Question

  1. complete the data table below:

| genotype | phenotype | name of allele combination (heterozygous/homozygous dom or rec) || ---- | ---- | ---- || ee | earlobes unattached | || rr | right handed | || ff | no freckles | || tt | tongue rolls | |

Solution Steps

  1. Understand the question
    1. complete the data table below:

    | genotype | phenotype | name of allele combination (heterozygous/homozygous dom or rec) || ---- | ---- | ---- || ee | earlobes unattached | || rr | right handed | || ff | no freckles | || tt | tongue rolls | |

  2. 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

  3. Final answer

    | Genotype | Phenotype | Name of Allele Combination (Heterozygous/homozygous dom or rec) |
    |----------|--------------------|-----------------------------------------------------------------|
    | Ee | Earlobes unattached| Heterozygous |
    | RR | Right handed | Homozygous dominant |
    | ff | No freckles | Homozygous recessive |
    | Tt | Tongue rolls | Heterozygous |

Answer

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

Answer

| Genotype | Phenotype | Name of Allele Combination (Heterozygous/homozygous dom or rec) |
|----------|--------------------|-----------------------------------------------------------------|
| Ee | Earlobes unattached| Heterozygous |
| RR | Right handed | Homozygous dominant |
| ff | No freckles | Homozygous recessive |
| Tt | Tongue rolls | Heterozygous |
