Genetics: Multiple Alleles

David, Ava, and Sophia are studying genetics. They come across a concept where traits are controlled by more than two alleles. What is the term used for such traits?

• Polygenic traits

• Multiple alleles traits

• Complex traits

• Variety traits

Rohan, Liam, and Noah are discussing about traits controlled by multiple alleles in their biology class. Rohan says that an example of a trait controlled by multiple alleles is:

• Different types of blood among humans

• Different hair color in humans

• Different leaf shapes in plants

• Different wing sizes in birds

How are new alleles formed in a population?

• Through natural selection

• Through mutation in a gene

• Through environmental factors

• Through genetic recombination

Anika, Aria, and Grace are studying for a biology test. They come across a question about the term used for the different types of blood among humans. What is the term they are looking for?

• Blood variety

• Blood heterogeneity

• Blood diversity

• Blood polymorphism

Scarlett, Ethan, and Anika are studying genetics and they come across a concept of traits controlled by multiple alleles. Which of the following examples they discussed is an example of a trait controlled by multiple alleles?

• Different beak shapes in birds observed by Scarlett

• Different tail lengths in dogs noticed by Ethan

• Different fur patterns in cats that Anika has

• Different eye color among fruit flies they studied in class
