Understanding the Retina and Color Blindness

The video explains the structure of the eye, focusing on the retina's photoreceptors: rods and cones. It details how these cells help perceive light and color. The video then discusses color blindness, its genetic basis, and why it is more common in men. The X chromosome's role in color blindness is highlighted, explaining how genetic differences between men and women affect the condition's prevalence.

What are the two types of photoreceptors in the retina?

• Cylinders and spheres

• Cones and spheres

• Rods and cylinders

• Rods and cones

What is the role of rods in the retina?

• Detecting color

• Detecting movement

• Detecting light and dark

• Detecting sound

Which type of cone is responsible for detecting blue light?

• Blue cone

• Yellow cone

• Green cone

• Red cone

How many types of cones are there in the human eye?

• Five

• Four

• Three

• Two

What is the common term for color deficiencies?

• Color distortion

• Color enhancement

• Color saturation

• Color blindness

What happens if there is an issue with the red cone?

• The world appears more red

• The world appears more blue

• The world appears more green

• The world appears less red

Which gender is more commonly affected by color blindness?

• Women

• Men

• Neither

• Both equally

Why are men more likely to be color blind than women?

• Men have two X chromosomes

• Men have only one X chromosome

• Men have fewer rods

• Men have more cones

What genetic component is responsible for color blindness?

• Y chromosome

• W chromosome

• Z chromosome

• X chromosome

What must happen for a woman to be color blind?

• Two broken genes on the Y chromosomes

• One broken gene on the X chromosome

• Two broken genes on the X chromosomes

• One broken gene on the Y chromosome
