What is the main concern of the client in the detective scenario?

• The baby's hair color

• The baby's eye color

• The baby's skin color

• The baby's height

What is the primary pigment responsible for skin color?

• Chlorophyll

• Carotene

• Melanin

• Hemoglobin

Where in the skin is melanin primarily produced?

• Dermis

• Subcutaneous layer

• Epidermis

• Hypodermis

How many genetic variants affecting pigmentation have been identified?

• More than 200

• At least 100

• Around 50

• Less than 10

What are the two types of melanin mentioned?

• Eumelanin and Chlorophyll

• Chlorophyll and Carotene

• Carotene and Hemoglobin

• Eumelanin and Pheomelanin

What evolutionary factor influenced the variation in skin pigmentation?

• Dietary habits

• UV radiation exposure

• Climate change

• Migration patterns

What role does melanin play in relation to UV radiation?

• Increases UV absorption

• Enhances vitamin D production

• Protects DNA from UV damage

• Decreases UV absorption

Why can't skin color alone determine paternity?

• Skin color is not inherited

• Skin color changes with age

• Skin color is a complex trait

• Skin color is influenced by diet

What is required to confirm paternity?

• A melanin test

• A genetic variant test

• A paternity test

• A skin color analysis

What does the client ultimately need to resolve his concern?

• A detailed genetic analysis

• A paternity test

• A skin pigmentation chart

• A consultation with a dermatologist
