In Neurospora, the mutant stp exhibits erratic stop-and start growth. When a female of stp strain is crossed with a normal strain acting as a male, all progeny individuals' showed stp mutant phenotype. However, the reciprocal cross resulted in all normal progeny, individuals. These results can be explained on the basis of
A. Uniparental gene contribution
B. Nuclear inheritance with concept of dominance
C. Sex link character
D. stp mutation may be located in chloroplast DNA
The most appropriate statement or combination of the above statements for explaining the experimental results is:
