Fifty percent. All eggs contain an X chromosome. Sperm are either X or Y, and are usually present in equal numbers.

The chance is 50%.
Sex-linked diseases are more likely to affect sons of female carriers because why?
The son would automatically get the Y chromosome from the father. The son's X chromosome has to come from his mother. Females are XX, so he has a fifty-fifty chance of receiving the disease carrying gene. If he receives the disease carrying gene he will have the disease, if he doesn't then he will neither have the disease nor be a carrier. A daughter has to receive one X chromosome from her father and one from her mother. If the father doesn't have the disease, then the daughter cannot have it. If the mother is a carrier, then she has a fifty-fifty chance of being a carrier.
What fact expains why half of kids are boys and half are girls?
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).
What is it called when sperm and eggs are released into sea water and chance contact results in fertilization?
external sexual
Why is there the chance that half of the zygotes will be female and the other half will be male?
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.

The chance is 50%.
What is the chance that a human zygot will receive one x and one y sex cromosome during fertilization?
The mother will always contribute an X chromosome. So, assuming the father's X and Y chromosomes are equally likely, the answer is 1/2.
What are morphological scoring systems?
>9%=good chance of fertilization 4-9%=fair chance of fertilization 0-3%=poor chance of fertilization
Is it 40 percent of the area that will receive rain if there is a 40 percent chance of rain?
No, 40% chance of rain is How Likely it is to rain for that day,or week. Not Area. LOL
Why is there is a 50 percent chance a new born baby will be female?
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.
Why Males having a greater chance of hemophilia?
Hemophilia occurs in the X chromosome, and males are the genders that have the X chromosome.
What is the chance an X chromosome is inherited from a mother?
A female has the sex chromosomes XX. Therefore they will always pass an X chromosome on to their children.
What are the 2 types of fertilizers?
Internal fertilization and external fertilizationinternal means When the fusion of the male and female gamete occurs within the female genital tract it is called internal fertilization. This type of fertilization occurs in all terrestrial animals both oviparous and viviparous. Reptiles, Birds and mammals show internal fertilization external fertilizationThe fusiri of the gametes occurs outside the body of the animal and is common in aquatic animals. In bony fishes, frogs, echinoderms the sperms and ova are released into the water and their union occurs by Chromosome number of few chance. Since fertilization occurs outside the body of the animal externally, this method is called external fertilization.
