Answer 1

Gene A was observed to inhibit the expression of gene C, as identified through experiments where gene A's activity corresponded with a reduction or absence of gene C's expression, a concept known as epistasis.

Step-by-step explanation:

When Elliott Meyerowitz and his colleagues were studying flower development, they observed that certain gene interactions play a crucial role in this process.

One such interaction is between gene A and gene C. The conclusion that gene A inhibits the expression of gene C was likely reached through experiments that showed when gene A is active, gene C's expression is reduced or absent.

This phenomenon is known as epistasis, where the expression of one gene masks or modifies the expression of another gene. Epistasis can often be identified through genetic crosses and examination of phenotypes that do not follow expected Mendelian ratios, indicating interaction between genes.
