What syndrome is inherited when an egg carrying two x chromosomesis fertilized by a sperm carrying one y chromosome?
Klinefelter's Syndrome results when a person has XXY chromosomes (an extra X chromosome). The main effects of this are hypogonadism and reduced fertility.
What syndrome is inherited when an egg carrying two X chromosomes is fertilized by a sperm?
Klinefelter's Syndrome results if a person has XXY (an extra X chromosome). The main effects are hypogonadism and reduced fertility.
When is the baby sex determined?
It is the sperm from the male determines the sex of the child. Half of the sperms contain the Y chromosome and half the sperms contain the X chromosomes. Ovum from the female always contain the X chromosome. When the sperm with Y chromosome fertilize the ovum, the sex of the child becomes male. When the sperm with X chromosome fertilize the ovum the sex of the child becomes female. The females are wrongly blamed for the birth of female child in some countries.
The Smiths have four children all girls Their fifth child is a boy Why did this change occur?
Because one of Mr. Smith's sperm, carrying a Y chromosome, fertilized his wife's egg.
Is the mitochondrial DNA in a baby more like the mitochondrial DNA from his mother's mother or the mitochondrial DNA from his father's mother?
It is exactly like the mothers (except for some possible random mutations). The mother's egg has all of the cytoplasmic components inside it. The sperm only carries DNA. So mitochondria are maternally inherited. While the sperm does contain mitochondria in its tail, only the DNA from the head are transported into the ovum. The DNA of the child consists of half the genetics of the mother and half the genetics of the father. This is because the sperm carries 22 chromosomes and an extra sex chromosome (X or Y). The egg inside the mother also carries 22 chromosomes and a sex chromosome (X or X). When these meet we get 22 sets of chromosomes and a set of sex chromosome (X,Y or X,X) which determines the gender of the child. However, if the mother or the father is carrying an extra 21st chromosome and for example, the child receives 2 21st chromosomes from the father and 1 from the mother, they now have 3 21st chromosomes which can lead to the child being born with downs syndrome.

What are the X and Y chromosomes?
Everybody has 23 pairs of chromosomes, half they get from their mother and half from their father. The 23rd chromosome you have contains the information of what sex you are. If you are a girl you will have a X chromosome from your mother and and X chromosome from you father. If you are a boy it means you will have a X chromosome from your mother and a Y chromosome from your father. When a sperm cell fertilises an egg the sperm will either be carrying the X chromosome from the male or a Y. If the sperm is carrying a X it will pair with the X chromosome from the mother making the baby a girl. If the sperm is carrying a Y chromosome it will pair with the X chromosome from the mother making the baby a boy! This means it is all down to the father whether the baby is a boy or a girl.
When is the baby sex determined?
It is the sperm from the male determines the sex of the child. Half of the sperms contain the Y chromosome and half the sperms contain the X chromosomes. Ovum from the female always contain the X chromosome. When the sperm with Y chromosome fertilize the ovum, the sex of the child becomes male. When the sperm with X chromosome fertilize the ovum the sex of the child becomes female. The females are wrongly blamed for the birth of female child in some countries.
Which trait will a male exhibit if he carries a recessive allele on the X chromosome?
A male carrying a recessive allele on the X chromosome will exhibit the recessive trait. This is because the Y chromosome generally does not have matching genes for the X chromosome, unlike the other 22 pairs if chromosomes in the nucleus.
The Smiths have four children all girls Their fifth child is a boy Why did this change occur?
Because one of Mr. Smith's sperm, carrying a Y chromosome, fertilized his wife's egg.
What is the number of chromosomes found in a human ovum?
In an egg, there are 23 chromosomes, 2 of them being autosomes (sex cells).
What happens to the chromosomes when more cells are produced?
As a new baby grows, more cell must be made. This happens by the process of cell division. Each new cell has its own set of chromosomes carrying exactly the same information as the original fertilized cell.
Why is the ratio of male to female births roughly 50-50?
Human females have two X chromosomes (XX), while males have an X chromosome and a Y chromosome (XY). During meiosis, these chromosomes segregate into separate gametes. All female ova carry a single X chromosome, while in males, half the sperm carry an X chromosome and half carry a Y chromosome. When these fuse together during fertilization, 50% of the time a sperm with an X will fuse with an ovum carrying an X, to generate an XX individual (female). The other 50% of the time, a sperm with a Y fuses with an ovum carrying an X to generate an XY individual (male). Hence, the 50-50 ratio of males to females is a direct result of half of male sperm carrying an X chromosome and half carrying a Y chromosome.
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
