What is a karyotype and what two things can be determined from it?
A karyotype is the number, forms, and types of chromosomes in a cellDetermine whether the chromosomes of an adult have an abnormality that can be passed on to a child.Determine whether a chromosome defect is preventing a woman from becoming pregnant or causing miscarriages.Determine whether a chromosome defect is present in a fetus. Karyotyping also may be done to determine whether chromosomal problems may have caused a fetus to be stillborn.Determine the cause of a baby's birth defects or disability.Help determine the appropriate treatment for some types of cancer.Identify the sex of a person by determining the presence of the Y chromosome. This may be done when a newborn's sex is not clear.
Why does the father ultimately determine thesex if the baby?
The sex of a child is determined by the father because the genes that determine sex come from the male sperm.
What sex chromosome does a male have?
The male sex chromosome is XY, and females are XX. The X comes from the female, and an X or a Y from the male. When they meet, that determines whether the baby will be a boy or a girl.
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.
Are genes on chromosomes determine whether a baby is a boy or a girl?
A man can produce X and Y chromosomes, each sperm cell has either of these two ( X or Y) which, during intercourse, fuses with an egg (can only be X). This means that the two possibilities are either XX or XY for the resulting foetus. A male child will have the arrangement XY, and a female child will have the arrangement XX.

How do X and Y chromosome differ?
men have a x and y chromosome while women have two x chromosomes the y chromosomes determine the sex of the baby
Because the X chromosome contains genes that are vital for normal development no baby has been born?
without an X chromosome
What can karyotypes determine?
Determine whether the chromosomes of an adult have an abnormality that can be passed on to a child.Determine whether a chromosome defect is preventing a woman from becoming pregnant or causing miscarriages.Determine whether a chromosome defect is present in a fetus. Karyotyping also may be done to determine whether chromosomal problems may have caused a fetus to be stillborn.Determine the cause of a baby's birth defects or disability.Help determine the appropriate treatment for some types of cancer.Identify the sex of a person by determining the presence of the Y chromosome.

What is 2 ways a karyotype can be used before a baby is born?
It is used to determine the sex of the baby and also to determine any abnormalities in chromosome.
Is this sentence true or false. Genes on chromosomes determine whether a baby is a boy or girl?
A child's sex is determined if he has XY chromosomes or she has XX chromosomes. So in general the statement is true.

Are you more likely to have a boy if the father's family are all boys?
It is the sperm that fertilizes the egg that will determine the sex of your baby. Some sperm carry the X-chromosome and some sperm carry the Y-chromosome. If an X-chromosome-carrying sperm fertilizes the egg, the baby will be a girl. If a Y-chromosome-carrying sperm fertilizes the egg, the baby will be a boy.
Is the father gene that decides whether the baby is a boy or a girl?
Yes it is from the father that this comes but not at the level of a single gene. The genes that determine sex are to be found on the sex chromosomes, of which every person has two. They come in two types X and Y. Woman have an XX pair and Men have an XY pair. Thus as you can see the Y chromosome is that which makes the difference and this comes from the man.
How do you determine to give birth to a male?
You cannot control the sex of a fetus through determination alone. The mother donates an X chromosome via her egg. The sperm donated by the male partner, which can contain an X or Y chromosome, determines the sex of a baby depending on whether their sperm is carrying an X or Y chromosome. An X chromosome combines with the mother's X chromosome to make a baby girl (XX) and a Y chromosome will combine with the mother's to make a boy (XY).http://www.science20.com/news_releases/chromosomes_are_so_20th_century_male_genes_really_determine_baby_gender_says_study#ixzz3eHLpJJRt
What is the functional unit of information on the chromosome?
NO. . the functional unit of genetics is the gene. . and a single chromosome may contain 100's of genes in it.. . vegi.chaitanya@gmail.com
What kinds of food need to have to get a baby girl?
Only the x or y chromosome will determine gender. food will have no influence.
