Two hetrozgous parents (AaBb) are crossed if the two local are completely linked (AB/ab) what would be the distribution of phenotypic features in resulting generation of test cross ?

Text Solution

Verified by Experts

If two loci are linked (i.e, genes are located closely on the same chromosome. There would be no segregation of alleles/traits due to absence of crossing over.

`:.` phenotypic ratio `= 1:1`
