a. being tall is a dominant trait.
b. there are only two alleles for height.
c. it is a mendelian trait.
d. it is controlled by several different genes.

Correct answer choice is :

Measure the heights of a large unit of adult men and the numbers will follow a standard distribution. But height is not a simple property. There are various genetic and environmental determinants that affect height. The Cheyenne people of North America were among the tallest in the world, with a medium male height of about 5 feet 10 inches. Steckel puts this down to the availability of protein in the form of buffalo.

c) 50% there are four chromosomes. after crossing over, 2 of the four have been changed. that means any gamete has a 2 in 4 chance or 50% chance of receiving the mutated chromosome.
