The key reason for this lack of knowledge is the current assumption that performance of sperm produced by a male is under diploid control ( 4– 6), a notion that is further supported by the apparent lack of association between the phenotypic variation among sib sperm and their genetic content ( 7, 8). Sperm within an ejaculate exhibit remarkable phenotypic variation ( 1), but little is known about the causes and consequences of such variation and selection among sperm produced by one male. Our findings clearly link within-ejaculate variation in sperm phenotype to offspring fitness and sperm genotype in a vertebrate and have major implications for adaptive evolution. Sperm pools selected by motile phenotypes differed genetically at numerous sites throughout the genome. The effect on embryo viability was carried over into the second generation without further selection and was equally strong in both sexes. Longer-lived sperm sired embryos with increased survival and a reduced number of apoptotic cells, and adult male offspring exhibited higher fitness. Using the zebrafish Danio rerio, we show that selection on phenotypic variation among intact fertile sperm within an ejaculate affects offspring fitness. Although haploid selection is well established in plants, current dogma assumes that in animals, intact fertile sperm within a single ejaculate are equivalent at siring viable offspring. The occurrence of selection during the haploid phase can have far-reaching consequences for fundamental evolutionary processes including the rate of adaptation, the extent of inbreeding depression, and the load of deleterious mutations, as well as for applied research into fertilization technology.

Take video snapshots at full resolution.Compact mode: a small, always-on-top window.Channel subscriptions without using a YouTube account.Minitube focuses on a pleasing overall experience, not on having tons of features. continious material on that subject - Simples! well worth it! Murtha Piggott but thats the clever thing - it is! choose you search subject and off you go. After installing it, and running it, I 'get' the purpose, and would gladly recommend it Will, Stormfront Tech Allan CampbellĪt first, I was skeptical of the utility of Minitube.

Great app! Was hesitant to buy, but it did what it said and was exactly what I was after! James Bedford

My dad has even told me that this is without a doubt the program that he spends most of his time on (he does other things, but this is almost constantly open in another space playing some traditional Italian music or 1930s comedies). My 4 years old is a big fan of Minitube -) RobertoĪ clean, modern interface and no requirement of third party plug-ins makes this program an invaluable tool Tomaaato She really LOVES television, so I think she will like using Minitube as Minitube would be a terrific way to introduce her to the world of Internet I will be installing a copy of Minitube om my Mother's PC. Videos more like the experience of watching television, and more enjoyable. I believe you succeeded well in your goal to make watching It's been a long time since I found a program that works out of the box and does what the blurb says it should. It sort of subtly changes your perception of what's going on.

Minitube allows you to search for videos in a breeze without any complications in between. It's a terrific app that eliminates the need to poke around YouTube's Web site and navigate through a sea of ads, comments, and related videos you may not care about. Makes it impossible to stop watching videos when what you should be doing is writing that program's review. If you're looking for a way to check out YouTube clips outside the browser, it's a really elegant solution Lifehacker

My kids just love this app! Easy to use and a great interface.
