|
|
Inheritance/Heredity |
The transmission of traits from parents to their offspring. |
|
|
Allele |
An alternative form of a gene. |
|
|
Pure |
A gene that will always be seen or occur in the offspring. |
|
|
Strain |
Offspring that are pure for a specific trait. |
|
|
Dominant |
A gene that dominates the other gene. |
|
|
Recessive |
The gene that is controlled by the dominant gene. |
|
|
Genotype |
The genetic makeup of an organism. |
|
|
Phenotype |
The external appearance of an organism that is determined by the individual's genotype. |
|
|
Homozygous |
Referring to a gene pair in which the two alleles code for the same trait |
|
|
Heterozygous |
Referring to a gene pair in which the two alleles do not code for the same trait. |
|
|
Monohybrid |
A cross between individuals that involves one pair of contrasting traits. |
|
|
Dihybrid |
A cross between individuals that involves the pairing of contrasting traits. |
|
|
Test Cross |
The crossing of an individual of unknown genotype with a homozygous recessive individual to determine the unknown genotype. |
|
|
Hybrid |
An offspring resulting from the cross between parents of different species or sub-species. |
|
|
Genetics |
The field of biology devoted to understanding how traits are passed from parents to offspring. |
|
|
Punnett |
A model used to establish the probabilities of the results of a genetic cross. |
|
|
F1 Generation |
The offspring of cross pollinated P1 generation plants. |
|
|
P1 Generation |
A strain obtained through self-pollination. |
|
|
Gregor Mendel "Father of Genetics" |
Augustinian monk and botanist who formulated the laws of heredity based on his careful breeding experiments on garden pea plants. Later, he was recognized for his seminal works on genetics. |
