  1. complete the data table below:
genotypephenotypename of allele combination (heterozygous/homozygous dom or rec)------------eeearlobes unattachedrrright handedffno frecklestttongue rolls

Explanation:

Step1: Define allele combination terms

Heterozygous = 1 dom +1 rec allele. Homozygous dom = 2 dom alleles. Homozygous rec = 2 rec alleles.

Step2: Analyze Ee genotype

E (dom) + e (rec) → heterozygous

Step3: Analyze RR genotype

2 dominant R alleles → homozygous dominant

Step4: Analyze ff genotype

2 recessive f alleles → homozygous recessive

Step5: Analyze Tt genotype

T (dom) + t (rec) → heterozygous
