GENOTYPE

A GENETIC TRAIT YOU CAN OBSERVE.

PHENOTYPE

THE TYPICAL APPEARANCE OF AN

INDIVIDUAL IN A NATURAL POPULATION.

WILD TYPE

An individual of a species that lacks pigment cells and

appears pinkish white.

ALBINO

(danio rerio) •Native to the Ganges River in India.•Tropical freshwater fish-needs warm water.•Easily and cheaply studied in the lab•Shares many characteristics with people

ZEBRAFISH

A trait that ONLY appears when NO

dominant genes are present (ex. blue eyes

and blonde hair in humans).

RECESSIVE TRAIT

A trait that appears MOST often in a

species (ex. brown eyes and brown hair in

humans).

DOMINANT TRAIT

A young organism before it emerges from

the egg.

EMBRYO

The part of the egg from which the

developing embryo gets nutrition.

YOLK

The entire genetic makeup of an

organism.

GENOME

A small dish that in which small organisms

can develop in a laboratory setting.

PETRI DISH

THE MATERIAL IN THE CELL NUCLEUS THAT

CONTAINS THE GENES (HUMANS HAVE 23

PAIRS).

CHROMOSOME

CELLS THAT CAN DEVELOP INTO MANY

OTHER TYPES OF CELLS AS THE EMBRYO
