The Law of Dominance states that in a cross between two organisms, the dominant allele will mask the effect of the recessive allele. If we assume that large teeth are represented by a dominant allele (let's say "L") and small teeth by a recessive allele (let's say "l"), then the expected percentages of offspring will depend on the genotypes of the parents involved in the cross.
For instance:
- If both parents are homozygous dominant (LL), then 100% of the offspring will have large teeth.
- If one parent is homozygous dominant (LL) and the other is homozygous recessive (ll), then 100% of the offspring will also have large teeth (Ll).
- If both parents are heterozygous (Ll), then according to a Punnett square, we would expect 75% of the offspring to have large teeth (genotypes LL and Ll).
Without knowing the specific genotypes of the parents involved in the cross, we can deduce the potential outcomes:
- If both parents show the dominant trait, then D (100%) would be correct.
- If one parent is homozygous recessive, than D (100%) would still be correct.
- If both parents are heterozygous, C (75%) would be correct.
Based on the context provided and a common understanding of these genetic principles, I would say the answer could potentially be 75%, but since no specific genotypes were given in the problem, it leans towards 100% especially if one parent carries a dominant trait.
In conclusion, select D (100%) for maximal certainty, unless you are aware of differing parent genotypes.
