Solved by a verified expert:1Autopolyploidy Allopolyploidy & Hardy-Weinberg Equilibrium Exercises1.A. A new plant species B forms by autopolyploidy from species A, which has achromosome number of 2n = 10. Assuming that the cell’s chromosome number wasdoubled from the diploid number (2n) to a tetraploid number (4n), how manychromosomes would species B have? ____________B. To explain the process that generated the tetraploid cell of problem #1implement the following guidelinesdraw a series of diagrams that represent a cell going through the process ofcell divisionlabel each one of these cells with the number of chromosomes it containsindicate where a meiotic error took place. 22.If species A in problem # 1 were to hybridize by allopolyploidy with species C (2n =14) and produce a new, fertile species, D, how many chromosomes would species Dhave? Use the following guidelines to answer the question:Draw a series of diagrams to describe the process of allopoliploidy. Eachdiagram should depict a cell going through the meiotic processlabel each cell with the number of chromosomes it containsindicate where a meiotic error(s) took place.3. In a Hardy-Weinberg population with two alleles, B and b, that are in equilibrium, thefrequency of the allele b is 0.4. What is the percentage of the population that ishomozygous for this allele? Explain your answer. ______ 34. In a Hardy-Weinberg population with two alleles, B and b, that are in equilibrium, thefrequency of allele b is 0.1. What is the percentage of the population that is heterozygousfor this allele? Explain your answer. ______5. Assuming that cystic fibrosis is a disorder in Hardy-Weinberg Equilibrium and that thefrequency of individuals born with cystic fibrosis in a ficticious country is approximately2/1000, calculate the frequency of carriers for the disorder. Note that cystic fibrosis is adisorder that results from homozygosity at a recessive allele.
