The most likely explanation for a continuous trait, like plant height, is that it is controlled by several different genes. Option C is correct
Given that the feature is described as having a normal distribution and a range of heights, it is most likely polygenic, meaning that it is regulated by several genes.
A continuous range of phenotypes results from the interaction of several genetic and environmental variables on the characteristic in a normal distribution.
Therefore, Several different genes control height
The complete option are :
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
