Presentation Transcript

  1. TRAIT A CHARACTERISTIC THAT AN ORGANISM CAN PASS ON TO ITS OFFSPRING.

  2. HEREDITY A SET OF TRAITS AN ORGANISM RECEIVES FROM ITS PARENT.

  3. GENETICS THE STUDY OF HEREDITY

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

  5. CROSS- POLLINATION WHEN THE POLLEN FROM ONE PLANT IS USED TO FERTILIZE ANOTHER PLANT.

  6. GENE A DNA UNIT THAT DETERMINES A TRAIT.

  7. ALLELES DIFFERENT FORMS OF A GENE.

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

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

  10. PHENOTYPE THE FORM OF A TRAIT THAT AN ORGANISM DISPLAYS.

  11. GENOTYPE THE ALLELES OF A GENE AN ORGANISM CONTAINS.

  12. PUNNETT SQUARE SHOWS ALL OF THE POSSIBLE COMBINATIONS OF ALLELES FROM THE PARENTS.

  13. PROBABILITY THE MATHEMATICAL CHANCE THAT AN EVENT WILL OCCUR.

  14. INCOMPLETE DOMINANCE WHEN THE PHENOTYPE OF THE TWO ALLELES BLEND.

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

  16. POLYGENIC TRAITS TRAITS THAT ARE DETERMINED BY MORE THAN ONE GENE.

  17. HETEROZYGOUS/ Hybrid HAVING DIFFERENT ALLELES FOR A TRAIT.

  18. HOMOZYGOUS HAVING IDENTICAL ALLELES FOR A TRAIT.
