Presentation Transcript

  1. Genetics

  2. Genetics Key Terms • Genetics- is the study of heredity. • Heredity- is the passing of traits from parents to offspring. • Trait- a characteristic like hair color or eye color.

  3. Genetics Key Terms • Mendel- the father of genetics. • Mendel’s Law of Segregation- The two members of a gene pair (alleles) segregate (separate) from each other in the formation of gametes. 

  4. Genetics Key Terms • Mendel’s Law of Independent Assortment- When two or more characteristics are inherited individual hereditary factors assort independently during gamete production, giving different traits an equal opportunity of occurring together.

  5. Genetics Key Terms • Dominant Allele- the trait that is expressed or seen. Dominant alleles are represented by a capital letter.

  6. Genetics • Recessive Allele- the trait that is covered up or masked. • Recessive traits are represented by a lower case letter.

  7. Genetics Key Terms • Genotype- the organism’s genetic make up. • Phenotype- an organism’s physical appearance.

  8. Genetics Key Terms • Homozygous- when both alleles of a pair are alike. (Ex. TT or tt) • Heterozygous- when the two alleles in the pair are different. (Ex. Tt)

  9. Genetics Key Terms • Codominance- when two different alleles are fully expressed in a heterozygous individual. • Incomplete Dominance- when both alleles are partially expressed resulting in a new phenotype.

  10. Genetics • Offspring receive one allele for a trait from each parent. Complete Dragon Genetics.
