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

Genotypes- describe on the handout Female’s Genotype Male’s Genotype

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

Female Phenotype • Wings: • Forelimbs • Hindlimbs • Tail

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

Male Genotype • Wings: • Forelimbs • Hindlimbs • Tail

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

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

Guess the Father’s Genes • Wings • Forelimbs • Hindlimbs • Tail:

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 Dominant / Recessive • Wings • Forelimbs • Example – for tall or short we might use T for Tall • Hindlimbs and t for short • How would you indicate • Tail each of the 4 traits we’ve looked at:

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?

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?

• 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?
