The common edible frog of Europe is a hybrid between two species, Rana lessonae and Rana ridibunda. The hybrids were first described in 1758 and have a wide distribution, from France across central Europe to Russia. Both male and female hybrids exist, but when they mate among themselves, they are rarely successful in producing offspring. What can you infer from this information?

What will be the effect light in GA biosynthesis?
a) Light basically activates the GA 3β-hydroxylase which
adds a hydroxyl group (OH) to carbon 3 of GA20 and convert GA20 to GA1
b) light-induced increase in the transcription of the gene
for GA3ox, which converts GA20 to GA1
c) light-induced increase in the transcription of the gene
for GA2ox, which converts GA20 to
GA29
d) light-induced decreases the transcription of the gene for GA3ox, which converts GA20 to GA1
