Summary Introduction
Introduction:
The term “natural selection” was given and popularized by Charles Darwin. Simply, it is defined as “survival of the fittest”. It is the differential survival of organisms on the basis of their

Living things that are well adapted to their environment survive and reproduce. Those that are well adapted don't survive and reproducer. An adaption is any characteristics that increase fitness,which is defined as the ability to survive and reproduce. What characteristics of the mice is an adaptation that increased their fitness?
The following table shows the number of dogs for certain tail lengths in a population of dogs.
Tail Length
Number of Dogs
very short (less than 1 inch)
2
short (1–5 inches)
5
medium (5–10 inches)
15
long (10–15 inches)
5
very long (15–25 inches)
2
Based on this data, what type of trait is tail length in dogs
Pretend you are a scientist observing three different varieties of a single bird species that are part of the same population. In three to five sentences, describe what genetic variations exist in your population. Then, using reasoning skills and mock evidence from your observations, describe the impact these traits have on the birds’ relationships with their environment and predators.

- A difference in survival and reproduction among members of a population that vary in one or more traits is called ________.arrow_forwardWhich of the following is a form of a heritable trait that enhances an individual’s fitness? Adaptation Lineage Fitnessarrow_forwardThe process by which inherited characteristics of populations change over time is called_______ . Variability among individuals is the result of chance changes called_________ that occur in the hereditary molecule ________.arrow_forward
- Random chance has the greatest impact on the result of allelic frequencies when populations are: infinitely large. very small. shrinking. growing.arrow_forwardFirst part: determine heritability given below values. Second part: given the calculated values, which trait would you select for to increase the frequency of resistant snails in the fewest number of generations and why?”arrow_forwardThe graph below shows values for body size in parents and offspring. The data shown are consistent with which of the following situations. ANSWER CHOICES A. variation in body size is completely due to variation in the environment (heritability is 0) B. most of the variation in body size is due to variation in the environment but there is a small effect of genes (heritability is around 0.2) C. variation in body size is completely due to variation in genes (heritability is 1.0) D. most of the variation in body size is due to variation in genes but there is some effect of the environment (heritability is about 0.8)arrow_forward
- Shank color and plumage color are highly affected by the environment. True or Falsearrow_forwardThere are 653 individuals in a population 104 of the rabbits in the said population have recessive floppy ears and 549 rabbits have dominant short ears. Use this information to calculate The dominant allele frequency the recessive allele frequency the homozygous dominant frequency the heterozygous frequency and the homozygous recessive frequencyarrow_forwardThere are two traits in moths: light color and dark color. If a population has 60%of the moths with the light color, using Hardy-Weinberg, what can be predicted about the offspring of the population if no environmental factors are present? 40%of the offspring will be dark in color 40%of the offspring will be light in color 60%of the offspring will be dark in color 50%of the offspring will be each colorarrow_forward
- In a population of lynx, a census was taken in the spring and again a year later. In the spring, there were 400 baby lynx born, of which 300 had a normal speckled coat phenotype and 100 had a black phenotype. A year later, there were 200 speckled coat lynx and 50 black lynx that had survived to adulthood. Calculate the survivorship for each phenotype, and determine the relative fitnesses based on survivorship. What is the relative fitness of the black fur phenotype (wb)? a) 0.00 < w < 0.25 b) 0.25 < w < 0.50 c) 0.50 < w < 0.75 d) 0.75 < w < 1.00arrow_forwardBiologists classify specific forms of traits as good or bad. For example, long tails in cats could be classified as good and short tails as bad. true or false?arrow_forwardYou are studying two populations of rats—one in New York and theother in Florida. Adult New York rats seem to prefer Swiss cheese,whereas Florida rats seem to prefer cheddar. Design an experimentto determine the extent to which this behavior may be geneticallycontrolled versus environmentally influenced.arrow_forward
