Heterozygous
In genetics, the term "heterozygous" refers to the condition in which an organism has two different alleles for a particular gene. Each allele is a version of the gene that can lead to different traits. When an organism is heterozygous for a specific gene, it means that it has inherited different alleles for that gene from each parent.
Study Guide
- Definition: Heterozygous refers to the condition in which an organism has two different alleles for a particular gene.
- Alleles: Alleles are different versions of a gene that can lead to different traits.
- Inheritance: Heterozygous organisms inherit one allele from each parent, resulting in a combination of traits.
- Punnett Square: A Punnett square is a tool used to predict the possible genotypes of offspring based on the genotypes of the parents.
- Example: If a pea plant is heterozygous for flower color with one allele for purple flowers (P) and one allele for white flowers (p), it will exhibit the dominant purple flower trait.
Understanding the concept of heterozygous is essential in genetics and inheritance patterns. It plays a crucial role in determining the traits and characteristics of organisms based on their genetic makeup.

LIFE SCIENCE (NGSS)
From Molecules to Organisms: Structures and Processes
Students who demonstrate understanding can:
Construct an explanation based on evidence for how the structure of DNA determines the structure of proteins which carry out the essential functions of life through systems of specialized cells.
Heredity: Inheritance and Variation of Traits
Students who demonstrate understanding can:
Make and defend a claim based on evidence that inheritable genetic variations may result from: (1) new genetic combinations through meiosis, (2) viable errors occurring during replication, and/or (3) mutations caused by environmental factors.
