Pedigree Query

Watching a documentary I just learned that a female Komodo dragon has the very unique ability to produce fertilized eggs (from herself alone) that will produce, let's say, 5 male Komodo dragon that later on will cross with their own mother and reproduce male and female Komodo dragons in the second generation. You may be asking what is the importance of that. Well the Komodo islands (many islands) is a volcanic zone and on ocassions a female individual may be stuck on an island without the possibility of meeting another Komodo dragon (in this case a male) in order to reproduce. This is a very important clue for us to understand on how extreme nature can become in order to assure the survival of species. Note that all of this is achieved via the female lineage.

Now extrapolating a little, my question is, what lessons can we learn about the role of the female lineage ON THE TRANSMISSION OF COAT COLOR INFLUENCE IN GENERAL?

Comments, opinions, theories?

From
http://en.wikipedia.org/wiki/Parthenogenesis

Go to section: Reptiles

First paragraph:
Komodo Dragon, Varanus komodoensis, is confirmed to be able to reproduce naturally by parthenogenesis…….


Fifth paragraph:
Recently, the Komodo dragon, which normally reproduces sexually, was found also to be able to reproduce asexually by parthenogenesis……

……Parthenogenesis may also occur naturally when males and females are both present, which might explain why the wild Komodo dragon population is approximately 75 percent male.

JORGE, you are a hoot....I LOVE your dedication.....

The Komodo Dragon is a fantastic.....but scarrry to me.... animal...they bite their pray....inject some HORRID bacterial slim and let it take it's course....stalk that animal.....wait until it dies...and GOES TO TOWN....


I think what they can do is fantastic.....I'd only known of the EARTHWORM being able to "do themselves" and end up pregnant

As far as colors of horse coats....THE Oldest color is one of the best...DUNN and all their factors....gotta love that.......It has taken sometime, but their coats and bodies and temperaments have changed.....NOW HOW IT changed?????? I have no idea......Red is SO dominate in the horse world.....I can SEE RED in this mare's coat....(LOOKIE HOW CUTE THAT FOAL IS....)




You will have to tell me...I teach Pre-Schoolers and Read Mother Goose...

To me, one lesson to be learned is that the female lineage is more crucial than the male lineage because when nature wants to assure the survival of one species from extinction the female has the supremacy. Someone may ask: well that's obvious for all creature are born through a female rather than through a male. True, but the Komodo dragon example is as simple as one can obtain. This makes me ponder on the importance of female lineage in general as applied to the appearance of any unknown phenotypical pattern one may study. This as a rule of thumb. Certainly, nature is an open book for all of us to learn from.

This thread is not about those scary creatures known as Komodo Dragons but about the medular importance of the female line.

Can you cite other instances where the importance of the female lineage
reveals us something really special in terms of genetics and rare traits.

Not about KD's. Well, just in case...

UHHHHH THE HUMAN RACE

MAN, this place it TOUGH.....I thought for sure I'd get at lease an AMEN or 2...

Haha... I hadn't even seen your post because I'd stopped reading the thread.

This old “Komodo Dragon” topic makes me remember its pertinency
with this 2011 topic: “Fantastic example of a cropout”
which can be read at:

Very rare specimen. See for yourself the video:

Not to even mention this one:

More on the effect of environmental issues on coat color transmission!

A new hybrid shark has been discovered in Australia. It is the result of the mating between two sharks: one coming from salt water and the other from non-salt water. Apparently the resulting little sharks are being affected in their phenotypes. Seems like some sort of repetition of the Komodo phenomenom but of course with different variables. It looks like global changes are having a huge impact on phenotypes. Given this scenario expect new phenotypical variations in horses.

personally, I think that one will find that there are many many species, that are in fact a hybridised species..
