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
