A scientist crossed two plants with heterozygous maize genes - GED Prep

Question

A scientist crossed two plants with heterozygous maize genes and found out that its young plants had traits in the ratio of 9:3:3:1. The highest percentage of the offspring had a dominant gene while very few had recessive genes, implying that the traits have been inherited differently from each plant.

Another similar experiment was conducted using heterozygous beans seed for flower color and pollen shape. The results did not match the results 9:3:3;1 above. This means that some traits were never inherited independently. The results are as shown

How does the second result affect the interpretation of the first scientist

Answers

correct

The second experimental results show that the first experiment's conclusions were incomplete.
The second experiment's resulted in different ratios of traits in the offspring, confirming the first experiment' s conclusion.
The second experiment studied different traits than the first experiment so the second experiment's results could not challenge or support the first experiment's conclusions.
The second experiment's results show that the first experiment's conclusions were incorrect.

Explanation

The first experiment found out that the plant’s trait are inherited by the new offspring independently. The second investigation challenges the first one since the offspring ration did not match what had been observed in the first investigation. This implies that a few traits may be linked or inherited together rather than independently. Therefore, the findings of the first experiment were incomplete.
