNA of the offspring is identical to the DNA of the parent
none of these are correct

Selective breeding is...
a process to create an organism with desired traits from parents with those desired traits to benefit humans
natural method of producing offspring with desired traits
creating a new species
making organisms reproduce during times of stress
An example of selective breeding is
a dog breeder mating 2 dogs to make more dogs
a farmer grows bees to pollinate the plants on his farm
a person pollinates 2 white rose plants to only create white roses
What is a good argument for genetically modifying animals?
Produce more meat
Figure out how to make Spiderman
Modifying your kids to make them more awesome
New genes are needed to create new species
An inherited trait that helps those organisms that have it to survive
niche
structure
characteristic
adaptation
This is any variation that makes an organism better suited to its environment.
Evolution
Graduation
Species
Adaptation
What is natural selection?
When reproduction occurs and mutations happen.
When a offspring has the traits from its parents.
When an organism is able to camoflauge in its environment.
the process whereby organisms that are better adapted to their environment tend to survive and reproduce more offspring.
In a cold environment what would be some adaptive traits? Sellect all that apply.
thick blubber
thick fur
thin fur
strong muscles
What is a mutation?
When animals have extra legs
When a frog has 3 eyes
When genes or DNA have been alterd or changed
When RNA is upside down
What is an adaptive trait?
A genetic trait that helps an organism to maximize its survival and reproduction ability
A trait that makes an animal strong
a trait that makes an animal weak
a poisonus plant
1. The process of choosing parent organisms for desired characteristics is called
