In this version of the simulation (500 population size; 500 carrying capacity), all fish are equally likely (though not 100% likely) to survive and reproduce. There are no mutations, nor are there any entering or leaving the population. When they reproduce, they choose a mate from the pool at random and produce ten offspring by chance with the probability of the offspring’s genotypes determined by the punnett square. What caused the allele frequencies to change and vary in the trials? (ex attached).
The MN blood group is of interest to population geneticists because (a) people with genotype MN cannot receive blood transfusions from either MM or NN people (b) the MM, MN, and NN genotype frequencies can be observed directly and compared with calculated expected frequencies (c) the M allele is dominant to the N allele (d) people with the MN genotype exhibit frequency-dependent selection (e) people with the MN genotype exhibit heterozygote advantage
If all copies of a given locus have the same allele throughout the population, the allele frequency is (a) 0 (b) 0.1 (c) 0.5 (d) 1.0 (e) 10.0
Huntington’s Disease A population of people has a gene that determines whether they will developHuntington’s disease. The gene has two alleles, ”N” for normal allele and ”h” for the Huntington’s allele.According to the Hardy-Weinberg equilibrium, the frequency of the ”h” allele in the population is 0.005. Part AWhat is the frequency of the ”N” allele in the population?Part BWhat is the expected proportion of people in the population who are carriers of the Huntington’s disease?Part CWhat is the expected proportion of people in the population who are non-carriers of the Huntington’s disease?Part DWhat is the expected proportion of people in the population who will develop Huntington’s disease?
if an allele for a gene is fixed the frequency cannot change, which of the following statements is true? All members of the population are heterozygous There are at least 3 phenotypes related to that gene represented in the population The population is more genetically diverse because that allele is fixed None of the above
The figure below shows data on the frequency of the A1 allele at a locus over time (i.e., generations) in 10 populations of flour beetles evolving independently of one another. The populations were all maintained in the lab under the same conditions.

Under idealized Hardy-Weinberg conditions, which of the following is FALSE? [1] O mutation rates will increase with each generation O no new alleles would be added to the population's gene pool O there will be no change in alelle frequencies in a population over time O the population is so large that random affects don't change allele frequencies all of these are true
Which of the following mathematical formulas is correct in how to calculate allele frequencies in a population? Take the number of one type of allele and subtract it from the number of the other type of allele Take the total number of alleles and divide it by the total number of both types of alleles Take the total number of alleles and divide it by the number of one type of allele Take the number of one type of allele and divide it by the total number of alleles
A sample of 600 individuals from a population is examined for the presence of the HindIII polymorphism in an autsomal Sca gene. There are two alleles of Sca gene, A and a. The results are 14 individuals are AA, 212 are Aa, 374 are aa. Please answer the following questions accordingly? How many alleles are present in the gene pool in the sample population fort he Sca gene? What are the genotype frequencies? What are the frequencies of A and a alleles? What are the expected numbers of the three genotypes, assuming random matings.
Why can all the allele and genotype frequencies in a population be determined based on the number of recessive individuals in the population? Recessive individuals are represented by only q2 and dominant are represented by both 2pq and p2 Recessive individuals are represented by only p2 and dominant are represented by both 2pq and q2 Recessive individuals are represented by q and dominant are represented by p Recessive individuals are rare and thus less in numbers making it easier to calculate
