Review questions BSC3052 Conservation genetics 1 Explain Heteroygosity Polymorphism De ne Given an example 2 Explain the difference between expected and observed heterozygosity Discuss why the sample size matters this was not discussed in class directly but should be obvious from the random genetic drift discussion 3 Calculate the number of individuals that are heterozygote in the 6th generation The gene frequency zallele frequency in generation 1 are pA 025 and there are only two alleles A and oz 4 Two color morphs alleles and B of the leopard frog Rana pipiens The allele B is dominant heterozygotes B look like BB The B allele forces to show no spots the allele homozygote shovvs spots The study was done in Minnesota and investigated if there were differences in allele frequency between animals found dead compared to animals caught alive Condition Phenotype Genotype Observed Number Living 53 834 Dead BB B 39 1050 ll Calculate the allele frequency of p and pB in the living and the dead population Are they different Because of the dominance of one allele you cannot simply use the formula I gave in class What do you need to assume to solve this 5 You are monitoring a population of endangered turtles and find that allele frequences differ from HardyWeinberg expectations What could you conclude about your population as a result of this finding and how might it inform your conservation decisions 6 What is genetic drift and why does it matter What are the population or genetic parameters that influence the effects of drift in a population Page 1 Review questions BSC3052 Population Viability analysis Count based PVA H Explain the the main formula that we used on class to describe population growth and shrinkage to Produce a graph with 3 example 77population growth curves 1 shrinking7 2 constant7 3 growning7 label everything on the graph OJ Calculate the growth rate from this data Records of cticious sightings of Elaphe guttata in Southwood in year 2000 to 2006 447 437 427 407 397 39 0 Show a graph with time on the x axis and the growth rate A on the y axis Calculate A for the years 2001 up to 2006 0 Calculate the average growth rate over all years and its standard deviation 0 Make a prognosis about the population size in year 2007 and 2008 Discuss the fate of this population based on the growth rate and the standard deviation of the growth rate estimate 4 describe and discuss the assumptions of count based PVAs Structured PVA H Explain the the main formula for a stage structured PVA to The cticious sightings of Elaphe guttata in Southwood was used to calculate transition rates from Juveniles to adults 02557 Staying with the adult class 0457 having 2 eggs per adult per year 0 Sketch a stage graph7 label all parts and ll in the transition rates Assume that the transition rates are correct and that the snakes mature within a year Show the projection matrix7 calculate the number ofjuveniles and adults in year 2001 when we use the values of 2000 where we found 30 juveniles and 14 adults What is the growth rate between year 2000 and 20017 compare this with the count based method above 0 Show a graph with time on the x axis and the growth rate A on the y axis Calculate A for the years 2001 up to 2006 using the start condition 30 juveniles7 14 adults How would you calculate the stable growth rate Does your graph give a hint what the stable growth rate could be 0 make prognosis about the population size in year 2007 and 2008 3 describe and discuss the assumptions of the structured PVA Page 1
