|
How does a organism pass its characteristics onto its offspring? |
Meiosis |
|
|
Where does an organism get its unique characteristics? |
The transfer of genes from parents to offspring |
|
|
How are different forms of a gene distributed to offspring? |
When different combinations of traits are mixed from parents |
|
|
How can you predict the outcome of a genetic cross? |
Putting the traits in a Punnet Square |
|
|
How do alleles segregate when more than one gene is involved? |
Dominant and recessive traits |
|
|
What did Mendel contribute to our understanding of genetics? |
He figured out how dominant traits worked and how traits are passed down through generations |
|
|
Allele |
An allele is a variant form of a gene |
|
|
Gene |
act as instructions to make molecules called proteins |
|
|
trait |
a distinguishing quality or characteristic, typically one belonging to a person. |
|
|
Genetics |
Genetics is the study of genes |
|
|
Heterozygous |
A diploid organism is heterozygous at a gene locus when its cells contain two different alleles of a gene. |
|
|
Homozygous |
When an individual has two of the same allele, whether dominant or recessive |
|
|
Hybrid |
the offspring of two plants or animals of different species or varieties |
|
|
Independent Assortment |
describes how different genes independently separate from one another when reproductive cells develop |
|
|
Principle of Dominance |
hybridized two parents with different versions of a particular trait, one of those versions apparently disappeared in the hybrid (heterozygous) offspring. |
|
|
Segregation |
the action or state of setting someone or something apart from other people or things or being set apart. |
|
|
Phenotype |
individual's observable traits, such as height, eye color |
|
|
Genotype |
individual's collection of genes |
|
|
probability |
measure of the likelihood that an event will occur. |
|
|
Punnett Square |
diagram that is used to predict an outcome of a particular cross or breeding experiment |
