Genetic inheritance

Fun Genetics: Heterozygous vs. Homozygous and More!

Genetic variation and inheritance patterns explain the diversity within species, covering both heterozygous vs homozygous variation examples and inheritance mechanisms. The content explores phenotype ratios, types of variation, and key genetic terminology essential for understanding inheritance patterns.

  • Predicted vs actual phenotype ratios reasons vary between heterozygous and homozygous crosses
  • Continuous variation and polygenic inheritance demonstrate how multiple genes influence physical characteristics
  • Discrete variation shows distinct trait groupings controlled by single genes
  • Key genetic terms including alleles, phenotype, and genotype form the foundation of inheritance understanding
  • Different inheritance patterns explain how traits are passed from parents to offspring

I love this app so much [...] I recommend Knowunity to everyone!!! I went from a C to an A with it :D

Stefan S, iOS User

The application is very simple and well designed. So far I have found what I was looking for :D

SuSSan, iOS User

Love this App ❤️, I use it basically all the time whenever I'm studying

Understanding Variation and Inheritance

This comprehensive page explores fundamental concepts in genetics and inheritance, focusing on how characteristics are passed between generations and expressed in organisms.

Definition: Variation refers to the differences between individuals of the same species, resulting from random fertilization processes.

Example: Phenotype ratios in genetic crosses:

  • Heterozygous × Heterozygous: 3 dominant to 1 recessive
  • Heterozygous × Homozygous recessive: 1 dominant to 1 recessive

Vocabulary: Key genetic terms and their meanings:

  • Allele: Different forms of a gene
  • Dominant: Stronger allele capitallettercapital letter
  • Recessive: Weaker allele smalllettersmall letter
  • Gamete: Sex cell
  • Heterozygous: Individual with two different alleles
  • Homozygous: Individual with two identical alleles
  • Phenotype: Physical characteristics
  • Genotype: Set of genes possessed

Highlight: Two main types of variation:

  1. Continuous Variation: Shows a range of values height,weight,pulserateheight, weight, pulse rate
  2. Discrete Variation: Falls into distinct groups eyecolor,tonguerolling,bloodgroupeye color, tongue rolling, blood group

Definition: Inheritance patterns:

  • Single-gene inheritance: Characteristics controlled by one gene
  • Polygenic inheritance: Characteristics controlled by multiple genes

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.

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.

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

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🤍🤍

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!
