3. Do the dragons have to have identical genes to look the same? Answer on the handout

4. Genotypes- describe on the handout Female’s GenotypeMale’s Genotype

5. What do you think this dragon looks like? Wings: Forelimbs: Hindlimbs: Tail:

6. Female Phenotype Wings: Forelimbs Hindlimbs Tail

7. What does this dragon look like? Wings: Forelimbs: Hindlimbs: Tail:

8. Male Genotype Wings: Forelimbs Hindlimbs Tail

9. Vocabulary The gene for wings is dominant and the gene for no wings is recessive. What does dominant mean? What does recessive mean?

10. Genotype and phenotype Look back at the slides – What does genotype refer to? What does phenotype refer to?

11. Guess the Father’s Genes Wings Forelimbs Hindlimbs Tail:

12. Indicating Dominant and Recessive We usually use a single letter to indicate any trait: – Capital letter for the dominant trait – Lower case for the recessive trait Example – for tall or short we might use T for Tall and t for short How would you indicate each of the 4 traits we’ve looked at: Dominant / Recessive Wings Forelimbs Hindlimbs Tail

13. Hetero and Homozygous Having the same gene for a trait on both parental chromosomes is homozygous Having a different gene for a trait on each parental chromosome is heterozygous This dragon is heterozygous for which trait? Homozygous for which trait?

14. What genotype and phenotype? What is the genotype for a dragon that is heterozygous for wings? What is the phenotype for a dragon that is heterozygous for wings?

15. What is the genotype for a dragon that is homozygous for no hindlimbs? What is the phenotype for a dragon that is homozygous for no hindlimbs?
