When dominant and recessive alleles express itself together it is called [2001]a)codominanceb)dominancec)amphidominaced)pseudodominanceCorrect answer is option 'A'. Can you explain this answer?

Question

Answer

The crt answer for this question is pseudo dominance. In the question they have said that both the dominant and recessive alleles express. But in case of codominance both the dominant alleles  expresses. Not the dominant and recessive. In case of blood groups in humans both the alleles A and B are equally dominant and not differentiated as dominant or recessive. So the crt answer is pseudo dominance

Answer

Yeah , it is known as codominance becoz both alleles will show their character in next generation...

Answer

Answer:
When dominant and recessive alleles express themselves together, it is called codominance. In this scenario, both alleles are expressed and contribute to the phenotype of the individual. This is in contrast to dominance, where the dominant allele masks the expression of the recessive allele.

Explanation:
When an organism inherits two different alleles for a particular trait, one dominant and one recessive, the dominant allele usually masks or suppresses the expression of the recessive allele. This is called dominance. However, in some cases, both alleles are expressed simultaneously, leading to codominance.

Examples of Codominance:
1. Blood Type: The ABO blood group system is an example of codominance. There are three alleles involved: A, B, and O. The A and B alleles are codominant, while the O allele is recessive. If an individual inherits the A allele from one parent and the B allele from the other, both alleles are expressed, resulting in the AB blood type.

2. Coat Color in Cattle: Another example of codominance can be observed in cattle coat color. The alleles for coat color in cattle are represented by the letters R, Roan, and W, White. The Roan allele (R) produces a coat with a mixture of red and white hairs, while the White allele (W) produces a completely white coat. When a cow inherits one R allele and one W allele, both alleles are expressed, resulting in a coat with both red and white hairs.

Key Points:
- Codominance occurs when both dominant and recessive alleles are expressed together.
- Both alleles contribute to the phenotype of the individual.
- Codominance can be observed in traits such as blood type and coat color in animals.
- In the case of codominance, there is no dominance or suppression of one allele over the other.
- The result is a phenotype that shows a combination of both traits or characteristics associated with the alleles involved.
