|
asexual reproduction |
Reproduction that involves one parent. Offspring is identical to parent.For example, when a pea plant pollinates itself |
|
|
Sexual reproduction |
Reproduction that involves two parents and combines their genetic material. Offspring will have traits of both parents. For example, cross pollinating pea plants. |
|
|
Genes |
Controls the traits of an organism. |
|
|
Alleles |
Different forms of the same gene. Each organism has 2 alleles for each trait. |
|
|
Dominant trait |
Dominant Trait- The trait that is observed (Represented by an uppercase letter) |
|
|
Recessive trait |
The trait that is hidden (Represented by a lowercase letter) |
|
|
Phenotype |
They way an organism looks (Red hair or Brown hair) |
|
|
Genotype |
The gene combination ( TT, Tt, tt) |
|
|
Homozygous |
When the gene combination is the same (TT or tt) |
|
|
Heterozygous |
When the gene combination is different (Tt) |
|
|
Trait |
A specific characteristic that an organism can pass to its offspring through its genes. |
|
|
Probability |
A number that describes how likely it is that a particular event will occur |
|
|
Hybrid |
An offspring of crosses that has 2 different alleles for a trait. |
|
|
