Mutations induced by UV.
The answer is option A.
They have a defect of their "curly gene," that's on the second chromosome. Having curled wings is a dominant mutation, this means that only one copy of the gene must be altered to supply the disorder. In reality, if both copies are mutated, the flies do not continue to exist.
Geneticists have lengthily counseled that mutations in insect pigment genes reason for modifications in the fly's brain because these pigments are crafted from dopamine, a chemical messenger that acts in the brain.
Thru those early experiments, he located that every one of the white-eyed flies being produced was a man, there were no white-eyed women in any respect. Inheritance of the white-eye trait might have a basis within the chromosomes, greater, in particular, the sex chromosomes.

Answer:
Global warming poses a series of challenges to agriculture, such as:
Changing rain patterns, where there are long periods of heavy rain followed by longer dry periods. That change can occur even within small regions.
The same to temperature patterns, drying up water reservoirs and actually burning up crops that, at that time, need a more humid environment.
Those changes can also trigger greater numbers of floods, droughts, and other effects on crops that livestock depend upon. That change in crops, in turn, may bring new insects that otherwise would not thrive there, decimating entire lands that were naturally protected from, those pests before.
Those are just some of the examples of climate change effects on agriculture and, therefore, to men.
