The observable traits dictated by the genotype
Phenotype
Genotype
Homozygous Recessive
Homozygous Dominant
During meiosis and gamete formation, homologous (paired up) alleles split up
Phenotype
Law of Segregation
Genotype
Dihybrid Cross
During meiosis, the homologous pairs of chromosomes and the matching alleles are lined up independently.
Offspring are a mix of maternal genes and paternal genes.
This increases genetic variation.
Homozygous Dominant
Law of Segregation
Crossing Over
Independent Assortment
The genetic cross between two parents for one trait:
Example BB x bb
B = dominant for brown
b = recessive for blue
Incomplete Dominance
Dihybrid Cross
Monohybrid Cross
Iron Cross
The ratio of homozygous dominant to heterozygous
to homozygous recessive offspring
Genotypic Ratio
Phenotypic Ratio
Monohybrid Cross
Homologous Pair
