Question

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.

Explanation:

A bell - shaped curve in the distribution of student heights suggests polygenic inheritance. Polygenic traits are influenced by multiple pairs of genes on different chromosomes. Codominance, simple dominance, and incomplete dominance of a small number of alleles do not typically produce a bell - shaped distribution for a trait like height.

Answer:

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