In co-dominance the genes of an allelomorphic pair express ............ and follow law of ..........

Options

A. Equally independent assortment
B. Unequally, dominance
C. Equally, segregation
D. Equally, dominance

Answer

To solve the question regarding co-dominance and the laws it follows, we can break it down into clear steps:

### Step-by-Step Solution:

1. **Understanding Co-dominance**:
- Co-dominance is a genetic phenomenon where both alleles in a heterozygote are fully expressed. This means that neither allele is dominant over the other, and both contribute to the phenotype.

2. **Example of Co-dominance**:
- A classic example of co-dominance is seen in blood groups. The A and B alleles are co-dominant, meaning that if an individual has one A allele and one B allele, they will express both A and B antigens on their red blood cells, resulting in the AB blood type.

3. **Expression of Genes**:
- In co-dominance, the genes of an allelomorphic pair express **equally**. This is a key characteristic that distinguishes co-dominance from complete dominance, where one allele completely masks the effect of another.

4. **Law of Segregation**:
- Co-dominance follows the **law of segregation**, which states that during the formation of gametes, the two alleles for a trait segregate from each other so that each gamete carries only one allele for each gene. This means that when gametes are formed, the alleles for A and B will separate, allowing for the possibility of both being expressed in the offspring.

5. **Final Answer**:
- Therefore, in co-dominance, the genes of an allelomorphic pair express **equally** and follow the law of **segregation**.
