Haplogroup Q-M242 is primarily defined by the M346 single-nucleotide polymorphism (SNP).
Answer: False
While M346 is a significant SNP in the lineage leading to Haplogroup Q-M242, the primary defining mutation for Haplogroup Q-M242 itself is the M242 SNP, as indicated by its nomenclature and confirmed in genetic studies. M346 is an ancestral haplogroup marker.
Haplogroup Q-M242 is one of the two major subclades branching from Haplogroup P1.
Answer: True
Haplogroup P1 is the ancestral haplogroup from which two major Y-DNA haplogroups diverged: Haplogroup Q-M242 and Haplogroup R-M207. Both are significant in terms of global distribution and population genetics.
The M242 SNP, defining Haplogroup Q-M242, was discovered by Luigi Cavalli-Sforza and colleagues.
Answer: False
The M242 SNP was discovered by Mark Seielstad and colleagues in 2003, not Luigi Cavalli-Sforza and his team.
Q1/Q-L472 and Q2/Q-L275 are the two primary subclades of Haplogroup Q-M242.
Answer: True
Haplogroup Q-M242 is characterized by two main subclades: Q1 (which includes Q-L472 and Q-MEH2) and Q2 (which includes Q-L275). These represent the primary branches of this haplogroup.
The 'Q*' designation in distribution data refers to samples belonging to Haplogroup Q that do not fit into defined subclades.
Answer: True
The 'Q*' designation is typically used in population genetics studies to denote samples belonging to Haplogroup Q but which do not match any of the currently defined, specific subclades. This often occurs in regions with limited detailed analysis or unique genetic variations.
The Y Chromosome Consortium (YCC) is one of the main sources for Haplogroup Q-M242 phylogenetic trees.
Answer: True
