Is it true or not?

Question

I've heard that if the temprature is higher in incubation the gender can turn out to be a male if the temp is lower it can be female. Is that true with birds or not? I just wanted to know if its true or not since I feel unsure.

If you missed some details the type of animal I was refering to were birds if you want me to be specific about the type of bird I was talking about pigeons.

Answer 1

that is not true at all. the sex is determined by the male. they will be what they are supposed to be. the tempeprature does not do a thing for the sex. generally the pigeons will have only 2 eggs. they will almost always be a m and 1 fefmale. everytime. i know this because i have raised and flown pigeons for quite a few years.

Answer 2

It's not true with chickens, although some old folklore books make this claim. These Old Wive's Tales date from before the days of embryology and DNA research (DNA was only discovered in the 1960s). Back then, people didn't know WHAT determined the sex of anything. We now know that the sex is determined by the sperm of the male (rooster). In any large batch of chicken eggs, you normally get about 50-50. However, I have heard that the temperature can affect the survival rate of the sperm of the two genders. (Roosters are supposed to be tougher). If this is true (and I have no scientific evidence for it, just rumor) then theoretically you could start out with 50-50 but kill off one sex or the other by having the wrong temp. If this happened, a person might assume that the chicks had all "turned into" roosters or hens in the eggs. But one must also take into account the eggs that DIDN'T hatch -- and rarely is there a 100% hatch, even under ideal conditions.

Answer 3

That is not true. The sex of the sperm that makes it's way into the egg for fertilization, is what the bird will turn out to be.As in all life forms. In some breeds of birds you can though, determine the sex of the babies sense some birds (like lutino and cinnamon cockatiels) are SEX LINKED GENES. Depending on all these factors with careful breeding, you can get the sexes you want if you work the color genetics right in the breed of birds you are working with. Here is a link to teach yourself about Genetics on Cockatiels, but the tempeture of the incubator has nothing what so ever to do with the SEX of the baby birds because it is not geneticlly realted to the making of the egg itself like the male and female are. Now if you want your babies to hatch one day apart, you can turn up the temp of the incubator up by one degree to make the babies inside the shell grow faster, but it wont have anything to do with what sex they turn out to be at all.

Answer 4

It is true depending on what animal you are talking about. Sex can be determined by temperature in certain species of reptiles. The temps are a fine range... if you specify the animal and species, I can give you more info.

Answer 5

Yes

Answer 6

I have heard that beofre but Im not to sure about it.

Answer 7

i have never heard of that before but it could be possible

Answer 8

I heard that before.

Answer 9

it can be true but u can never really tell

Answer 10

I doubt it
