WorksheetsLesson 5- Artificial Selection
Total questions: 24
Worksheet time: 16mins
A farmer buys a bull that grows really large very quickly to breed with his cows so their offspring can produce more meat. Which type of artificial selection is this?
Selective breeding
Inbreeding
Hybridization
What is an example of artificial selection?
Letting dogs choose their own mate
Letting plants pollinate on their own
Crossing a labrador and a poodle to create a labradoodle
1. Artificial selection has been a big factor in the evolution of:
Dogs
Panda bears
Snakes
Jellyfish
The following is a similarity between artificial selection and natural selection
Takes hundreds of years
Humans determine traits
Nature determines traits
Offspring are produced
Which statement is true comparing natural selection and artificial selection?
In natural selection, traits benefit humans and in artificial selection, the traits benefit the species
In natural selection, traits benefit the species and in artificial selection, the traits benefit humans
In natural and artificial selection, the process takes hundreds of years to occur
In natural and artificial selection, nature determines what traits will be passed down to offspring.
Artificial selection takes
a shorter period of time than natural selection
a longer period of time than natural selection
the same amount of time as natural selection
Artificial selection is also known as
natural selection
selective hearing
genetic manipulation
selective breeding
What is this an example of?
natural selection
artificial selection
What is this an example of?
natural selection
artificial selection
What is recombinant DNA
DNA from 2 different organisms combined
DNA from 2 different ribosomes
DNA that is separated out from a vector
Which are pros (benefits) of GMOs?
Inexpensive medicines for people (example: insulin)
More nutritious crops
higher crop yield means more money for farmers
All answers are correct
Humans with genetic diseases can have a gene inserted into their body using a virus. This is called:
Gene therapy
Cloning
DNA fingerprinting
1. The process of choosing parent organisms for desired characteristics is called
natural selection
Artificial selection
random selection
genetic manipulation
Evidence shows that the wolf is the ancestor to all of the breeds of dogs shown below. How did this variation arise in a relatively short period of time?
Selective/Artificial Breeding
Natural selection
When selective breeding food crops what might a farmer select for? (Select all that apply.)
The plant the produced the most grain
The plant the produced the largest sized grain
The plant that was the most disease resistant
The plant that was the smallest
The smelliest plant
What are the benefits to gene therapy?
Bad genes increase
A bad gene can be replaced with a healthy gene
What is the changing of the cells of a tomato plant in order to keep insects away while it grows on the vine, therefore increasing its chances of making it to market?
Genetic Therapy
genetic modification
Natural Selection
Survival of the Fittest
What is transplanting normal genes into defective cells via infusion?
Genetic Modification
Gene Therapy
Natural Selection
Selective Breeding
What is the transplantation of normal genes into cells in place of missing or defective ones in order to correct genetic disorders?
Gene Therapy
Genetic Modification
Natural Selection
Survival of the Fittest
