Genetics College Biology
Gregor Mendel Mid 1800’s, Austrian monk. Introduced probability to genetics Mated pea plants
Cross-pollination Produce seeds that have two different plants as parents
Traits Specific characteristic
Genes Chemical factors that determine traits
Alleles Different forms of the gene
The Principle of Dominance States that some alleles are dominant and others are recessive.
Law of Segregation Alleles for each trait are segregated from each other during the formation of sex cells, gametes.
Probability Likelihood that a particular event will occur.
Punnett Squares Used to predict and compare the genetic variations that will result from a cross
Homozygous Two identical alleles - Dominant: TT - Recessive: tt
Heterozygous Two different alleles
Phenotype Physical characteristics
Genotype Genetic makeup
Law of Independent Assortment Genes of different traits can segregate independently of each other Dihybrid cross
Incomplete Dominance Heterozygous phenotypes are a mix of the two homozygous parents
Codominance Both alleles contribute to the phenotype
Multiple Alleles: more than two alleles
Polygenic Traits Having many genes that determine a trait Skin color, eye color
