  1. Genetics Short Review

  2. PRACTICE Review The principle of dominance state that • all alleles are dominant. • all alleles are recessive. • some alleles are dominant and others are recessive. • alleles are neither dominant or recessive.

  3. PRACTICE Review The principle of dominance state that • all alleles are dominant. • all alleles are recessive. • some alleles are dominant and others are recessive. • alleles are neither dominant or recessive.

  4. PRACTICE Review Organisms that have two different alleles for a particular trait are said to be • Hybrid • Dominant • Homozygous • Heterozygous

  5. PRACTICE Review Organisms that have two different alleles for a particular trait are said to be • Hybrid • Dominant • Homozygous • Heterozygous

  6. PRACTICE Review The ____________________ is the set of alleles an organism has for a particular trait. Usually written, for example: RR, Rr, bb

  7. PRACTICE Review GENOTYPE

  8. PRACTICE Review What the resulting trait actually looks like is called the ________________ or physical trait. Usually written, for example: Red, Round, Tall

  9. PRACTICE Review PHENOTYPE

  10. PRACTICE Review When Gregor Mendel crossed a true-breeding tall plant with a true-breeding short plant in the P generation, the F1 plants inherited a. An allele for shortness from each parent. b. An allele for tallness from each parent. c. An allele from only the tall parent. d. An allele for tallness from the tall parent and an allele for shortness from the short parent.

  11. PRACTICE Review When Gregor Mendel crossed a true-breeding tall plant with a true-breeding short plant in the P generation, the F1 plants inherited a. An allele for shortness from each parent. b. An allele for tallness from each parent. c. An allele from only the tall parent. d. An allele for tallness from the tall parent and an allele for shortness from the short parent.

  12. Method!! After studying specific traits (characteristics that vary by plant) True-Breeding: If self-pollinated, then only produce offspring identical to self. Hybrids: The offspring crosses between parents with different traits.
