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:

Magnitude of genetic drift is dependent on two factor such as frequency of allele as well as population size, which of the following is correct?
a) decrease population size leads to increasing the magnitude of genetic drift
b) maximum magnitude are seeing whenever p=q
c) maximum magnitude are seeing whenever p>q
d) increasing population size also increasing the magnitude of genetic drift

geneticist is working with a new bacteriophage called phage Y3 that infects E. coli. He has isolated eight mutant phages that fail to produce plaques when grown on E. coli strain K. To determine whether these mutations occur at the same functional gene, he simultaneously infects E. coli K cells with paired combinations of the mutants and looks to see whether plaques are formed. He obtains the following results. (A plussign means that plaques were formed on E. coli K; a minussign means that no plaques were formed on E. coli K.)
How many cistron belong to these mutation?
