Answer:
GOOD MORNING
Morgan carried out dilybird crosses in drosophila to study genes that showed sex linkage. He hybridised yellow-bodied white eyed females to brown red eyes and carried out the study to
F2
and noticed that the
F2
phenotype ratio deviated from the
9:3:3:1
Mendel dihybrid
F2
phonotypic ratio. Morgan used the genes that were both located on x-chromosome and summed up that the proportion of parental gene combinations is much higher than the non-parental one in case of physical association of genes or linkage of two genes.
