Question

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

• A. pseudoalleles
• B. multiple alleles
• C. part of the same gene
• D. different genes

Answer 1

The correct option is A pseudoalleles

Two genes are said to be in cis position if the dominant alleles of both genes are on the same chromatid of a pair of homologous chromosomes.

Two genes are in trans position if the dominant alleles of both genes are on different chromatids of a pair of homologous chromosomes.

Pseudoallelism is a state in which two closely linked genes produce identical phenotypes weather the genetic loci are in cis or trans position.
