Genetic combinations | |
Monohybrid cross | is a mating between two individuals with different alleles at one genetic locus of interest. |
Dihybrid cross | a cross between two pure lines (varieties, strains) that differ in two observed traits. |
Non-Mendelian inheritance | is a general term that refers to any pattern of inheritance in which traits do not segregate in accordance with Mendel's laws. |
[Punnett Square] | a diagram that is used to predict an outcome of a particular cross or breeding experiment |
Gregor Mendel | was a German-speaking Moravian scientist and Augustinian friar who gained posthumous fame as the founder of the modern science of genetics |
Trait | a distinguishing quality or characteristic, typically one belonging to a person. |
Allele | alternative form that a single gene may have for a particular trait. |
Dominant | Mendel's name for a specific trait that appeared in the F1 generation |
Heterozygous | organism with two different alleles for a specific trait. |
Homozygous | organism with two of the same alleles for a specific trait. |
Recessive | Mendel's name for a specific trait hidden or masked in the F1 generation. |
Gene | functional unit that controls inherited trait expression that is passed on from one generation to another generation. |
Genotype | an organism's allele pairs. |
Genotypic ratio | Pattern of offspring distribution according to genotype (i.e. the genetic constitution determining the phenotype of an organism) |
Outcome | the way a thing turns out; a consequence. |
Cross | a method of hybridization or the hybrid so produced. |
