In all Jewish communities the mtDNA is disproportionately more similar to that of local mtDNA than the YDNA is. MtDNA is that of the females. In theory it is passed on intact from mother to daughter in an unchanged form generation after generation. MtDNA stands for Mitochondrial DNA. Motochrondia help convert food matter into energy to sustain the cells. In theory, all the mtDNA you have is derived from your mother.
YDNA comes from the father.

In humans, each cell normally contains 23 pairs of chromosomes, for a total of 46. Twenty-two of these pairs, called autosomes, look the same in both males and females. The 23rd pair, the sex chromosomes, differ between males and females. Females have two copies of the X chromosome, while males have one X and one Y chromosome.
The fact that mtDNA is more similar to that of a local population than YDNA may mean either that:
a. More women from outside have been accepted into the community than males. In the case of Jews this is an historical possibility. Women go with the men and often may be more pliant and adaptable than the males are.
OR,
b. BOTH mtDNA and YDNA may actually reflect environmental influences at set times but the mtDNA changes much sooner and more often. This to our mind is the more likely scenario. ALL DNA ultimately is an outcome of environmental influence. A group of Jews sojourned in a region of Northern Italy or whose inhabitants later moved there. These Jews were subject to the same environmental influences and affected in the same way. They then moved into other Jewish communities and had a genetic, social, or physiological, or other advantage at a 'bottleneck' moment that caused them to predominate.

Abstract
http://dienekes.blogspot.co.il/
Publications that describe the composition of the human Y-DNA haplogroup in diffferent ethnic or linguistic groups and geographic regions provide no explicit explanation of the distribution of human paternal lineages in relation to specific ecological conditions. Our research attempts to address this topic for the Caucasus, a geographic region that encompasses a relatively small area but harbors high linguistic, ethnic, and Y-DNA haplogroup diversity. We genotyped 224 men that identified themselves as ethnic Georgian for 23 Y-chromosome short tandem-repeat markers and assigned them to their geographic places of origin. The genotyped data were supplemented with published data on haplogroup composition and location of other ethnic groups of the Caucasus. We used multivariate statistical methods to see if linguistics, climate, and landscape accounted for geographical diffferences in frequencies of the Y-DNA haplogroups G2, R1a, R1b, J1, and J2. The analysis showed significant associations of (1) G2 with wellforested mountains, (2) J2 with warm areas or poorly forested mountains, and (3) J1 with poorly forested mountains. R1b showed no association with environment. Haplogroups J1 and R1a were significantly associated with Daghestanian and Kipchak speakers, respectively, but the other haplogroups showed no such simple associations with languages. Climate and landscape in the context of competition over productive areas among diffferent paternal lineages, arriving in the Caucasus in diffferent times, have played an important role in shaping the present-day spatial distribution of patrilineages in the Caucasus. This spatial pattern had formed before linguistic subdivisions were finally shaped, probably in the Neolithic to Bronze Age. Later historical turmoil had little influence on the patrilineage composition and spatial distribution. Based on our results, the scenario of postglacial expansions of humans and their languages to the Caucasus from the Middle East, western Eurasia, and the East European Plain is plausible.See Also:
