  1. Genetics Review

  2. Ready???? • Yes • No 10

  3. Who became known as the father of genetics? • Watson • Einstein • Mendel • Bohr 10

  4. What two terms for traits did Mendel develop? • Dominant and recessive • Big and little • Hidden and unhidden • First and second 10

  5. What generation does the F1 generation come from? • P • F1 • F2 • F3 10

  6. Genetic make-up of an organism • Phenotype • Genotype • Allele • Hybrid 10

  7. Different forms of a gene • Allele • Punnett square • Traits • DNA 10

  8. An organism with different alleles for one trait • Homozygous • Heterozygous • Pure • Dominant 10

  9. Is covered up when the dominant form is present • Dominant trait • Recessive trait • Gene • phenotype 10

  10. Two alleles which are the same for a trait • Homozygous • Heterozygous • Hybrid • Phenotype 10

  11. An offspring which receives no dominant alleles will have this phenotype • Hybrid • Dominant • Recessive • rr 10

  12. All possible combinations of offspring Can be calculated by using a ________. • Pedigree • Genotype • Graph • Punnett Square 10

  13. If both parents of an offspring are hybrid, what is the probability that the offspring will have the dominant trait? • 0% • 25% • 50% • 75% 10

  14. The idea that each gene is inherited separately from any other gene is called the ______________. • Law of Independent Assortment • Law of Segregation • Law of Alleles • Law of Dominance 10

  15. Hair color, skin color and height are all examples of _________ traits. • Dominant • Heterozygous • Polygenic • Recessive 10

  16. What type of inheritance produces an intermediate phenotype for the heterozygous genotype? • Complete • Incomplete • Polygenic • Dihybrid 10

  17. A ___________ is used to find the genotype of an unknown organism which has the dominant phenotype. • Test Cross • Hybrid Cross • Pure Cross • All of the above 10

  18. In a test cross the unknown organism is always crossed with a organism with a ________ phenotype. • Dominant • Recessive • Hybrid • Heterozygous 10

  19. What is the genotype for a monster that is heterozygous for purple fur color and has long hair. P= Purple Hair p= Black hair S = Short hair s = long hair • PPss • PpSS • PpSs • Ppss 10

  20. Heterozygous genotypes are also said to be called _________ because they carry both alleles for a specific trait. • Pure • Homozygous • Hybrids • Alleles 10

  21. What is the probability that an offspring will have green eyes? • 0% • 50% • 75% • 100% R = red eyes r = green eyes 10

  34. What is the genotype for individual 10? • AA • A_ • Aa • aa 10

  35. In some cows the gene for fur color is controlled by codominance. The allele for red is equally dominant with the allele for white. The heterozygous phenotype is known as roan. What is the genotype for roan? • Rr • RR • RW • rr 10

  36. The cross of a red flower and a yellow flowers creates orange flowers. What type of inheritance is this? • Complete Dominance • Codominance • Incomplete Dominance • Sex Linked 10

  37. In which type of inheritance are two phenotypes expressed at the same time? • Complete Dominance • Codominance • Incomplete Dominance • Sex Linked 10

  38. Eye color in fruit flies is a sex linked trait. Red is dominant to white. When a white eyed female and a red eyed male are crossed, what percent of the male offspring will have red eyes? • 0 • 25 • 50 • 100 10
