What is an allele? trait form that is hidden by a dominant gene identical copies of two different genes trait form that is displayed by recessive genes one of different forms of the same gene

one of different forms of the same gene.

Explanation:

Mendelian ‘factor’ later called genes. The gene is responsible for the inheritance of traits or characteristics. The genes for each present in different forms. Each organism have two copies of each gene for a trait. For example, the shape of a seed is determined by the gene R its allele will be r. Thus, alternative forms of a same gene is called allele. Round seed is dominant have genes RR or Rr. Wrinkled seed is recessive feature  will be rr.  

explanation:

the universal gravitation equation. since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. if the mass of one of the objects is doubled, then the force of gravity between them is doubled.
