The reason the chance of a zygote being a male of female is the same is due to simple genetics. Females only possess the X chromosome while males posses both an X chromosome and a Y chromosome. Since females only have an X chromosome they can only "give" an X chromosome while a male may give either an X or Y chromosome.
Zygotes are diploid, meaning they contain two sets of chromosomes (one set from each parent). This is because a zygote is formed by the fusion of a haploid egg cell and a haploid sperm cell during fertilization.
An ovum will have an X chromosome regardless, but a sperm has a 50% chance of having either an X or a Y chromosome, so there's a 50% chance a zygote will be XY (male) and 50% that it will be XX (female).
No, most cats are not female. The gender distribution of cats is fairly equal, with approximately half being male and half being female.
The embryo receives half of its chromosomes from the female's egg and half from the male's sperm. This genetic material combines to form the unique set of DNA that determines the embryo's traits and characteristics.
Zygotes get half of there DNA from both the father and mother because during fertilization, only a haploid number of chromosomes is released for fussion, i.e 23. When both parents releases 23 each, it makes up 46.
there are half the chance of a female and half the chance of male so probabilty in both cases is 1/2
50%, or half. Therefore, there is an equal chance that the offspring will be female.
Human genes have a probability of 0.5, or 50% of being male or female. Genes are just naturally designed this way.

It has half of whatever the organism's regular cells have.
There is sex chromosome in both male and female. Female has got XX chromosome. Man has got XY chromosome in the nucleus. So when you get an ovum, all of them have got X chromosome in them. When sperm form, you get half the sperms with X chromosome and half the chromosome have Y chromosome in them. So there are fifty percent sperms that are mean to be males and fifty percent chromosomes that are meant to be females. Which sperm will enter the ovum can not be known. So there are fifty fifty percent chances of baby becoming male or female.

If I understand the question correctly, you have a calico female that you want to produce another calico? The best suited tom would be black and white, preferably with lots of white. The result is around half of the female offspring will be calico, half black and white, with a slight chance of one having brown in its coat. Alternatively you can use a ginger and white tom, with half of the females being ginger and white, although there is a greater chance of the other half being tortoiseshell-tabbies or brown, ginger and white.
theres a half and half chance it will and theres a half and half chance it wont
Half Chance Iron Bridge was created in 1880.

The result of the spin will be red one half, or fifty percent, of the time. The other one half, or fifty percent, black will come up. In other words there is a fifty percent chance it will be red and a fifty percent chance that it will not. Hence fifty-fifty. With an actual roulette wheel, you have less than a fifty-fifty chance of spinning red.
