Which of the following statements is NOT TRUE about natural selection?
Offspring of individuals that are better adapted will make up larger population in the next generation.
Natural selection directs evolution by preserving traits acquired during an individual's lifetime.
Natural selection acts to preserve favorable traits and eliminate unfavourable traits.
Natural selection leads to evolution.
"Survival of The Smartest"
"Survival of The Fastest"
"Survival of The Biggest"
"Survival of The Fittest"
individuals with alleles for an extreme type are more likely to survive and reproduce
stabilizing selection
directional selection
disruptive selection
genetic drift
the selection pressure favors the extreme phenotypes, dividing the population into 2 distinct groups
directional selection
stabilizing selection
geographic selection
disruptive selection
Individuals with intermediate traits are more likely to survive and reproduce
stabilizing selection
directional selection
adaptive radiation
disruptive selection
Tall kelp have a distinct advantage over shorter kelp in receiving needed sunlight in their ocean environment
directional selection
disruptive selection
stabilizing selection
artificial selection
Aspen trees that are over 25 m tend to blow over in high winds; aspen that are under 15 m do not get enough sun.
directional selection
stabilizing selection
disruptive selection
artificial selection
Light-colored oysters would blend into the rocks in the shallows, and the darkest would blend better into the shadows. The ones in the intermediate range make them easier prey.
directional selection
stabilizing selection
disruptive selection
artificial selection
The process of choosing parental organisms for desired characteristics is called
natural selection
artificial selection
random selection
genetic manipulation
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 is also known as
natural selection
selective hearing
genetic manipulation
selective breeding
Teosinte, gave rise to the modern maize. It was through a slow genetic selection that our ancestral farmers modified these weeds into the food crops that we grow nowadays. This is an example of:
Artificial selection
Genetic engineering
Natural Selection
Evolution
Problems with animals that are selectively bred include:
Being healthier and more resistant to disease.
Producing more meat.
Being more likely to suffer from genetic disease.
Being more genetically diverse.
What is inbreeding
When two closely related animals are bred together
When two not related animals are bred together
When animals are allowed to chose their own mates
When humans choose which animals will mate together
True or False. Artificial selection is used to create fruits, vegetables, and animals with desired phenotype.
True
False
