1. The process of choosing parent organisms for desired characteristics is called
natural selection
Artificial selection
random selection
genetic manipulation
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
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 is also known as
natural selection
selective hearing
genetic manipulation
selective breeding
All artificial selection or "selective breeding" is good
True
False
Artificial Selection decreases diversity which is bad because
organisms with same traits will refuse to reproduce with each other
organisms with all the same traits are susceptible to extinction.
organisms with the same traits will be very aggressive
organisms with same traits collectively get smarter and will some day rule the world
As scientists have developed more productive crop varieties, farmers have switched from growing many traditional varieties to new high-yield varieties. For example, in Peru, the Indians once grew 500 native varieties of potatoes. That number has been reduced to about twenty major potato varieties, worldwide. Why is it potentially dangerous to reduce the number of crop species in potatoes?
it reduces the variety of crops available for human diets
it requires a larger investment than small farmers can make
it makes the overall crop more susceptible to pests or disease
crossing two parents that have identical or similar sets of alleles
inbreeding
cloning
hybridization
crossing of two genetically different parents for getting the best traits from both parents
inbreeding
cloning
hybridization
What is this an example of?
natural selection
artificial selection
What is this an example of?
natural selection
artificial selection
The following is a similarity between artificial selection and natural selection
Takes hundreds of years
Humans determine traits
Nature determines traits
Offspring are produced
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
Humans often use methods of artificial selection, such as selective breeding, to produce horses with specific traits.
Which statement best describes how selective breeding helps horse breeders produce the most desirable traits for racing?
Selective breeding produces horses with a higher rate of survival due to an increase in the genetic diversity of the horse offspring.
Selective breeding helps breeders control which traits are passed on by producing horse offspring that only have the desired traits.
Selective breeding uses two horse parents with the desired traits to increase the chances of passing the desired traits on to offspring.
Selective breeding uses two horse parents with unknown traits to produce offspring with genetic variations and different traits.
What is a goal of selective breeding?
I. To increase the value of species to humans
II. To produce species that resist disease
III. To produce species with specific traits
I and II
II and III
I and III
I, II, and III
Which of the following statements is true regarding selective breeding?
Selective breeding only works in plants.
Selective breeding only works in animals.
Selective breeding produces changes in genes.
Selective Breeding is exactly like natural selection
