What are the predators of rock pocket mice?
The Rock Pocket Mouse lives in a desert ecosystem: The Valley of Fire in New Mexico, United States. The mouse’s main predators are Owls, Hawks, Snakes, Coyotes, and Foxes.
What is the genetic difference between light and dark colored mice?
The difference between dark and light mice boils down to a difference of four chemical letters in a gene called MC1R. Because the gene controls the amount of dark pigment in a mouse’s hair follicles, a mouse with these mutations grows dark fur, which gives it an advantage on a dark background.
What did Dr Knockman find when he studied the genes of the dark and light-colored rock mouse?
Knockman find when he studied the genes of the dark and light-colored rock mouse? They could change their color to be more helpful in their environment. 18. What was the purpose of the Human Genome Project?
How many years would it take for the mouse population to become 95% dark if there was a 5% competitive advantage to having a dark coat color?
1,000 years
How do you get a population of dark-colored mice?
The dark-colored mice arose in the population at location A by random mutation. The phenotype did not become more common because it did not afford a selective advantage to the mice. o Base your prediction on trends in the data you have organized.
Why do light fur mice survive less often on dark rocks compared to dark fur mice?
Answer: Light-fur mice survive less often on dark rocks because they are easily seen by predators while dark-fur mice are harder to see. The same situation applies to dark-fur mice on light rocks.
What biological processes could influence the fur color of the rock pocket mice that live on light colored rocks vs dark rocks?
The biological processes that could influence the fur color of the rock pockert mice that live on light-colored vs. dark rocks are by natural selection becasue the dark is on the dark rocks and the light mouses are on the light rocks.
Why does color affect a pocket mouse’s ability to survive?
An ideal coat colour like that of a rock pocket mouse will help it to camouflage with rocks and hence help it to escape from predators. As a result, the mouse will be able to live and reproduce which depicts there overall fitness for the environment.
Why does the pocket mice color influence its fitness?
Explain why a rock pocket mouse color influences its overall fitness. So, on the tan sand more light colored mice will survive because they blend in and on the dark lava rock more dark colored mice will survive and the allele for dark fur will be passed on to their offspring.
Which organisms are most likely to survive?
According to Charles Darwin’s theory of evolution by natural selection, organisms that possess heritable traits that enable them to better adapt to their environment compared with other members of their species will be more likely to survive, reproduce, and pass more of their genes on to the next generation.
Is the population of mice different in Figure C than in Figure B?
Answer: As the mice crossing the road one of its predator (eagle) attack them and the predator successfully grab one of its pray (mice). Yes. the population of figure C is less compared to the population of figure B.
Which mouse is the fittest?
TAN MOUSE
Why does the predator select white mice over black mice for food?
Explanation: In the daytime, the black mice are much easier to spot, and predators eat more black mice. The white mice stand out at night. This means owls eat more white mice at night.
What is a major advantage of natural selection?
Through this process of natural selection, favorable traits are transmitted through generations. Natural selection can lead to speciation, where one species gives rise to a new and distinctly different species. It is one of the processes that drives evolution and helps to explain the diversity of life on Earth.
What do you think the population of mice on the white sand would look like after many generations?
8) What do you think would happen to this population of mice after many generations on the gray sand? About half of the mice (54%) would have gray fur. Almost all of the mice would have gray fur. There would be equal numbers of mice with white fur, gray fur and black fur.
Why do you think is the reason why the female mouse with gray fur has the most babies?
What do you think is the reason why the female mouse with gray fur had the most babies? Because the number of babies it produces is 7 more the black fur mice also gray fur mice have a longer death span of 6 years.
How is this deer mouse well adapted for life in the forest?
How is this deer mouse well adapted for life in the forest? Notice how its dark coloring would allow the deer mouse to easily hide from predators on the darkened forest floor. On the other hand, deer mice that live in the nearby Sand Hills are a lighter, sand-like color.
What is evolution by natural selection quizlet?
Evolution by natural occurs when individuals with certain alleles produce the most surviving offspring in a population. An adaption is a genetically based trait that increases an individuals ability to produce offspring in a particular environment.
What is the evidence that supports the theory of evolution by natural selection quizlet?
How does this pattern support the theory of evolution by natural selection? It is evidence that species can change over time. Related species inherited homologous traits from a common ancestor.
What is a major difference between evolution and natural selection?
Evolution is a gradual change in the inherited traits of a population over many generations. Natural selection is a mechanism where the members of a population best suited to their environment have the best chance of surviving to pass on their genes.
What is the role of natural selection in evolution quizlet?
what is the role of natural selection in the process of evolution? Natural selection leads to evolutionary change when individuals with certain characteristics have a greater survival or reproductive rate than other individuals in a population and pass on these inheritable genetic characteristics to their offspring.
What are four main principles to the theory of natural selection?
There are four principles at work in evolution—variation, inheritance, selection and time. These are considered the components of the evolutionary mechanism of natural selection.
Which Lion would Biologists consider the fittest?
Tyrone
