We Found a Bunch of New Eye Color Genes | SciShow News

The video discusses advancements in organoid research, focusing on lab-grown mini-organs that mimic real organs. It highlights the creation of tear gland organoids that can 'cry' and their potential in studying diseases like Sjogren's syndrome. The video also explores the complexity of eye color genetics, revealing that eye color is influenced by multiple genes, contrary to the simple Mendelian trait model. Recent studies identified 50 new genes related to eye color, offering insights into pigmentation conditions and challenging previous genetic assumptions.

What are organoids primarily used for in scientific research?

• To develop new types of food

• To replace damaged organs in patients

• To create artificial intelligence systems

• To model and study the functions of real organs

Which neurotransmitter was used to induce tear production in tear gland organoids?

• Dopamine

• Serotonin

• Noradrenaline

• Acetylcholine

How many new genes related to eye color were identified in the recent study?

• 25

• 100

• 10

• 50

What was the traditional view of eye color inheritance?

• It is influenced by environmental factors

• It is a Mendelian trait governed by one or a few genes

• It is determined by diet

• It is random and unpredictable

What did the research reveal about the genetic influence on eye color across different ancestries?

• Eye color is not influenced by genetics

• Different genes influence eye color in different ancestries

• The same genes influence eye color in both European and Asian ancestries

• Eye color is solely determined by environmental factors
