It's not that hard to open a hospital in another world, right?

Chapter 1207 Spell Power, Cyclonus Research
"Observe the division process of Escherichia coli after staining... Ah, the Escherichia coli is dead...Is it because I poured too much dye..."

"Re-staining...very good, this time the E. coli is alive and dividing, but it's not stained clearly, I can't see it clearly..."

"Dye it again..."

Gretel stumbled and tossed day after day under the microscope, day after day.From E. coli to the tip of the onion, from the tip of the onion to the frog egg.

After proving the role of the nucleus, proving the existence of chromosomes, proving that chromosomes and genes have a parallel relationship (hey, the technique of promoting growth is really useful, and the technique of cleaning is really useful in peeling frog eggs), finally, it is time to prove that chromosomes are gene carriers It's time!

"That...so I need a fruit fly with white eyes..."

Gretel held his chin, staring at the bottle after bottle of fruit flies the elves found, entangled and dazed.

After he said the condition of "like to eat fruit", the elves did quickly find a batch of fruit flies for him, but these little things all had red eyes!

Red eyes red eyes red eyes red eyes...

"Gretel, do you want to go to sleep for a while?" Ashe Moonsong floated past him, looking at his thick dark circles with concern:
"Your eyes are red..."

"Ah, red...I don't want red eyes, I want white eyes..."

Gretel answered dreamily.In fact, fruit flies have many other traits, such as long wings, small wings, such as setae on the legs.

But Gretel couldn't remember whether the wings were sex-linked inheritance, and it was too painful to use a magnifying glass to look at the fly's leg hair. It would be better to have white eyes to make the researchers happy...

"What's wrong with you, Gretel?!"

Gretel shook his head vigorously, raised his hand, and snapped his fingers.The water making technique was activated, and a puff of clear water poured down his head, drenching him completely.He blinked, shook his hair, and finally felt a little more awake:
"I have a solution!"

He jumped up, grabbed a small vial of fruit flies, his fingertips shone slightly, and threw a paralysis spell over.

The fruit flies in the bottle fell to pieces. Gretel turned the bottle over and poured out the paralyzed (anesthetized) fruit flies. Holding the remaining eggs and larvae in the bottle, he began to mutter:
"Give me white eyes...give me white eyes...give me white eyes..."

While reciting, stretch out your mental power, trying to cover every fruit fly egg and every larva.The power of nature in the palm of the hand is spinning, hazy, trying to convey to these little guys, passing on their own will:
Hey, show some face, red eyes grow into white eyes?
The light green force of nature was thrown into the bottle, as if thrown into a bottomless pit, and was completely absorbed by the fruit fly eggs and larvae.

Soon, the fly eggs begin to hatch, and the larvae begin to molt, grow, molt again, and pupate.The whole process is like a quick shot, a blink is a change, and a blink is a change.

As for the white eyes...

"Uh, the little guys don't give face..."

Gretel smiled helplessly, changed the bottle, and prepared to continue the experiment.Ashe Moonsong watched the whole process, and hurriedly interjected:
"Grete, do you want them to grow white eyes? Then don't change the bottle, just keep spawning! One round is not enough for two rounds, two rounds is not enough for three rounds, it can always be done! If you change a batch now, it is equivalent to starting from scratch, and they will be fine. I don't recognize you anymore!"

what?
And this trick?
Gretel didn't do much work for birthing, so at this time, it was natural to absorb the advanced experience of his predecessors.Holding the bottle, he patiently waited, waited, waited...

"Hey, why didn't new fruit flies come out?"

"Eggs and larvae are all spawned by you, of course there are no new ones!"

"Then they..."

Gretel wanted to say, "Why don't you mate?" He glanced at Ashe Moonsong, and felt that he should pay attention to his wording in front of young single women.After a pause, the tongue turned a bend:

"...Why don't you lay eggs?"

"Maybe it was just born, a little confused?" Ashe Moonsong glanced at it, bent her fingers, and tapped her fingertips on the glass bottle wall.

A misty cyclone passed by, and soon, those fruit flies were seen buzzing and gathering together in pairs.

... Sister, your hand is much better than those necromancers who are frantically flipping through the "Pink Book"!
Gretel looked at him with admiration.Ashe Moonsong raised her chin with pride on her face:

"See? Learn more, we forest guards, this little spell to help animals is very useful!"

Yes, yes, yes, yes, yes... I just don't know, elf forest guard, it's okay to throw birth spells on animals...

Grete nodded, watching the fruit flies fly down one by one to lay their eggs, paralyzing and transferring them.Holding a new batch of fly eggs, continue to communicate, continue to supply the power of nature, and continue to give birth...

After doing this again and again, a batch of white-eyed fruit flies were finally born.As if he had found a precious treasure, Gretel transferred them one by one to a bottle, waiting for them to mature and mate naturally.

Then, this batch of mating finished laying eggs, and the new fruit flies that hatched...

Eyes are red again...

The traits are unstable, the mutations cannot be inherited, or, they just fade the color of the eyes during the growth process?All in all, we must continue to work hard to supply the power of nature, continue to modify, and spread our hands.

Gretel inhaled deeply, exhaled deeply.Catch this new batch of fruit flies and cast a spell to make them mate and lay eggs.During this process, it began to continuously supply the power of nature and communicate with them:
"Give me a child with white eyes... a child with white eyes... a child who can pass on white eyes from generation to generation..."

After a few generations of tossing, the blind cat met a dead mouse, and finally tossed out a fruit fly with white eyes—and it was successfully passed on to the second generation.

Gretel was overjoyed, watching them inherit two generations, and finally took these fruit flies to mate with the red-eyed fruit flies:
"Red, white, red, white... Aww! The numbers are wrong! Isn't the gene induced by this spell invisible?!"

Crying and chirping, this batch of fruit flies was placed on the side and let them grow on their own.Take another bottle of Drosophila larvae and start induction again:
"Bring me children with faded eyes...children with faded eyes...from generation to generation, children with faded eyes..."

Alas, what kind of luck did Morgan, the white-eyed king, get a fruit fly that happened to be white-eyed, invisible, and sex-linked?
"Okay, this time, the number of white eyes and red eyes of the newly hatched fruit flies is finally right...began to observe its chromosomes...take the larval salivary glands..."

Even so, Gretel also knew that with the help of spells, his research was already on the fast track.First of all, targeted mutagenesis is possible, so there is no need to wait for luck from the sky;

Secondly, it can be spawned by magic, instead of breeding one generation, and waiting seven or eight days, and worrying about the fruit flies not being able to feed;
Finally, magic can be used to prompt the fruit flies to mate, so there is no need to worry about the white-eyed fruit fly failing in its career and dying in the middle of the road.

Of course, the convenience of spells can also be reflected in other aspects:
"Cleansing! Fat removal from salivary glands!"

"Ah, it's a little crooked, half of the salivary glands are gone..."
