Which mendelian idea is depicted by a cross in which the F1 generation resembles both the parents ?a)incomplete dominanceb)law of dominancec)inheritance of one gened)co-dominanceCorrect answer is option 'B'. Can you explain this answer?

Question

Answer

In Codominance, both alleles of a pair express themselves fully in F1 hybrid, so, it resembles both the parents. In incomplete dominance, the two genes of an allelomorphic pair are not related as dominant or recessive but each of them expresses itself partially.

Answer

Answer

Law of Dominance
The Law of Dominance states that in a cross between two parents that are homozygous for different alleles of a gene, the dominant allele will be expressed in the offspring while the recessive allele will be masked. However, in some cases, the F1 generation may resemble both parents, indicating that the Law of Dominance is not being followed.

Explanation
When the F1 generation resembles both parents in a cross, it suggests that neither allele is completely dominant over the other. This can occur in cases of incomplete dominance or co-dominance. However, in this scenario, the question specifically mentions that the mendelian idea being depicted is when the F1 generation resembles both parents. This is a clear indication of the Law of Dominance being violated.
In the Law of Dominance, one allele is dominant over the other, leading to a clear dominant phenotype in the offspring. When both parents are expressed in the F1 generation, it indicates that neither allele is fully dominant, and both alleles are being expressed equally.
Therefore, the correct mendelian idea depicted by a cross in which the F1 generation resembles both parents is the Law of Dominance.
