- In pea plants, the allele for tall stems is dominant over the allele for short stems.
- Alleles can be classified as dominant or recessive, affecting how traits are expressed.
- Each parent contributes one allele for each gene to their offspring.
Cultural Notes
In genetics, understanding alleles is essential for studying inheritance and variation in traits. The concept of alleles helps to explain why siblings can have different appearances despite having the same parents.
noun
Definition

Examples
- The color of a flower can be determined by the alleles that the plant inherits from its parents.
- Different alleles can lead to different physical characteristics in organisms.
- Scientists study alleles to understand genetic diversity within populations.
Cultural Notes
Alleles are a key concept in genetics and biology, and they play an important role in fields like agriculture, medicine, and evolutionary biology.
