  1. Genetics Vocabulary Review Quiz #1

  2. Genetics The study of genes and how they are inherited Genome The complete copy of the genetic code for an organism Allele Alternate form of a gene, example: tongue roller or non- tongue roller, type B or type A or type O blood Gene The code for making a protein, that will be expressed

  3. HeterozygousWhen the genotype has two different alleles, Tt or YyHomozygousWhen the genotype has two of the same letters, HH or hh Genotype The 2 alleles an individual inherits for a trait, TT or Ww or yy Phenotype The physical expression of the alleles, example a pea plant is either Tall or Short

  4. Multiple AllelesWhen there is more than two alternate forms of a gene, example blood type A, B, or O there are three different alleles for blood proteinTest CrossCrossing an unknown individual with a known individual to determine the genetic makeup of the unknown Incomplete dominance When two alleles are both dominant, but the phenotype is expressed as an intermediate or blend of the two, example when a allele B- black and allele W- white in the heterozygous BW – make gray, or R-red and W-white make RW- pink Codominance When two alleles are both dominant but the phenotype is expressed equally between the two, example is when B- black feathers, and W- white feathers and BW- black and white feathered bird

  5. The complete copy of the genetic code for an organism Genome

  6. When there is more than two alternate forms of a gene, example blood type A, B, or O there are three different alleles for blood protein Multiple Alleles

  7. Alternate form of a gene, example: tongue roller or non- tongue roller, type B or type A or type O blood Allele

  8. When the genotype has two different alleles, Tt or Yy Heterozygous

  9. The physical expression of the alleles, example a pea plant is either Tall or Short Phenotype

  10. Crossing an unknown individual with a known individual to determine the genetic makeup of the unknown Test cross

  11. The 2 alleles an individual inherits for a trait, what the gene says, TT or Ww or yy Genotype

  12. When two alleles are both dominant but the phenotype is expressed equally between the two, example is when B- black feathers, and W- white feathers and BW- black and white feathered bird Codominance

  13. When the genotype has two of the same letters, HH or hh Homozygous

  14. When two alleles are both dominant, but the phenotype is expressed as an intermediate or blend of the two, example when a allele B- black and allele W- white in the heterozygous BW – make gray, or R-red and W-white make RW- pink Incomplete dominance

  15. The study of genes and how they are inherited Genetics

  16. The code for making a protein that will be expressed, hundreds can be found on a single chromosome Gene
