The Work of Gregor Mendel

Meet the monk who changed science forever! Gregor Mendel wasn't your typical religious figure - he was obsessed with understanding how traits pass from parents to offspring.

Working in the 1800s, Mendel spent years carefully breeding plants and recording his observations. When he published his findings in 1866, he had no idea he was creating the foundation of modern genetics.

Did you know? Mendel's work was so ahead of its time that other scientists didn't understand its importance until decades later!

Mendel's Pea Plant Experiments

Mendel chose pea plants for his experiments because they were perfect for studying inheritance. He focused on height tall plants have the dominant allele 'T' whilst short plants have two recessive alleles 'tt'.

His first experiment was brilliant in its simplicity. He bred pure-bred tall plants (TT) with short plants (tt). Every single offspring appeared tall because they all inherited at least one dominant T allele.

But here's where it gets interesting! When Mendel bred these offspring together, something unexpected happened. Three-quarters looked tall, but one-quarter were short - the recessive trait had mysteriously reappeared.

Key insight Traits don't blend together like paint colours - they stay separate and can pop up in later generations!

Mendel's Revolutionary Findings

From his pea plant experiments, Mendel discovered three game-changing principles that still guide genetics today. First, he realised that characteristics are determined by 'hereditary units' - what we now call genes.

Second, these hereditary units pass down unchanged from parents to children. You don't get a mixture of your parents' traits; you get specific units from each parent that remain distinct.

Third, hereditary units are either dominant or recessive. Dominant traits show up whenever they're present, but recessive traits only appear when you inherit them from both parents. This explains why some family traits can skip generations!

Think about it You might have your grandmother's eye colour even though your parents have different coloured eyes - that's Mendel's principles in action!

After Mendel Building on the Foundation

Mendel's work was just the beginning of an incredible scientific journey. In the late 1800s, scientists began discovering chromosomes and started to see connections between these structures and inheritance.

The early 1900s brought a major breakthrough when researchers recognised the similarities between Mendel's 'hereditary units' and newly discovered genes. Suddenly, his pea plant experiments made perfect sense!

By 1953, scientists had unlocked the structure of DNA, finally understanding the molecular basis of genes. What started with a monk and his pea plants had evolved into our modern understanding of genetics and heredity.

Amazing fact It took nearly 90 years for science to fully catch up with Mendel's brilliant insights!

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Samantha Klich

Android user

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

Anna

iOS user

I think it’s very much worth it and you’ll end up using it a lot once you get the hang of it and even after looking at others notes you can still ask your Artificial intelligence buddy the question and ask to simplify it if you still don’t get it!!! In the end I think it’s worth it 😊👍 ⚠️Also DID I MENTION ITS FREEE YOU DON’T HAVE TO PAY FOR ANYTHING AND STILL GET YOUR GRADES IN PERFECTLY❗️❗️⚠️

Knowunity is the BEST app I’ve used in a minute. This is not an ai review or anything this is genuinely coming from a 7th grade student (I know 2011 im young) but dude this app is a 10/10 i have maintained a 3.8 gpa and have plenty of time for gaming. I love it and my mom is just happy I got good grades

Brad T

Not only did it help me find the answer but it also showed me alternative ways to solve it. I was horrible in math and science but now I have an a in both subjects. Thanks for the help🤍🤍

David K

The app's just great! All I have to do is enter the topic in the search bar and I get the response real fast. I don't have to watch 10 YouTube videos to understand something, so I'm saving my time. Highly recommended!

In school I was really bad at maths but thanks to the app, I am doing better now. I am so grateful that you made the app.

I found this app a couple years ago and it has only gotten better since then. I really love it because it can help with written questions and photo questions. Also, it can find study guides that other people have made as well as flashcard sets and practice tests. The free version is also amazing for students who might not be able to afford it. Would 100% recommend

Best app if you're in Highschool or Junior high. I have been using this app for 2 school years and it's the best, it's good if you don't have anyone to help you with school work.😋🩷🎀

THE QUIZES AND FLASHCARDS ARE SO USEFUL AND I LOVE THE SCHOOLGPT. IT ALSO IS LITREALLY LIKE CHATGPT BUT SMARTER!! HELPED ME WITH MY MASCARA PROBLEMS TOO!! AS WELL AS MY REAL SUBJECTS ! DUHHH 😍😁😲🤑💗✨🎀😮

This app is phenomenal down to the correct info and the various topics you can study! I greatly recommend it for people who struggle with procrastination and those who need homework help. It has been perfectly accurate for world 1 history as far as I’ve seen! Geometry too!
