A version of a gene
Genotype
Is the genetic makeup of an organism
Phenotype
Is a persons appearance due to the environment and genotype
Homozygous
When the alleles of a particular gene are identical
Heterozygous
When the alleles of a particular gene are different
Dominant alleles
Are always shown in the phenotype
Recessive alleles
Are only showed in the phenotype if there are no dominant alleles
Haploid
Cells have one copy of each chromosome
Diploid
Have two copies of each chromosome
Co-dominance
When both alleles are expressed in the phenotype
Use different us scripted letters to show this in monohybrid crosses
Multiple alleles
