Heredity,Punnett Squares, & Probability Power Point Presentation
- 1. Heredity, Genetics Punnett Squares & Probability Mr. Miller
- 2. Lets find out if the two pigeons on the left produce offspring that have the traits of the pigeon on the right
- 5. Now lets set up the Punnet Square T t t t T T t t t t t t
- 11. Now lets look at the possible genotypes and the phenotypes that will be expressed Z Z z z z z z Z Z Z z Z There is a single possibility of inheriting a homozygous (pure) dominant genotype which will produce a phenotype with grey feathers There are two possibilities of inheriting heterozygous (hybrid) genotypes which will produce a phenotype with grey feathers
- 12. Now lets look at the possible genotypes and the phenotypes that will be expressed Z Z z z z z z Z Z Z z Z There is a single possibility of inheriting a homozygous (pure) recessive genotype which will produce a phenotype with white feathers So two grey birds can produce a pigeon with white feathers!
