A variant from the wild type, often designated with a lowercase letter (e.g., 'd' for dwarf).

Individuals with identical alleles for a specific trait on homologous chromosomes (e.g., AA or aa).

Individuals with different alleles for a specific trait on homologous chromosomes (e.g., Aa).

A plant that consistently produces the same offspring after self-pollination because of homozygous genes.

A cross between two individuals focusing on one single character trait, involving one gene pair (e.g., flower color).

A cross involving two pairs of genes, each affecting a different characteristic. For example, crossing plants with yellow round seeds and green wrinkled seeds.

The observable characteristics of an organism, such as color, height, or shape. It's what you can see.

The genetic makeup of an individual, represented by the combination of alleles for a specific trait. It's the underlying code.

During gamete formation, alleles for a trait separate from each other, ensuring each gamete receives only one allele from each pair.

The second filial generation, resulting from the self-fertilization or cross-fertilization of individuals from the F1 generation.

Contamination of different plant lines due to physical mixing during cultivation.

Genetic material containing different versions of a gene, making it difficult to predict inheritance patterns.

Mendel carefully documented the shortcomings of previous research on inheritance, allowing him to avoid their mistakes.

Mendel's strong background in mathematics allowed him to understand and analyze the segregation of traits in the offspring.

The separation of different traits during inheritance, observed by Mendel in pea plants.

Mendel selected easily distinguishable traits in pea plants, simplifying the observation of inheritance patterns.

Traits that show distinct categories, allowing for easy classification of individuals.

A structure within cells that carries genetic material, composed of DNA.

A segment of DNA that codes for a specific trait or characteristic.

Different forms of the same gene located at the same locus on homologous chromosomes, influencing the same characteristic. Each individual inherits two alleles for a trait, but multiple alleles can exist within a population.

The most common and functional form of a gene; it's often dominant to other alleles.

Multiple alleles are different versions of the SAME gene, influencing the same characteristic. Different genes, on the other hand, are located at different loci and may control unrelated traits.

An individual inherits two alleles for any given trait, one from each parent.

A classic example of multiple alleles. Humans have three alleles: A, B, and O, which determine blood type.

Proteins found in the blood that are part of the immune system and bind specifically to antigens.

Substances, often located on the surface of cells, that trigger an immune response and bind to specific antibodies.

Human red blood cells (RBCs) contain two primary antigens: A and B.

The presence or absence of A and B antigens determines the four blood types: A, B, AB, and O.
