Definition
the different forms of a gene
ex:tall/short |
|
|
Term
|
Definition
| Passing on of physical characteristics form parent to offspring |

Term
|
Definition
| Characteristics of an organism that can have 2 or more different forms |
|
|
Term
|
Definition
segment of DNA that controls a genetic trait
(Actually controls the production of protein that controls the trait) |
|
|
Term
|
Definition
both copies of the gene for a trait are the same
ex: TT, tt, RR, rr
Homo. Dominant:both are for dominant trait(TT,RR)
Homo. Recessive:both are for recessive trait(tt,rr) |
|
|
Term
|
Definition
have 2 diff. copies of the gene for a particular trait.
(The dominant and recessive but only dominant shows)
ex:Tt. Rr |
|
|
Term
|
Definition
organism that has 2 diff alleles for a trait
ex: Tt, Rr |
|
|
Term
|
Definition
both alleles contribute to the phenotype of the organism
ex: AB blood-they have both |
|
|
Term
|
Definition
| one allele is not completely dominant over another. The heterozygous phenotype is between the other 2 phenotypes |
|
|
Term
|
Definition
a gene with more than 2 alleles possible in a population
ex: blood type(A,B,O) rabbit fur color(brown,black,white) |
|
|
Term
|
Definition
traits controlled by the interaction of several genes. These traits have a wide verity of phenotypes (multiple chromosomes)(Multiple genes working together to determine a trait)
ex:skin color(small changes/not distinct |
|
|
Term
|
Definition
occur when two traits are often expressed/inherited together. This is because they are located in close proximity on a chromosome, so they aren’t assorted during meiosis.
(close on 1 chromosome) (sex linked-occurs in males) |
