1. Describe what is happening in figures 1-3. 1 2 o. Is the population of mice different in figure 3 than in figure 1? Explain why. : Living things that are well adapted to their environment survive and reproduce. Those that are not well adapted don't survive and reproduce. An adaptation is any characteristic that increases fitness, which is defined as the ability to survive and reproduce. What characteristic of the mice is an adaptation that increased their itness? 3.

C. Adaptation and Genetic Variation. The picture below represents four different species of finch. Study the picture and answer the questions that follow. 2 3 1. The finches have different beaks based on what they eat. Which do you think eats seeds? 2. Which do you think eats insects? 3. Which do you think eats leaves?. 4. Which do you think eats fruits? 5. Darwin theorized that all four of these finches evolved from one ancestor. Why do you think their beaks evolved?

the area titled Genotype Relative Fitness. Notice that the default is for all three genotypes to be set at 1.0. This indicates that all three genotypes have the same effect on survival and reproduction. Change the Genotype Relative Fitness of the rr genotype to 0.6. This indicates that the rr genotype (white phenotype) has a strong disadvantage over the other type genotypes in terms of survival and reproduction. Start the simulation and let it run for 200 generations. http://virtualbiologylab.org/ModelsHTML5/PopGenFishbowl/PopGenFishbowl.html When you started the simulation, your initial alleles frequencies were: R = 0.5 r = 0.5 What are your allele frequencies after 200 generations of strong selection?
Select all that apply. Beetles from two geographically isolated populations are captured and brought to the lab. When an adult male from one population and an adult female from the other population are placed together, they mate, and the female lay eggs a couple of days later. The eggs hatch, the beetles develop into adults but are sterile. Which of the following are true? This is an example of post-zygotic reproductive isolation. O Sexual selection is likely responsible. O This is an example of pre-zygotic reproductive isolation. O Dobzhansky-Muller genetic incompatibility is likely responsible. Question 3 Choose all that apply. Which of the following are true of adaptive radiations? OAdaptive radiations involve relatively rapid speciation. The evolution of the Hawaiian silverswords is an example of an adaptive radiation. OAdaptive radiations can occur when an ancestral species colonizes a new arca and adapts to multiple open niches. Question 4 What are the three major steps of…
I expect for genetically identical animals that have been reared in similar conditions to have a smaller SD for any parameter that I decide to measure compared to genetically diverse animals that have been grown in a variety of natural environments.
rolution on.com/player Stages of natural selection What is the order of stages in natural selection? Genetic variation exists between individuals of a population. Individuals compete with each other for food, water and mates, and to avoid predators. Individuals with adaptive phenotypes compete better and are more likely to survive and reproduce, at the expense of... ..individuals with less adaptive phenotypes and fewer competitive characteristics, which die or reproduce less. Genes for adaptive char acteristics are more likely to be inherited. The number of individuals with the adaptive phenotype increases. oboardworks 18 of 29 Chp
Lithobates clamitus. also know as the green frog and bronze frog can range in in skin color from pure to brown to pure green and a mixture of both. As their habitats change frogs with a mixture of both colors have a higher fitness as they are better able to hide from predators. 1. If the change in the distribution of this trait is the result of natural selection, name the mode of selection (ie: Balancing, Disruptive, etc...) 2. If a small group of male frogs end up joining this population from a different population of frogs, which process of selection describes the movement of alleles present in the male frog? 3. The process you named in “c” ________ the genetic variation in the population that the male frog joined? (increase, decrease, or stay the same?)
True or False. Write whether the statement is true or false. 1. Microevolution is visible when the bigger beaks of finches are expressed more over time because it can help their species survive better. 2. It is common for populations to satisfy the Hardy-Weinberg Equilibrium. 3. Natural selection can alter the traits of organisms in a population and create new ones according to what will improve individuals' survival and reproduction. 4. Artificial selection is a new technology of the 21st century that produce change in populations 5. When an athlete acquires muscle strength, muscle density and agility, he can passi t on his offspring.

Pollen from trees is blown far, far away to a completely separate group of trees and pollinates their flowers, with genetic producing trees characteristics of each population. 3. A certain type of plant can produce blue or yellow flowers. During a fire, many yellow flowers are destroyed, and now since blue is the dominant allele, the plant reproduces plants that only produce | blue flowers. 10 |Page 4.

ACTIVITY 9.2: Essay. Directions: Read the situation and identify the points of Darwin’s natural selection. There are 2 types of worms: worms that eat at night (nocturnal) and worms that eat during the day (diurnal). The birds eat during the day and seem to be eating ONLY the diurnal worms. The nocturnal worms are in their burrows during this time. Each spring when the worms reproduce, they have about 500 babies but only 100 of tthese 500 ever become old enough to reproduce.A.
