Effective population size is the sum of all populations given. It is an ideal population size.
Mean population size is the ratio of effective population size to the number of generations.
Case | effective population size (add all given populations) | mean population size (effective population size/4) |
1 | 800 | 200 |
2 | 800 | 200 |
3 | 800 | 200 |
All the three cases will have same graph for effective and mean population size.
Part 2
Effective population size = 4(number of breeding males)(number of breeding females)/number of breeding males + number of breeding females
A. 4(50)(50)/50+50 = 10,000/100 = 100
B. 4(25)(75)/25+75 = 7500/100 = 75
C. 4(10)(90)/10+90 = 3200/100 = 32
Please rate.
Part 1 Consider the following three populations, each followed over 4 generations Population 1: N =...
Simulate the following population system: There are 100 mitochondrial DNA (mDNA) groups, each with 100 members, 50 male and 50 Write a program to simulate population growth, tracking the sizes of mDNA groups. To simplify, assume the members of the population marry at random and that they have children in distinct generations. For each generation, marry males and females picked at random, and assign each family 0, 1, 2, or 3 children, each randomly male or female, P(male) Plfemale).5, and...
#2 Consider the following model for the dynamics of a population of size N (measured as number of individuals x 10) over time (in months) that is subject to harvesting: The population grows according to a logistic equation in the absence of harvesting and h is a constant per a) Find all equilibria and determine the values of h for which each is stable or unstable. 4aestng andcnstant capita harvest rate. b) Construct the bifurcation plot: plot the equilibria from...
Independent random samples of n = 100 observations each are drawn from normal populations. The parameters of these populations are: • Population 1: μ1 = 300 and σ1 = 60; • Population 2: μ2 = 290 and σ2 = 80. (1) What is the probability that the mean of Population 1 is between 294 and 306? (2) How many samples should be included if we want the probability in Part (1) to be at least 95%? (3) What is the...
Pictured below (in scrambled order) are three histograms: One of them represents a population distribution. The other two are sampling distributions of x-bar; one for sample size n = 5, and one for sample size n = 30.

Thanks ahead of time!!! Problem 2: Modeling inseet population dynamies The use of arrays and matrix algebra are ideal for modeling population dynamics of organisms. If n) is computed from represents the number of organisms at time t, then the number at a later time, t+1, can be n(t+1) An(t). The array (vector, n) consists of the nurnber of females in each age class, and the array (matrix, A), called a Leslie matrix, is the survival- replacement matrix. Multiplying the...
Suppose we are interested in estimating the proportion p of a population that has a certain disease. As in Section 2.3 let y;-1 if person i has the disease, and yi 0 if person i does not have the disease. Then p . a Show, using the definition in (2.13), that 22 N- np If the population is large and the sampling fraction is small, so that write (2.26) in terms of the CV for a sample of size 1....
1-There is a population of individuals which are geographically isolated from other populations of their species. Their population mates randomly, has no net mutations in their genome, and is not subjected to natural selection pressures. However, their population is small, only 200 individuals. The gene for fur color in this population has two alleles in a dominant-recessive relationship, A and a. If allele A is currently at a frequency of 0.8 and allele a is at 0.2: i. What do...
In C++ Transient Population Populations are effected by the birth and death rate, as well as the number of people who move in and out each year. The birth rate is the percentage increase of the population due to births and the death rate is the percentage decrease of the population due to deaths. Write a program that displays the size of a population for any number of years. The program should ask for the following data: The starting size...
1. A researcher sets up 100 replicate population cages. Each is founded with 20 Drosophila melanogaster individuals, drawn from a population that is polymorphic for the L1 and L2alleles at a neutral pseudogene locus L. After many months the L1 allele is fixed in 11 of the cages and the L2 allele is fixed in 89 of the cages. Estimate the frequencies of the L1 and L2 alleles in the original population from which these cages were founded. 2. In...
