How many pairs of sex chromosome in zygote of human?
A human zygote typically contains one pair of sex chromosomes, resulting in a total of 46 chromosomes. This pair determines the individual's sex: females have two X chromosomes (XX), and males have one X and one Y chromosome (XY).
How could a zygote be produced with an XYY karyotype?
An XYY zygote can be formed if a pair of sex chromosomes fails to separate during meiosis, so the gamete formed has both the X and Y chromosomes. This gamete would then meet the other gamete from the other cell that would contain a Y sex chromosome. The resulting zygote that is formed would have XYY sex chromosomes. This abnormalty where there is an extra chromosome or is missing a chromosome is called nondisjunction.
A sperm carrying a Y chromosome can produce a?
Male zygote if it fertilizes the female sex cell, ovum
What is a chance that a human zygote will receive one x and one y sex chromosome during fertilization?
The chance is 50%.
What is the order of fertilization sex cells meiosis zygote mitosis?
The order would be: Meiosis -> sex cells -> fertilization -> zygote -> mitosis Meiosis creates sex cells, called gametes, which combine during fertilization to create a zygote. The zygote then undergoes mitosis.
What two types of sperm result if nondisjunction of sex chromosomes occur during meiosis 1?
if nondisjunction occurs in meiosis 1 then the resultant sperms are XY carrying sperm n sperm without sex chromosome............ if XY carrying sperm fertilizes with normal X carrying ovum it results in XXY abnormal zygote if sperm without sex chromosome fertilizes with normal X carrying ovum it results in XO abnormal zygote

When is the the sex of a zygote determined?
In humans, the presence of a Y chromosome means the zygote will be male. So (normal) females will have XX - one X chromosome from each parent. (Normal) males will have XY - an X chromosome from their mother and a Y from their father.
What is the chance that a human zygote will receive one x and one y sex chromosomes during fertilization?
The chance is 50%.
How do chromosomes determine an individual's sex?
The female- or male- ness of the fertilized Ovum [Zygote] depends upon the X, or Y, 'component' of Chromosome Number 23 [the sex-chromosome] that is donated from the Male. All of the Female Chromosome Numbers 23 ARE XX.
What does the 23Rd chromosome represent?
The 23rd chromosome is the sex chromosome. It is either an X or Y (strictly male) chromosome. When the sperm and egg cells fuse, they combine into 46 chromosomes with either two X chromosomes or an XY pairing. If it is 2 X chromosomes, the zygote is a female. If it is an XY pairing, the zygote is a male.
A sperm carrying a Y chromosome can produce a?
Male zygote if it fertilizes the female sex cell, ovum
What is the chance that human zygote will receive one X and one Y sex chromosome during fertilization?
The chance is 50%.
What is a chance that a human zygote will receive one x and one y sex chromosome during fertilization?
The chance is 50%.
In humans a zygote will develop into a male it the?
Zygotes do not have a predetermined sex. The development of a zygote into a male or female is determined by the presence of specific sex chromosomes – XX typically leads to a female, while XY leads to a male. This determination occurs at fertilization when the sperm carrying either an X or a Y chromosome fuses with the egg.
What is the chance that a human zygote will receive one X and one Y sex chromosome during fertilization 100 percent 25 percent 75 percent 50 percent?
The chance that a human zygote will receive one X and one Y sex chromosome during fertilization is 50 percent. This is because an individual inherits one sex chromosome from each parent, with the father contributing either an X or a Y chromosome, and the mother contributing an X chromosome.
