Capital letters are used to show that an allele is -

• dominant

• recessive

• neither

Lower case letters are used to show that an allele is -

• dominant

• recessive

• neither

Kevin has dimples, but his gene combination shows up as Dd. This letter combination is called-

• genotype

• phenotype

• allele

Kevin has dimples which is a stronger allele. His physical trait of dimples is called-

• genotype

• phenotype

• allele

Kevin has dimples which is a stronger allele that takes over when it is present. This allele is-

• dominant

• recessive

• neither dominant or recessive

If having dimples is the stronger allele, then not having dimples is the weaker allele. What type of alleles are weaker?

• dominant

• recessive

• neither dominant or recessive
