TRAIT

A CHARACTERISTIC

THAT AN ORGANISM CAN PASS ON TO ITS OFFSPRING.

heredity

HEREDITY

A SET OF TRAITS AN ORGANISM

RECEIVES FROM

ITS PARENT.

genetics

GENETICS

THE STUDY OF HEREDITY

true breeding plant

TRUE-BREEDING PLANT

A PLANT THAT WILL ALWAYS PRODUCE OFFSPRING WITH THE SAME FORM OF TRAITS WHEN IT SELF-POLLINATES. Ex: TT or tt

cross pollination

CROSS- POLLINATION

WHEN THE POLLEN FROM ONE PLANT IS USED TO FERTILIZE ANOTHER PLANT.

slide6

GENE

A DNA UNIT THAT DETERMINES A TRAIT.

alleles

ALLELES

DIFFERENT FORMS OF A GENE.

dominant allele

DOMINANT ALLELE

THE FORM OF A GENE THAT, WHEN PRESENT,COVERS UP APPEARANCE OF THE RECESSIVE ALLELE.

recessive allele

RECESSIVE ALLELE

THE FORM OF A GENE THAT IS HIDDEN WHEN THE DOMINANT ALLELE IS PRESENT.

phenotype

PHENOTYPE

THE FORM OF A TRAIT THAT AN ORGANISM DISPLAYS.

genotype
GENOTYPE

THE ALLELES OF A GENE AN ORGANISM CONTAINS.

punnett square
PUNNETT SQUARE

SHOWS ALL OF THE POSSIBLE COMBINATIONS OF ALLELES FROM THE PARENTS.

probability
PROBABILITY

THE MATHEMATICAL CHANCE THAT AN EVENT WILL OCCUR.

incomplete dominance
INCOMPLETE DOMINANCE

WHEN THE PHENOTYPE OF THE TWO ALLELES BLEND.

codominance
CODOMINANCE

WHEN AN ORGANISM THAT HAS BOTH ALLELES OF A GENE DISPLAYS BOTH PHENOTYPES AT THE SAME TIME.

polygenic traits
POLYGENIC TRAITS

TRAITS THAT ARE DETERMINED BY MORE THAN ONE GENE.

heterozygous hybrid
HETEROZYGOUS/ Hybrid

HAVING DIFFERENT ALLELES FOR A TRAIT.

homozygous
HOMOZYGOUS

HAVING IDENTICAL ALLELES FOR A TRAIT.
