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.
What else can I help you with?
Do genes on a chromosome determine whether a baby is a boy or a girl?
yes particular one's do which are the xy chromasones
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 an embryo with 2 X chromosomes develop into a female?
An embryo with 2 X chromosomes develops into a female due to the presence of genes on the X chromosomes that promote the development of female reproductive structures and characteristics. These genes lead to the production of hormones that guide the development of female features during prenatal development.
If your husband has a lot brothers will you birth a lot of sons?
No. The gender of the baby is always a 50/50 chance. Females have two X chromosomes, while males have one X and one Y. If the father gives the X chromosome, then the baby will be a girl (XX) but if the father gives a Y chromosome then the baby is a boy (XY). Whether he gives an X or a Y is completely random.
How many chromosomes are in a baby's umbilical cord cell?
There are 46 chromosomes in the umbilical cord.

Is this sentence true or false. Genes on chromosomes determine whether a baby is a boy or girl?
True. The presence of certain genes on the sex chromosomes, specifically the Y chromosome, determines the sex of a baby. An individual with XY chromosomes will develop as a boy, while an individual with XX chromosomes will develop as a girl.
What decides if a baby going to be a boy or a girl?
The chromosomes in the sperm determine whether the baby is going to be a girl or boy.
How do X and Y chromosome differ?
The X chromosome is larger and carries more genetic information than the Y chromosome. The Y chromosome carries the genes that determine male sex characteristics, while the X chromosome carries genes that are important for both male and female development. Males typically have one X and one Y chromosome, while females have two X chromosomes.

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.
Does XY combination of chromosomes give a female baby?
No, XY combination of chromosomes produces a male baby. To produce a female baby, the combination of chromosomes must be XX. The mother's egg is always X, so the deciding vote goes to the father's sperm to choose an X or a Y chromosome - to see whether we'll be a boy, or a girl.
Which parent determimes the baby's blood type?
The alleles for Immunoglobulins are carried on autosomal chromosomes, not on sex chromosomes. Hence, both parents are equally responsible for a baby's blood type.
In plants and animals an offspring inherits How Many genes?
The number of genes and number of chromosomes inherited depend on the species. The number of chromosomes a species has is known as the chromosome number. For example, (disregarding polyploidy or polysomy) a human baby has 46 chromosomes, but a horse has 64. Chromosomes usually occur as one of a pair in humans, and so they have 23 pairs of chromosomes. However, it is common in plants to have many sets of chromosomes and so they do not occur in pairs, but in triplets, or as sets of 4, 5 or 6 etc. Some species of strawberries have 7 of each chromosome. The number of genes depends on how long the chromosome is, and each chromosome in each different species will have a different number of genes on the chromosome.
Why arent child re identical to either one of their parents?
Children share the traits of each parent. Each parent provides 26 chromosomes to the baby and DNA for the developing fetus. There are dominant and recessive genes that determine things like eye and hair color, so when a baby is born they have a combination of both parents DNA.
