now I have your attention .if a pair of stock-birds produce mainly cocks that win ,which would you say was the prominent parent ??

[just ask me]

hen

 

and if i get 2 cocks in the one nest off certain hens there usually 2 good ones in the nest

from experience , have you noticed if the hen that produces good racing cocks , produces hens in later years which aren't as strong racing wise ??

would u say the same about 2 hens in a nest Jam? and think the cock is dominant?

interesting thread Andy.....for some reason i seem to get a lot of double sexed nests...would like to hear more thoughts on this.

they are questions once asked Mick , should stay with us once we get the answers. things that otherwise can take decades to learn.

as i only race old cocks im really hoping 2 cocks in the nest from 1 or 2 hens

 

the other way around i have not kept such a close eye on but some of my best breeding hens have never thrown 2 hens to the best of my memory even when switched around with other cocks i rarely leave pairs together

 

if you get the book by vansalen it goes into depth on chromosomes etc its very interesting

 

i myself just try to put the best to the best and hope for a bit of luck

 

if im right the hen and im most probably not id have to read up on it again the sex of youngsters is down to the hen

 

is it down to the timing of the mating im not sure

as i dont race old hens andy i couldn't really answer the question

[Guest IB]

I'm thinking that there are two different aspects in this question.

 

(1) sex chromosomes - Yes. Birds (Z,W) are the opposite of mammals (X,Y), and it's the hen that carries the single male chromosome that determines the youngster will be a cock.

 

(2)average of sexes produced - No. Throughout the life of any breeding pair, the offspring will be 50% male and 50% female. Some nests cock & hen, some 2 x cocks, some 2 x hens, but average is still same.

Thanks Jam, ill look out for the book

[just ask me]

Thanks Jam, ill look out for the book

 

 

victor van salen he wrote the masters of breeding and racing also champions reveal there untold secrets

 

both are the best books ive read on the sport

 

you wont pick them up cheap as there not published any more

 

but a must read

I'm sure it's the hens that determine sex in birds,ie carry the x or Y chromosome.its the opposite in mammals.

It's always the same odds to be male,female or male and female I can't think of any other factors,unless there's a lethal gene in there that selects cocks only.

Very interesting topic

Cracking Q Andy, i think most time would be hen

But does that not change if its a inbred family orginate from female strain ????champian.

It's the cocks only the cocks have xx chromosome hens only have x chromosome all other characteristics are shared 50/50 but about a 1 in 24 chance of breeding like for like as near as to the cock or the hen you want to breed back to with the gene permetation between the cock and hen the other 23 wont all be bad birds if your breeding best to best but they wont all be good

[Guest IB]

It's quite simple maths for the first generation, 50% chromosomes come from the hen, and 50% come from the cock.

 

But it is worse than a lottery as far as what 'characteristics'[genes] are passed on, and from which lineages those genes originated. Remember that 50% applies to each generation, backwards and forwards.

 

There's 40 pairs of chromosomes. Each single strand is paired in a specific way with a partner, and each has hundreds? of genes, themselves arranged in a specific way. The paired chromosomes split into 40 single strands to form egg or sperm cells. When they split, those 40 strands also split, and the arrangement of genes can change both within each strand, and between strands.

 

Therefore there are many different combinations available to be passed into each egg or sperm cell. The question now is 'will this combination click' with other combination coming from the other partner in the mating. Answers on a postcard.

If you look at Race Horses I think you can see the answer to your question. All race horses are sired by top winning fathers. So the variability must be with the mares. A good way you can select yearling horses is to select those from mares that have previously produced winners. When you look into the dams of winners you will see that some mares can pass on this ability whereas other can not. I think although mares pass their genes on to their offspring their major contribution to their young is vigorous good health.

So in answer to your question it is likely that the cock has provided the winning genes but it will be the hen that has provided the health and vigour that all athletes must have to become special. It is fairly easy to test both sexes by using the cock in a bull system with say 10 hens and changing the hen's partner for a cock of equal ability.

There is no need to theorise about something like this because you can test these individuals and then accept the evidence of your eyes.

have had some very good answers to this question , and some very good information via PM,s . any other views appreciated.

[blucock]

Quite a few sires in horse racing have been either poor race horses with top pedigrees or unraced. The most famous ones have been of course champion or prodigious racehorses but of course statistics would be tempered by the fact that there are many more offspring taken from successful horses than poor ones so increasing the chances of winners coming from them

 

As a human parallel I have two sons and none of them become very bright but my twin brother has twelve sons and four of them become MENSA members - he is then a better sire than me .... or is he?

 

[Kyleakin Lofts]

I never knew you had 2 sons Barry and being a Mensa member, I didn't realise that Colin was my dad!!!

Funny old things are statements of so called truth.
