Adding purple flowers and white flowers together will make somepurple flowers and maybe some white flowers
If you repeat the process of adding purple and white flowers, taking away white flowers every time, you will get a true breeding line
Combining true-breededpurple flowers to white flowers will make all purple hybrids. If you combine purple hybrids with more purple hybrids, white flowers will slowly start to show up more.
A recessive trait is a trait that is hidden in any given generation.
Flowers being mixed first are the Parent Generation.
Flowers produced from the parent generation are called the first filial Generation (or F1)
Phenotype: observable characteristics, or traits
Alleles: An alternative form of a gene (i.e. R=rigid r=smooth)
Dominant alleles: mask recessive alleles
Recessive alleles: get masked by Dominant alleles
Genotype: The combination of alleles an organism has for a gene
(i.e. HzD, Htrz, HzR)
Homozygous Dominant (HzD): Two dominant traits (PP)
Heterozygous (HtrZ): One dominant trait and one recessive trait (Pp)
Homozygous Recessive (HzR): two recessive traits (pp)
Dihybrid Cross: Tracking inheritance of two traits (i.e. YyRr x yyRR)
