For each of the following scenarios, identify what microevolutionary process is occurring (be as specific as possible) and also indicate what effect (if any) it will have on the genetic diversity of the population 1 Some birds with shorter beaks enter into a population of birds with much longer beaks, resulting in several offspring with in-between sized beaks in the next generation. 2 Male Gorillas fight each other for the rite to be the male head of the troop (-silverback). The silverback will then have exclusive mating rights with all the mature females in the troop. 3 For years the tuberculosis bacterium was successfully treated with penicillin but one year a patient contracts the disease and the penicillin treatment is no longer effective as the bacteria have suddenly become resistant to this antibiotic. 4 A species of butterfly has a solid coloration pattern that ranges from light to dark green. One population living in an area with a distinct type of vegetation that is medium green in color has many more medium green colored butterflies than either light or dark green butterflies and you notice that it is much easier to detect either light or dark green colored butterflies than medium green colored butterflies.

Step Three: The Dry Season Data During the dry season, the trees lose their leaves. The primates now eat the ants off of the brown tree branches. 1. In this environment, which allele frequency (brown or green) do you hypothesize will increase over time? Table 3: Number of ants collected during the dry season Generation of ants Brown ants Generation 1 Generation 2 Generation 3 Generation 4 65 90 125 150 Green ants 170 150 Explorations Lab and Activities Manual 120 100 Total ants 235 240 CC BY-NC 245 Calculate the frequency of the brown allele and of the green allele in each of the generations. We assume that each ant is a homozygote. Round to the nearest thousandths. 250 To calculate allele frequencies: Within each generation, 1. Calculate the number of brown alleles by multiplying the number of brown ants (from Table 3) by 2. Calculate the number of green alleles by multiplying the number of green ants (from Table 3) by 2. Write in Table 4. 2. Calculate the total number of alleles by…

A wild population of pea plants has two alleles for flower colour in its gene pool. A dominant allele (P) specifies purple flowers; a recessive allele (p) specifies white flowers. If the frequency of allele P is 0.75, what is the expected frequency of p

Consider a gene with two alleles, C and M. The table below describes fitness for different genotypes in two populations.   Fitness   CC CM MM Population 1 1.0 1.0 0.6 Population 2 0.9 0.9 1.0  Assume that both populations begin with frequencies of 0.5 for each allele, population size is infinite, and there is no migration between populations. Which of the following statements is true based on the information you have on these populations?
