Based on Mendel’s laws and the information provided, select which statement(s) are accurate.
100% of offspring will have 2 arms.
50% of offspring will have 4 arms.
2:4 of the offspring will have 2 arms.
4 arms is the dominant trait.
The dominant trait is 2 arms.
Based on Mendel’s laws, let’s analyze the statements:
1. 100% of offspring will have 2 arms: This depends on the dominant and recessive traits. If 2 arms are dominant, and both parents contribute 2 arms, this could be true.
2. 50% of offspring will have 4 arms: This could only be true if one parent has 4 arms (recessive trait) and the other has 2 arms (dominant trait), and they are heterozygous.
3. 2:4 of the offspring will have 2 arms: This suggests a ratio that is inconsistent with Mendelian genetics, as we typically discuss 1:2:1 or 3:1 ratios.
4. 4 arms is the dominant trait: This contradicts the common understanding; typically, the trait that appears more frequently in the offspring is dominant.
5. The dominant trait is 2 arms: This could be true if 2 arms are the more prevalent trait in the observed offspring.
In summary, statements about the exact ratios depend on the parental genotypes, but without additional context, the most reasonable inference is that if 2 arms are generally the trait observed, then the dominant trait is likely 2 arms.
