Question

determine the genotypes for each using the information in the chart.
trait | dominant allele | recessive allele
eye color | brown (b) | blue (b)
hair color | brown (h) | blonde (h)
mouth shape | thick (m) | thin (m)
eye shape | round (r) | oval (r)
drag & drop the answer
heterozygous thick mouth
homozygous brown eyes
homozygous blonde hair
heterozygous round eyes
genotype options: bb, ee, mm, ee, hh, hh, bb, mm, hh, mm (approximate text from the image)

Explanation:

Step1: Heterozygous thick mouth

Heterozygous means two different alleles. Thick (M) is dominant, thin (m) is recessive. So genotype is $Mm$.

Step2: Homozygous brown eyes

Homozygous means two same dominant alleles. Brown (B) is dominant. So genotype is $BB$.

Step3: Homozygous blonde hair

Homozygous means two same recessive alleles. Blonde (h) is recessive. So genotype is $hh$.

Step4: Heterozygous round eyes

Heterozygous means two different alleles. Round (R) is dominant, oval (r) is recessive. Wait, correction: Eye shape - round (R) dominant, oval (r) recessive? Wait, no, the table: Eye shape dominant is Round (R)? Wait, the trait: Eye shape, dominant Round (R), recessive Oval (e)? Wait, maybe typo, but for round eyes heterozygous: dominant allele (R) and recessive (r or e). Wait, the drag options: for eye shape, the alleles are E, e? Wait, the left drag options: EE, Ee, ee for eye shape? Wait, re - examining:

Wait, the problem is about matching phenotypes to genotypes. Let's re - do:

1. Heterozygous thick mouth: Thick is M (dominant), thin is m (recessive). Heterozygous: $Mm$.
2. Homozygous brown eyes: Brown is B (dominant), so homozygous dominant: $BB$.
3. Homozygous blonde hair: Blonde is h (recessive), so homozygous recessive: $hh$.
4. Heterozygous round eyes: Round is E (dominant), oval is e (recessive). Heterozygous: $Ee$.

Answer:

• Heterozygous thick mouth: $Mm$
• Homozygous brown eyes: $BB$
• Homozygous blonde hair: $hh$
• Heterozygous round eyes: $Ee$
