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.
tre weles 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

Answer 1

A)

got 100%

Answer 2

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

Explanation:

The quantitative traits are those whose inheritance pattern is the result of the action of multiple genes that act together with the environment. The distribution of quantitative traits in the population follows a bell-shaped curve, which is referred to as normal distribution or Gaussian distribution. These traits are 'quantitative' because they vary among individuals in the population to produce a continuous range of phenotypic values. Examples of quantitative traits include, among others, metabolic rate, height, and weight.
