Understanding Alleles in Genetics

What do genes primarily code for in organisms?

• Traits like eye color directly

• Specific proteins or RNA chains

• Environmental factors

• Mutations

In the frog example, what does the yellow allele of the eye color gene code for?

• Green eyes

• Blue eyes

• Yellow eyes

• Red eyes

What is a key factor that can influence an animal's traits besides genes?

• Exercise

• Social interactions

• Environmental factors

• Diet

How do new alleles typically come into existence?

• Through natural selection

• Via mutations

• By genetic engineering

• Through environmental changes

What term is used when an allele becomes dominant in an entire population?

• Mutation

• Adaptation

• Selection

• Fixation
