Textbook Question
Chapter 56.1, Problem 3CC
WHAT IF? → Imagine two populations of a fish species, one in the Mediterranean Sea and one in the Caribbean Sea. Now imagine two scenarios: (1) The populations breed separately, and (2) adults of both populations migrate yearly to the North Atlantic to interbreed. Which scenario would result in a greater loss of genetic diversity if the Mediterranean population were harvested to extinction? Explain your answer.

Q2.16. When heavily armored marine sticklebacks have invaded freshwater lakes where there are no predatory fish,
their populations have evolved lighter body armor. Given what you've learned about evolution, which of the
following explanations for why this happens is most plausible?
O Young sticklebacks only grow heavy armor when they see predatory fish in their environment.
O When sticklebacks don't use their armor, it shrinks. Then they pass lighter armor to their offspring.
Concentrated pollutants in freshwater lakes disrupt the sticklebacks' ability to grow armor.
O Heavily armored fish grow more slowly and breed later, making armor disadvantageous in these lakes.
Choose True for yes and False for no, for each of the statements
1) The distribution of the two species-C populations cannot be explained by two totally independent dispersal events by the common ancestor species of A and B.
True or false
2) B must share a more recent common ancestor with C1 than it does with C2.
True or false

Say a rare species of butterfly has two versions of color called blue (B) and white (b). You want to repopulate
the species for the wild, but also breed and sell them. You find the blue butterflies are the most appealing to
customers and want to breed them for the maximum profit. Blue is BB and Bb, while white is bb. State the
percent change of getting blue butterflies from the following crosses:
5. Blue (BB) and White (bb)
6. Blue (Bb) and White (bb)
7. Blue (BB) and Blue (BB)
8. Blue (Bb) and Blue (Bb)
Name:
9. White (bb) and White (bb)

- Try to outline a scenario explaining the evolution of the three species shown in panel g. Use migration, mutation, genetic drift, selection, reproductive isolation, gene flow, extinction, and many generations in your scenario. Based on your scenario, what are the components that are necessary in a population in order for it to split or diverge into two new daughter species from a single ancestor (the parent species)?arrow_forward2) In a particular island, the environment is semi-arid. There is a lizard population with a lot of variation for color. Normally, the light sandy color and golden colored lizard flourished because they escaped predation, while others were barely surviving. However, in recent years, a lot of rain has brought about a lot of vegetation. Which variation of lizard will now flourish in the area? * A) white B) Brown C) Green D) Redarrow_forwardIn which situation will populations experience gene flow?

- Q6.9. Consider the following hypothetical scenario: An ancestral species of duck had a varied diet that included aquatic plants and terrestrial plants and insects. These ducks spent time on both land and water. Individuals of this species varied in the amount of webbing in their feet, with some individuals having more webbing and some having less. As many years went by, the environment changed such that the aquatic food sources were much more plentiful than those on land. Many generations later, almost all ducks had more webbing on their feet. How is this best explained? Ducks with less webbing worked harder than ducks with more webbing to eat aquatic plants. The more they used their feet, the more webbed their feet became, so they got enough food to survive and reproduce. Due to chance mutations, all the ducks' feet in the next generation had more webbing. They were therefore able to eat aquatic plants and get enough food to survive and reproduce. Ducks with more webbing were better…arrow_forwardQ7. Ten years later, the researchers return to Niijima Island and they notice that there are members of the same land snail species, but they have a pink shell. What are the two most likely explanations for this shell color new to Niiima? Choose the 2 best answers a. A random mutation in a snail that resulted in a pink shell. b. The bottleneck effect occurred among the snail population on Nijima c. Genetic Drift d. Disruptive selection over many generations e. Some snail eggs from a neighboring island that has pink snails were transported to Nijima on the feet of migratory ducks.arrow_forwardr-selected species display all of the following traits, except: A) Population size is density dependent B They have large numbers of offspring Most offspring are short-lived D) There is little parental carearrow_forward
- Plz answer shortly. You are a conservation biologist working on a captive breeding program for black-footed ferrets. You have the budget to establish either two populations of 100 ferrets each, or 10 populations of 20 ferrets each. Which approach do you think is most likely to succeed, and why?arrow_forward. As coral reef communities continue to experience ocean acidification and bleaching, a population of gobbie fish and their allelic variability has rapidly decreased, this is an example of a) founder effect b) mutation c) natural selection d) gene flow e) bottleneck effectarrow_forwardScenario 1In the 1960s, a population of squirrels (Sciurus carolensis) was being studied in Alabama and the coat color of the squirrels was found to range from the more common gray color (dominant) to the less common red color (recessive). When they sampled an area, they found 536 gray squirrels and 64 red squirrels. Assume that the population is at Hardy-Weinberg equilibrium. 3A.

Redrawn from Vignieri, Larson, & Hockstra (2010). In a 2010 paper, Vignieri et al.

When they collected the models, they recorded the number of tooth and bill imprints made by visually oriented predators like birds and mammals. a) Identify the independent and dependent variables of this experiement. b) Using data from the graph, discuss the fitness consequences for mice that are mismatched for their environment. c) Considering only the results of this one experiment, rank your level of confidence in the interpretation that mouse fur color has fitness consequences (use a scale of 1-5, where 5 is absolutely convinced, 3 is neutral, and 1 is unconvinced).
