Definition
| different versions of genes |
|
|
Term
|
Definition
| where alleles for a particular gene can be found on a chromosome |
|
|
Term
|
Definition
| a set of alleles that and individual organism possess |
|
|
Term
| homozygous vs. heterozygous |
|
Definition
Homo - two identical alleles
Heter - two different alleles |
|
|
Term
|
Definition
| manifestation or apperance of a characteristic |
|
|
Term
|
Definition
| a cross between parents that differ in a single characteristic |
|
|
Term
P generation vs. F1 generation
|
|
Definition
P - the parental generation
F1 - the P generations offspring |
|
|
Term
|
Definition
Crosses in which the phenotypes of the male and female parents are reversed.
Ex: A tall male is crossed with a short female, in the other cross, a tall female is crossed with a short male |
|
|
Term
|
Definition
| The offspring of a self-fertilizing F1 generation |
|
|
Term
|
Definition
Individual diploid organisms possess 2 alleles for any particular characteristic
The 2 alleles segragate when gametes a formed
1 allele goes to into each gamete |
|
|
Term
|
Definition
| when 2 different alleles are present in a genotype, only the trait encoded by one of then, the "dominent" allele, is observed in the phenotype |
|
|
Term
| chromosome heredity theory |
|
Definition
| genes are located on chromosomes |
|
|
Term
|
Definition
| A cross between an F1 genotype and either of the parental genotypes |
|
|
Term
|
Definition
The likelihood of the occurance of a particular event.
The number of times an event will occur. |
|
|
Term
|
Definition
The probability of of 2 or more independent events occuring together is calculated by multiplying their individual probabilities.

|
Term
|
Definition
The probability of any one of two or mutually exclusive events is calculated by addin the probability of these events.
Keywords = either, or |

Term
|
Definition
One individual of an unknown genotype is crossed with a homozygous recessive genotype with the trait in question.
It reveals the genotype of the first individual. |
|
|
Term
|
Definition
When the heterozygote has a phenotyoe intermediate, betweent the 2 homozygotes
Genotype and Phenotype ratios are the same |
|
|
Term
|
Definition
| A trait or allele that is commonly found in natural (wild) populations |
|
|
Term
| Principle of Independent Assortment |
|
Definition
| Alleles at different loci separate independently of one another. |
|
|
Term
| goodness-of-fit chi-square test |
|
Definition
- evaluates the role of chance in producing deviations between observed and expected values
- provides info. about how well observed values fit expected values
