Asked by john

A student recorded the height of each student in the school. She then made a bar graph of her results. She observed that the results form a bell-shaped curve. The student could use her graph as evidence to support which argument?
Height is affected by multiple pairs of genes on different chromosomes.
The alleles for tall height and short height are codominant.
The allele for being tall is dominant to the allele for shorter heights.
There are three alleles for height that demonstrate incomplete dominance

"Height is affected by multiple pairs of genes on different chromosomes."

Reason: A bell-shaped (continuous) distribution indicates many genes each contributing small effects (polygenic inheritance), often plus environmental influence, producing a normal curve. The other choices describe single-gene or discrete patterns (codominance, simple dominance, or a few alleles with incomplete dominance) that give distinct phenotype classes, not a smooth bell-shaped distribution.
