Inheritance

Trait- a characteristic; two genes control one trait (BB, Bb, bb) Hybrid- offspring of parents with contrasting trait Purebred- offspring of parents with similar traits that were bred true Homozygous- two similar genes (BB or bb) Heterozygous- two different genes (Bb) Dominant-gene is expressed even when it's with a contrasting gene (B) Recessive- hidden or masked gene(b) Gentoype-combination of genes (Bb or BB or bb) Phenotype- physical appearance of the genotype Allele- the different forms a gene can take, the possibilities 1 factor cross-one characteristic 2 factor cross- two characteristics P- parental F1- 1st filial (children) F2- 2nd filial (grandchildren) Law of Dominance- the dominant gene/trait is expressed even when it's with the contrasting gene Law of Segregation- genes separate during gamate separatory Law of Independent Assortment- different genes/traits are inherited separately Probability- # of times an event occurs/the possibility of the event occuring Test Cross- homozygous recessive Incomplete Dominance- Neither gene is completely dominant over the other one Codominance- contrasting alleles are both expressed
