please solve all parts as they are the same question but MCQ's thank you! Which of the following statements about devil facial tumour disease (DFTD) is true? All the cancerous cells in the infected Tasmanian devils are clones of one another. DFTD is transmitted by respiratory droplets exchanged between individuals in close proximity to one another. It has been detected in other marsupials in Australia. It is a viral pathogen that spreads among Tasmanian devils. It mainly affects immature individuals in the Tasmanian devil population.Suppose there are three isolated populations of a beetle. Population A has had a constant population size of 10,000 . Population B has had a constant population size of 1,000 . Population C has had a constant population size of 100 . We would most expect to see an increase in the frequency of deleterious alleles in population due to B; purifying selection A; genetic drift C; gene flow A; purifying selection C. genetic drift.
