Pop & Eco 2

Front 1

Adaptation

Back 1

Any trait of an organism that increases its chances of surviving and reproducing

Front 2

Allele

Back 2

Variations of genes that determine traits in organisms; the twocorresponding alleles on two paired chromosomes constitute a gene

Front 3

Autotroph

Back 3

Organisms that make their own food

Front 4

Chromosome

Back 4

A structure that transfers hereditary information to the next generation

Front 5

Dominant allele

Back 5

A form of a gene that is expressed as the trait when a dominant allele is present

Front 6

Feature

Back 6

A structure, characteristic, or behavior of an organism, such as eye color, fur pattern, or timing of migration

Front 7

Gene

Back 7

The basic unit of heredity carried by the chromosomes; code for features of organisms

Front 8

Genotype

Back 8

An organism's particular combination of paired alleles

Front 9

Heterozygous gene

Back 9

A gene composed of two different alleles (a dominant and recessive allele)

Front 10

Homozygous gene

Back 10

A gene composed of two identical alleles. Either both alleles are dominant BB or both alleles are recessive bb

Front 11

Phenotype

Back 11

The traits produced by the genotype; the expression of the genes; the genes seen in photographs such as bb is seen as blue eyes in a photograph

Front 12

Recessive allele

Back 12

A form of a gene that is expressed as the trait only when a dominant allele is not present

Front 13

Trait

Back 13

The specific way a feature is expressed in an individual organism found in the phenotype

Front 14

Variation

Back 14

The range of expression of a trait within a population
