Heredity#1
An organism that has two identical alleles for a trait.
Homozygous
Is one whose trait always show up in the organism when the allele is present
Dominant Allele
Occurs when one allele is only partially dominant
Incomplete Dominance
Is a number that describes how likely it is that an event will occur
Probability
Three or more possible alleles determine the trait.
Multiple Alleles
The organism is the offspring of many generations that have the same forms of a trait.
Purebred
Occurs when both alleles for a gene are expressed equally
Co-Dominance
To describe the factors that control a trait.
Gene
A new organism begins to form when egg and sperm cells join in the process.
Fertilization
Is hidden whenever the dominant allele is present.
Recessive Allele
Occurs when more than one gene affects a trait
Polygenic Inheritance
The passing of physical characteristics from parent to offspring
Heredity
Phenotype
An organism that has two different alleles for a trait
Ex. Bb
Heterozygous
Genetics
Each specific characteristics as stem, height, or seed color is called....
Trait
An organisms genetic make up
Genotype
Is a chart that shows all true possible ways alleles can combine in a genetic cross
An organism that has two different alleles for a trait
Hybrid
