Key Concepts

Monohybrid Cross

A monohybrid cross is a genetic cross between two individuals that differ in a single trait, typically involving one pair of contrasting traits. This type of cross helps to determine the inheritance pattern of a specific gene, allowing for the observation of dominant and recessive alleles. The classic example is crossing a homozygous dominant plant with a homozygous recessive plant to analyze the offspring's genotype and phenotype ratios.

Test Cross

A test cross is a breeding experiment used to determine the genotype of an individual exhibiting a dominant phenotype. This is achieved by crossing the individual with a homozygous recessive individual for the trait in question. The resulting offspring's phenotypes reveal whether the dominant individual is homozygous or heterozygous, providing insight into the genetic makeup of the parent.

Genetic Inheritance

Genetic inheritance refers to the process by which traits and characteristics are passed from parents to offspring through genes. Understanding inheritance patterns, such as those observed in monohybrid and test crosses, is crucial for predicting the likelihood of certain traits appearing in future generations. This concept is foundational in genetics, influencing fields such as breeding, medicine, and evolutionary biology.
