Chapter 1202: Spell Assistance, Research on Sturm und Drang
"Observe the division process of E. coli after staining... Yeah, the E. coli is dead... Could it be that I poured too much dye..."
"Re-staining... it's very good. This time the E. coli is alive and dividing, but it's not stained clearly and can't be seen clearly..."
"Dye it again..."
Grete stumbled and struggled under the microscope day after day, day after day. From E. coli to onion root tips, from onion root tips to frog eggs.
After proving the role of the cell nucleus, proving the existence of chromosomes, and proving that chromosomes have a parallel relationship with genes (hey, the growth-promoting technique is so useful, and the cleaning technique is so useful in peeling frog eggs), finally, it is time to prove that chromosomes are gene carriers
It's time!
"Well...so I need a fruit fly with white eyes..."
Gretel held his chin up and looked at the bottles of fruit flies that the elves had found, struggling and dazed.
After he said that he "likes to eat fruits", the elves did quickly find a group 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 take a nap?" Ash Moonsong floated past him and looked at his thick dark circles with concern:
"Your eyes are all red..."
"Ah, red... I don't want red eyes, I want white eyes..."
Grete replied in a dreamy voice. In fact, fruit flies have many other characteristics, such as long wings, small wings, and bristles on their legs.
But Gretel couldn't remember whether wings are sex-linked inheritance. It would be too painful to look at fly leg hairs with a magnifying glass. It would be better to have white eyes to make the researchers happy...
"Grete, what's wrong with you?!"
Grete shook his head vigorously, raised his hand, and snapped his fingers. The water-generating technique was activated, and a cloud of water poured down on his head, soaking him thoroughly. He blinked his eyes, shook his hair, and finally felt awake.
A little bit:
"I have an idea!"
He jumped up, grabbed a small bottle of fruit flies, his fingertips flashed slightly, and threw a paralysis spell at it.
The fruit flies in the bottle fell into pieces. Gretel poured the paralyzed fruit flies out, holding the remaining fly eggs and larvae in the bottle, and began to mutter something:
“Give me white eyes…Give me white eyes…Give me white eyes…”
While chanting, he stretched out his mental power, trying to cover every fruit fly egg and every larvae. The natural force in his palm rotated hazy, trying to convey his will to these little guys:
Hey, give me some face, can your red eyes grow into white eyes?
The green power of nature is thrown into the bottle as if it were thrown into a bottomless pit, where it is 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 form pupae. The walls of the pupae tear, and the emerging adults spread their wings and fly out. The whole process is like a fast-moving camera, changing in the blink of an eye.
A change occurs in the blink of an eye.
As for the white eyes...
"Well, the little guys don't give you face..."
Grete smiled helplessly, changed a bottle, and prepared to continue the experiment. Ash Moonsong watched the whole process and quickly interrupted:
"Grete, are you going to make them grow white eyes? Then don't change the bottle and continue to breed! One round won't work, two rounds won't work, two rounds won't work three rounds, it can always be done! If you change a batch now, it will be like starting from scratch, they will
I don’t recognize you anymore!”
ah?
Is there any other trick?
Grete had not done much work to promote the direction. At this time, it was natural to absorb the advanced experience of his predecessors. He held the bottle and waited patiently, waiting, waiting...
"Hey, why are there no new fruit flies coming out?"
"The eggs and larvae have been given birth to for you, so of course there are no new ones!"
"Then they..."
Gretel wanted to say "Why don't you mate?", then glanced at Ashe Yuege and felt that in front of young single women, you still need to pay attention to your wording. After a pause, he twisted his tongue:
"...Why don't you lay eggs?"
"Maybe he was just born and is a little confused?" Ashe Yuege took a look, raised his finger, and tapped the wall of the glass bottle with his fingertips.
A misty cyclone passed by, and soon I saw the fruit flies buzzing and gathering in pairs.
...Sister, your skills are much better than those necromancers who are busy flipping through the "Pink Book"!
Gretel was impressed. Ashe Yuege raised her chin, her face full of pride:
"See? Learn more, we forest guards, this little magic to help animals is very useful!"
Yes, yes, yes, yes... I just don’t know, the elf forest guard, why do you throw birthing spells to animals when you have nothing to do...
Gret nodded like a mince, watching the fruit flies fly down one by one to lay their eggs, paralyze them, and transfer them. Holding a new batch of fly eggs, he continued to communicate, continued to supply the power of nature, and continued to induce birth...
Repeatedly, a batch of white-eyed fruit flies finally spawned. Feeling like a treasure, Grete transferred them one by one to a bottle and waited for them to mature and mate naturally.
Then, after mating, this batch of eggs was laid, and the new fruit flies that hatched...
The eyes are red again...
The traits are unstable, mutations cannot be inherited, or they just faded in the eyes during the growth process? In short, we must continue to work hard to provide the power of nature, continue to modify, and let go.
Grete took a deep breath and exhaled deeply. He grabbed this new batch of fruit flies and cast a spell to make them mate and lay eggs. In the process, he began to continuously supply the power of nature and constantly 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 more generations, the blind cat encountered a dead mouse, and finally a fruit fly with white eyes was created - and it was successfully inherited to the second generation.
Grete was overjoyed and watched them pass on for two generations. Finally, he took these fruit flies and mated them with red-eyed fruit flies:
"Red, white, red, white... Ouch! The numbers are wrong! The gene induced by this spell is not invisible?!"
Crying, these fruit flies were placed aside and allowed to grow on their own. Take another bottle of fruit fly larvae and start the induction again:
"Give me children with faded eyes...children with faded eyes...children with faded eyes from generation to generation..."
Alas, Morgan, the Holy King of White Eyes, had some great luck and got a fruit fly that happened to have white eyes, a stealth factor, and a sex-linked inheritance!
"Okay, this time, the number of white eyes and red eyes of the newly hatched fruit fly is finally correct... Let's start observing its chromosomes... and take out the salivary glands of the larvae..."
Even so, Grete also knows that with the help of magic, his research has been on the fast track. First of all, he can use directed mutagenesis, so he doesn't have to wait for luck to fall from heaven;
Secondly, you can use magic to induce birth, instead of breeding one generation, waiting for seven or eight days, and worrying about not being able to feed the fruit flies;
Finally, you can use magic to induce fruit flies to mate, so you don't have to worry about the white-eyed fruit fly dying in the middle before it accomplishes its mission.
Of course, the convenience of spells can also be reflected in other aspects:
"Cleansing! Remove fat from salivary glands!"
"Ah, it's a little crooked, half of the salivary glands are gone..."
