Question

When two genetic loci produce identical phenotypes in cis and trans position, they are considered to be

(a) pseudoalleles 

(b) different genes 

(c) multiple alleles 

(d) parts of same gene

Answer 1

Correct option (a) pseudoalleles 

Explanation

Pseudoalleles are closely placed genes producing related phenotypic effect which is distinguishable only through a rare crossing over, e.g. dominant star and recessive asteroid eye traits in Drosophila.
