In the Human Genome Project, researchers have collectedlinkage data from many crosses in which the male washeterozygous for molecular markers and many crosses wherethe female was heterozygous for the markers. The distancebetween the same two markers, computed in map units, isdifferent between males and females. In other words, thelinkage maps for human males and females are not the same.Propose an explanation for this discrepancy. Do you think thesizes of chromosomes (excluding the Y chromosome) in humanmales and females are different? How could physical mappingresolve this discrepancy?

Genome annotation

The technique of linking biological information to genome sequences is termed genome annotation. Gene annotation is the method of identifying gene locations and coding sections. It helps us understand what these genes are doing in the body through establishing structural characteristics and linking them to the actions of various proteins.
