Character |
An observable heritable feature. |
|
Trait |
Any detectable variation in a genetic character. |
|
True-Breeding |
Referring to plants that produce offspring of the same variety when they self-pollinate. |
|
Hybridization |
In genetics, it is the mating, or cross-breeding, of two true-breeding varieties. |
|
P Generation |
The parent individuals from which offspring are derived in studies of inheritance; "P" stands for parental. |
|
F(1) Generation |
The first filial, or hybrid. offspring in a series of genetic crosses. |
|
F(2) Generation |
Offspring resulting from interbreeding of the hybrid F(1) Generation. |
|
Dominant Allele |
An allele that is fully expressed in the phenotype of a heterzygote. |
|
Recessive Allel |
An allele whose phenotypic effect is not observed in a heterozygote. |
|
Law of Segregation |
Mendel's first law, stating that each allele in a pair separates into a different gamete during gamete formation. |
|
Homozygous |
Having two identical alleles for a given gene. |
|
Heterozygous |
Having two different alleles for a given gene. |
|
Phenotype |
The physical and physiological traits of an organism, which are determined by its genetic make up. |
|
Genotype |
The genetic make up, or sets of allelesm |

Law of Independent Assortment |
Mendel's second law, stating that each pair of alleles segregates independently during gamete formation; applies when genes for two characters are located on different pairs of homologous chromosomes. |
