Genetics
Inheritance Patterns
Complete Dominance
Heterozygous phenotypic expression is just the dominant trait
Incomplete Dominance
heterozygous expression is a mixture of both the dominant and recessive phenotype
ex: a red and white flower create a pink flower
Co-Dominance
Heterozygous phenotypic expression is a seperate but simultaneous expression of both traits
Ex: Blood Types
AB blood type leads to the expression of blood with both a and b antigens
Laws that govern genetic expression
Law of Dominance
ability of the dominant allele to mask the expression of the recessive allele
meiosis
dihybrid and monohybrid crosses
complete dominant inheritance pattern
Law of Segregation
homologous chromosomes separate in a way so each gamete only receives one set of genetic information
meiosis I
dihybrid and monohybrid crosses
all inheritance patterns
Law of Independent Assortment
chromosomes separate in a way that does not influence other pairs of chromosomes
dihybrid crosses
meiosis I
all inheritance patterns
