The sex of mammals is determined by their combination of sex chromosomes. In most mammals, females have two X chromosomes (XX) and males have one X and one Y chromosome (XY). The presence or absence of a Y chromosome is the primary factor that determines whether an individual will develop as male or female.

What does sex determination mean in farm animals?
the same as people. Sometimes it is difficult to figure out what gender the animal is especially when they are young. For example, chickens and ducks etc. For mammals it is easier but it still has to be determined. That is all sex determination is, checking if they are male or female.
How is the sex of a crocodile determined?
The sex of a crocodile is typically determined by the temperature at which the eggs are incubated. In general, warmer temperatures during incubation result in more males, while cooler temperatures result in more females. This phenomenon is known as temperature-dependent sex determination.
How is sex determined in most ants and bees?
In most ants and bees, sex is determined by the fertilization of eggs. Fertilized eggs develop into females, while unfertilized eggs develop into males. This type of sex determination system is known as haplodiploidy.
In what condition is crocodile sex formed?
The sex of developing crocodilians is determined by the incubation temperature of the eggs. This means crocodilians do not have genetic sex determination, but instead have a form of environmental sex determination which is based upon the temperature embryos are subjected to early in their development. Crocodile embryos do not have sex chromosomes, and unlike humans sex is not determined genetically. Sex is determined by temperature, with males produced at around 31.6 °C, and females produced at slightly lower and higher temperatures. The average incubation period is around 80 days, and also is dependent upon temperature.
What is the name of the male sex cell in a rabbit?
A Sperm Cell as in most mammals like humans.
Is the sex of the offspring determined by the female parents chromosomes?
No, the sex of the offspring is determined by the combination of chromosomes from both parents. In mammals, females have two X chromosomes (XX) while males have one X and one Y chromosome (XY). The sex of the offspring is determined by whether the father contributes an X or Y chromosome during fertilization.
What is the difference between 'sex-liked' and 'sex-determined'?
Sex-liked means liking sex and sex determined is the resolution to have sex.
Why do male mammals have nipples?
Male mammals have nipples because during early development in the womb, all embryos follow a similar blueprint before sexual differentiation occurs. Nipples are formed before the sex of the embryo is determined, so both male and female mammals develop them.
How does the protein controls the sex of a developing embryo?
Proteins do not directly control the sex of a developing embryo. The sex of an embryo is determined by the combination of sex chromosomes inherited from the parents. In mammals, the presence of a Y chromosome typically leads to the development of a male, while its absence results in a female.
Why do male cats have nipples?
Well HELLO! why wouldn't they? Mammals have nipples.
How sex of embryo can be determined?
By taking the DNA of the embryo, putting it through some tests and coming out with results on whether it's a female (XX chromosomes) or a male (XY chromosomes). These chromosomes are the same in terms of sex selection for all mammals.
What is the sex chromosome in man?
For mammals, sperm.
Is the sex of a second child determined by the sex of the first?
No, the sex of the second child is determined independently of the sex of the first child. The chances of having a boy or a girl are generally close to 50/50 regardless of the sex of any previous siblings.
How early is your sex determined?
conception
What causes a chicken to be a male or female?
The sex of a chicken is determined by genes when the egg is fertilized. It should be a 50/50 chance of male or female. And in the case of chickens it is the females that have the xy gene that determine sex and males that carry the xx gene, this is opposite of mammals where males with their xy gene determine the sex of the offspring.
What does sex determination mean in farm animals?

How is the sex of an individual determined?
Scientists do not determine the sex of a fetus. Science does, but scientists do not.
