Why was it important in the studies of Beadle and Tatum that Neurospora is haploid?
A) Because it is easier to grow haploid molds in the laboratory.
B) Because haploid molds have simpler nutritional requirements than do diploid molds.
C) Because a mutation that arises is not masked by a normal allele on a homologous chromosome.
D) Because haploid Neurospora will always mutate.
E) Because diploid Neurospora will always mutate.
