Hi  guys,
I want to ask that Why Google should give first preference on Dofollow list rather than of Nofollow list?
Any thoughts?

Preference? Care to tell where you read that?

Google crawls both types of links but excludes "nofollow" from the link graph (in the sense you don't get backlinking credit but nevertheless you get referral traffic from them).

I also do not know about it but it is from starting Google always give preference to dofollow links.

no follow links are quantity
do follow links are quality..

hi.
Each search engine has their own rules and policies. Google follows only dofollow links to drive more traffic but no follow links do not have any links so they will give less traffic. No follow links are used by Google.

Google always prefer dofollow links because they drive much traffic. Do follow links are the good quality links.

No only Google but Yahoo & Bing does also like Dofollow links.

Everybody likes quality material not a quantity. Google is perfect search engine that's why it is so popular among us, that's why Google preferring always quality links, and do follow links are quality links when you connect with do follow sites defiantly you get quality backlinks which is more important to improve your website reputation in search engine. 

But when you practice advanced linkbuilding, you have to make sure that you have nofollow links as well. Otherwise it looks to obvious and google will penalize you!

Well I think these are tags no follow means Google will not follow and dofollow means Google will follow that is why Google give preference to dofollow.

Hi,
Google is a search engine and every search engine having its own program (a software program) to judge or crawl a website and so as links. The Google bot works on it and didn't crawl the no-follow links. Other search engines didn't follow the concept of do-follow and no-follow links.

To calculate value of backlinks,google has divide backlinks in two part:

(1)Dofollow=Traffic+Improve PR+Improve SERP + Search Engine Like
(2)Nofollow=Only Get Traffic

It's very simple when request the search engines to follow the link "DoFollow", obviously it will crawl over the link; and when we say don't follow the link "NoFollow" it will not crawl over the link. Why only Google, each and every search engine will do this. 
It depends completely on the site owner. 

Every search engine like "Dofollow" links and they are giving importance accordingly.We can take following advantages with help of dofollow:

*Increase PR
*Improve SERP
*Get Traffic

Dofollow attribute link would help you in following:

* Increase SERP
* Improve Page Rank
* Get Traffic

Yes i agree. Do follow links are so helpful to get high PR. Its very important use dofollow sites

Do follow links are very good for getting backlinks.Google crawler always check for the do follow links.
Google crawler discard no follow link.But it is not any rule that it will not follow do follow link.

Obviously any kind of link is good, but Google does seem to fasvour the dofollow links. You can use SEOQuake to find the difference if you want

No follow links also help as you have written above.

Google just ignores no-follow links.
Only dofollow links will help you for your SERP and get a higher PR
