An allele is...

• a variation of a gene

• the gene you get from your mom

• the gene you get from your dad

• the combination of traits that you have

A dominant allele is...

• the trait that will be hidden if there is only one copy

• the trait that will be visible if there is only one copy

• the trait that is always the most common in a population

• any version of a gene

A recessive allele is...

• the trait that will be hidden if there is only one copy

• the trait that will be visible if there is only one copy

• the trait that is always the most common in a population

• any version of a gene

A genotype is...

• the physical result of a phenotype (e.g. brown hair)

• how many genes you have

• the proportion of genes you have from you mom and from your dad

• the combination of alleles (e.g. TT)

A phenotype is...

• the combination of alleles (i.e. TT)

• the physical result of the genotype (e.g. brown hair)

• when the dominant trait is present

• the number of chromosomes you have
