Question

Each trait of a plant is determined by _____. an allele one gene a pair of genes one dominant gene

Answer 1

Each trait of a plant is determined by a pair of genes.

Answer 2

Ans.

A trait is defined as a distinguishable characteristic or quality of an individual, such as plant height, flower color, or eye color. All traits show genetic basis as each trait of an individual is determined by a pair of genes inherited from its parent (one gene from mother and one from father).  

Thus, the correct answer is 'a pair of gene.'
