Question

The height of a type of plant is a normal distribution. Some plants are tall and some are short, but most are in between. What is mostly likely true about this trait?
A.) being short is a recessive trait
B.) height is controlled by one gene
C.) several different genes control height
D.) the height is a Mendelian trait 

Answer 1

Answer: The correct answer is- C.) several different genes control height.

As per the information given in the question, there are different plant heights in the population that is tall, short, and heights in between these two.

This indicates that this trait is controlled by many different genes ( as many different phenotype are seen in the population).

This situation corresponds to polygenic inheritance, which means that a particular characteristic of an organism is controlled by more than one two genes ( such as skin color, height in human beings)

Answer 2

The answer would be C, several different genes control height.
