Japanese korean genetic relationship between homologous chromosomes

Homologous recombination (HR) between parental chromosomes PHYTOENE SYNTHASE (PSY1) gene results in yellow fruits with wild type. Pairing and recombination of homologous chromosomes are essential for The sme2 gene encodes noncoding polyadenylated RNAs, meiRNA-S and . ectopic association persisted from 5 to 30 min and then was resolved during the .. This work was supported by KAKENHI grants from MEXT of Japan to D.-Q.D., T.H. The people of Japan could derive genetically from either the Yayoi or the have been studying the presence of a particular gene on the Y-chromosome called They found that the YAP gene does not occur among men from Korea or Taiwan.

But his data has not loaded…. The former was not of great interest to me, as my family is large enough that I had a good sense of what we were at risk for. It also told me I was at more risk for ailments which are not known in my family. And, it told me I was at less risk for ailments common across my extended pedigree.

Finally, it told me I was at less risk for ailments not common across my pedigree. You get the picture. In regards to ancestry, I have received some value.

My involvement in the Harappa Ancestry Project is more about understanding regional patterns of variation, than that of my own family. My male sibling and my father. Of each gene my father contributes one copy on the autosome. In contrast, my sister has more segments shared. The relationship to our mother is also as expected. Below are the screenshots from family inheritance comparing the three siblings in terms of our genomes.

Remember that half-identical light blue has half the weight as full-identical dark blue.

The fine-scale genetic structure and evolution of the Japanese population

I share about the same length of segments that are half-identical to both RS1 and RS2, 2. But, while I have 0. RS1 and RS2 have much less in common than I do with either of them. It may be that most of the Bangladeshis in the database are from my own immediate family!

Under one scenario the Yayoi largely replaced the Jomon. Under an alternate scenario the Yayoi brought the culture which was assimulated by the Jomon and the genes of the Yayoi are lost in the ocean of Jomon genes. In between these scenarios is the one in which the Japanese people are a mixture of the Yayoi and the Jomon.

To the outside world the answer to which of these scenarios occurred is only mildly interesting, but to the Japanese themselves the answer is psychologically quite important. At this point it must be noted that there has survived in Japan a people and culture of a hunting-and-gathering society called the Ainu.

Whether the Ainu are the survivors of the Jomon people or not is a question still to be decided.

The fine-scale genetic structure and evolution of the Japanese population

Now the Ainu survive only on the northern island of Hokkaido but a few centuries ago they were an important element of the population of the main island of Honshu. The Ainu differ from the Japanese in that they have lighter skin and more body hairy.

They were frequently referred to as the hairy Ainu. To settle the question genetic researchers have been studying the presence of a particular gene on the Y-chromosome called the Y Alu polymorphic element YAP. It developed in relatively recent history and so not all males have this gene.

It occurs among Japanese men and then only with a special regional distribution. In the central part of Japan the YAP gene does not occur. This suggests that the YAP gene developed among the Jomon and was passed on to the Yayoi only were there was racial mixing.
