Question

Human blood types are determined by genes that follow the CODOMINANCE pattern of inheritance. There are two codominant alleles (A and B) and one recessive allele (o). Fill in the genotype for each person based on the description: Homozygous for the “B” allele Heterozygous for the “A” allele Type O Type AB Word Bank: AoBBBoooABAA Blank 1: Blank 2: Blank 3: Blank 4:

Answer 1

Based on the descriptions provided, we can fill in the genotypes for each person as follows:

1. **Homozygous for the “B” allele**: This person has two B alleles. The genotype is **BB**.

2. **Heterozygous for the “A” allele**: This person has one A allele and one O allele. The genotype is **Ao**.

3. **Type O**: Type O blood is represented by the genotype **oo** (homozygous recessive).

4. **Type AB**: Type AB blood is represented by the genotype **AB** (having one A and one B allele).

Now, filling in the blanks:

- **Blank 1**: BB
- **Blank 2**: Ao
- **Blank 3**: oo
- **Blank 4**: AB

So the complete response is:
- Blank 1: BB
- Blank 2: Ao
- Blank 3: oo
- Blank 4: AB
