Two heterozygous parents are crossed. If the two loci are linked what would be the distribution of phenotypic features in `F_1`, generation for a dihybrid cross?

Text Solution

Verified by Experts

If the two loci in parents are completely linked, there would be no segregation.
= The `F_1` generation will exhibit parental characters only.
= But, if the two loci are incompletely linked then segregation would occur partly and the `F_1` generation will exhibit both parental and recombinant characteristics, but the recombinant will be in a very small proportion.

= Only two types of gametes will be produced from each parent as the two loci are linked.
