2. FIGURE 1
Y chromosome haplogroups carrying gr/gr deletions. A simplified Y chromosome genealogy is shown at the left. The number of Y chromosomes carrying gr/gr deletions within each haplogroup and the associated phenotypes are indicated. The branch designation is described for the Y chromosomes carrying gr/gr deletions. The Y chromosome lineage E3b2 is a YAP-positive lineage that presents in approximately 42% of North African populations. 1Father of one child, semen parameters are unknown. 2A second semen analysis taken 1 year later revealed a sperm count of 46 × 106/mL.
