What is the chance that a human zygote will receive one x and one y sex chromosomes during fertilization?
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.
Explain why a woman carrying a gene for hemophlia can produce hemophilic sons when she is mated with a normal male?
A woman carrying a gene for hemophilia is typically a carrier with one X chromosome carrying the hemophilia gene and one X chromosome carrying the normal gene. When she is mated with a normal male who has one X chromosome and one Y chromosome, there is a 50% chance that the son will inherit the X chromosome carrying the hemophilia gene from the mother. Since males have only one X chromosome, if they inherit the hemophilia gene, they will express the disorder.
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.
What is it called when sperm and eggs are released into sea water and chance contact results in fertilization?
This process is known as external fertilization. It is a method of reproduction where gametes (sperm and eggs) are released into the environment, usually water, and fertilization occurs outside of the organism's body. This is common in aquatic species like fish and amphibians.

What is the chance that a zygote will receive one x chromosome and one y chromosome?

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
What is the probablilty that a human sperm cell will carry an X chromosome?
The male gamete is comprised, on average, of 50% of the X chromosome and 50% of the Y chromosome.
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.
