Patterns of Inheritance

Patterns of Inheritance. Chapter 12. Early Ideas of Heredity. Before the 20 th century, 2 concepts were the basis for ideas about heredity: -heredity occurs within species -traits are transmitted directly from parent to offspring

Basics of DNA

Basics of DNA. Todd Rightmire Mt. Baker High School. Cellular composition. DNA is contained in nucleus of cell Phospho-lipids and proteins combined to form cell membrane Lipids are fats. DNA (DeoxyriboNucleic Acid) is a double helix. Backbone is made of sugar-phosphate

Dominance and Dihybrid Cross

Dominance and Dihybrid Cross. Incomplete Dominance. Heterozygous phenotype (trait expressed) is somewhere in between the two homozygous phenotypes. Genes mix EX: Red rose x White rose = Pink rose. Codominance. Both alleles contribute to the phenotype (traits expressed) You see both traits

10.3 Polygenic Inheritance

10.3 Polygenic Inheritance. HL Material. Polygenic Inheritance. Concerns a single characteristic that is controlled by more than one gene Each allele only contributes a small amount to the overall phenotype of the individual The more genes involved, the more variation

Predicting Results of Dihybrid Crosses

Predicting Results of Dihybrid Crosses. A cross in which two characteristics are tracked is a dihybrid cross. The two characteristics are assumed to have genes located on different chromosomes. Alleles for each characteristic will independently assort when forming gametes.
