Character |
An organisms particular attribute |
|
|
|
Trait |
State of the character |
|
|
|
True Breeding |
Plants that produce offspring of the same variety when self fertilized |
|
|
|
Hybridization |
Crossing two contrasting, true-breeding varieties |
|
|
|
P Generation |
True breeding cross (parental) |
|
|

|
|
|
Homozygous |
An organism with two identical alleles for a character (gene) |
|
|
|
Heterozygous |
An organism with two different alleles for a gene |
|
|
|
Phenotype |
An organisms physical appearance |
|
|
|
Genotype |
An organisms genetic make up |
|
|
|
Mendel's Law of Segregation |
In a monohybrid veils the two alleles for a heritable character separate during gamete formation and end up in different gametes. |
|
|
|
Mendel's Law of Independent Assortment |
In a dihybrid cross, each pair of alleles segregates independently of each other pair of alleles during gamete formation. |
|
|
|
When one characteristic is controlled by two or more genes. |
Polygenic inheritance |
|
|
|
A variation that has no limit on the value that can occur within a population (e.g height, weight) |
Continuous Variation |
|
|
|
A measurable phenotype that depends on the actions of many genes and the environment |
Quantitative Traits |
|
|
|
Pleiotropic |
An allele that has more than one effect the phenotype |
|
|
|
Incomplete Dominance |
The heterozygote is is intermediate in appearance between the two homozygotes |
Red flower + white flower = pink |
|
|
Codominance |
No single gene is dominant, each had its own effect on the phenotype and the heterozygote shows some aspect of both homozygotes |
Ex. ABO blood type |
|
|
The four different cell surface types |
ABO blood types |
|
|
|
Somatic cell |
Any diploid cell that is not a sperm or egg |
|
|
|
Barr Body |
The inactive x chromosome in the female somatic cell |
