Which of the following genotypes is homozygous recessive?

• RR
• Rr

when one allele is not completely dominant over the other - blending of two traits

• Codominance
• Complete dominance
• incomplete dominance
• none of these

condition in which both alleles for a gene are expressed when present - both traits are visible

• Codominance
• Dominance
• Complete dominance
• Incomplete dominance
