Term | Definition |
Character | An observable heritable feature that may vary among individuals. |
Trait | One of two or more detectable variants in a genetic character. |
P Generation | The true-breeding (homozygous) parent individuals from which F1 hybrid offspring are derived in studies of inheritance. |
F1 Generation | The first filial, hybrid (heterozygous) offspring arising from a parental (P generation) cross. |
F2 Generation | The offspring resulting from interbreeding (or self-pollination) of the hybrid F1 generation. |
Allele | Any of the alternative versions of a gene that may produce distinguishable phenotypic effects. |
Dominant Allele | An allele that is fully expressed in the phenotype of a heterozygote. |
Recessive Allele | An allele whose phenotypic effect is not observed in a heterozygote. |
Law of Segregation | Mendel’s first law, stating that the two alleles in a pair segregate (separate from each other) into different gametes during gamete formation. |
Homozygous | Having two identical alleles for a given gene. |
Heterozygous | Having two different alleles for a given gene. |
Phenotype | The observable physical and physiological traits of an organism. |
Genotype | The genetic makeup, or set of alleles, of an organism. |
Monohybrid Cross | A cross between two organisms that are heterozygous for the character being followed (or the self-pollination of a heterozygous plant). |
Dihybrid Cross | A cross between two organisms that are each heterozygous for both of the characters being followed (or the self-pollination of a plant that is heterozygous for both characters). |
Law of Independent Assortment | Mendel’s second law, stating that each pair of alleles segregates, or assorts, independently of each other pair during gamete formation. |
Pedigree | A diagram of a family tree with conventional symbols, showing the occurrence of heritable characters in parents and offspring over multiple generations. |
