Question

Reciprocal cross is made to determine it: 

Options

• the trait is inherited as dominant

• the trait is inherited as recessive

• sex has any role in dominance recessive relationship

• the trait shows codominance

Answer 1

sex has any role in dominance recessive relationship

Explanation:

A reciprocal cross is performed by reversing the sexes of the parents with respect to a trait (i.e., parent A as female and parent B as male in one cross, then parent A as male and parent B as female in the reciprocal cross). This helps to determine whether the inheritance of a trait is influenced by the sex of the parent, such as in sex-linked traits. Thus, it reveals if sex has any role in the dominance-recessive relationship of that trait.
