Which selection does the rock pocket mouse population exemplify? Explain your answer. Recall the 5 wats selection affects population variation.
How does this trait affect the survival of the mice in different environments? (0.5 point) 1 3. What specific trait did researchers study in this investigation? (0.5 point) The specific trait is the fur color of the mice. Examples of other fitness-related traits that researchers are currently investigating are resistance to the pesticide warfarin in rats, tolerance to heavy metals in plants, and antibiotic resistance in bacteria. The College Board is a mission-driven not-for-profit organization that connects students to college success and opportunity. In this type of research, investigators try to find the underlying gene or genes for a given adaptation.
#THE TINY ROCK POCKET MOUSE WEIGHS JUST 15 GRAMS PLUS#
Plus holds 15, while snub-nosed revolvers, like the Taurus Model 85 only. Investigating the adaptive value of different coat colors in rock pocket mice is an example of how scientists are attempting to connect genotype with phenotype for fitness-related traits. This little guy is much smaller than a snub nose revolver, but it doesnt offer. In particular, they were interested in understanding the forces that shape genetic variation in natural populations. Michael Nachman of the University of Arizona and his colleagues have spent many years researching the genetics of fur color in rock pocket mice. These areas of dark volcanic rock range in age from 1,000 to more than 1 million years old. You can find populations of rock pocket mice all over the Sonoran Desert in the southwestern United States. Rock pocket mice, however, have had an enormous impact on science. And at just 15 grams, this tiny mouse weighs about as much as a handful of paper clips. Here and there, however, separated by several kilometers of light-colored substrate, are patches of dark volcanic rocks that formed from cooling lava. And at just 15 grams, this tiny mouse weighs about as much as a handful of paper clips. Most of the desert landscape consists of light-colored sand and granite. Similarly, there are two major colors of substrate, or surface material, that make up the rocky desert floor.
Two varieties occur widely in the area-a light-colored variety and a dark-colored variety.
What's so special about this little mouse? Populations of rock pocket mice are found all over the Sonoran Desert in the southwestern United States. American Weigh Scales can supply digital scales to fit any weighing application, including custom digital scale applications of any kind. Its impact on science, however, has been enormous. A typical rock pocket mouse is 172 millimeters long from its nose to the end of its tail, which is shorter than an average pencil. INTRODUCTION The tiny rock pocket mouse weighs just 15 grams, about as much as a handful of paper clips.
