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.

∙ 15y agoBoth have an x chromosome. Girls are XX and boys are XY.
Wiki User
∙ 11y agoThe SRY ( sex determining region ) control gene on the male, Y, chromosome determines the sex of the fetus.
Googly sex determining region for more info.

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
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 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.
Which cell decides the sex of the baby the sperm cell or the egg cell?
Genetically, the contributions of the two parents are almost identical.Both the sperm and the ovum contribute the same amount of genetic information on nuclear chromosomes. They each contribute a haploid number of chromosomes (i.e. one set of 23 chromosomes).However, a few genes (37) are carried on the mitochondrial DNA (mtDNA), of which there are hundreds of copies in a typical cell. All the baby's mtDNA comes from Mum; Dad supplies only nuclear DNA. So the mother contributes a few more genes to the child than the father does.
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?
A child's sex is determined if he has XY chromosomes or she has XX chromosomes. So in general the statement is true.
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.
Do genes on a chromosome determine whether a baby is a boy or a girl?

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
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.

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.
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.
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.
What does each parent give to there genes?
When an egg and a sperm "unite", they form a zygote, which has two gender chromosomes. However, eggs and sperm by themselves only have one. Eggs only ever have X chromosomes. Sperm can either have X or Y chromosomes. If an X sperm enters the egg, it will be XX or female. If a Y sperm enters the egg, it will be XY or male. This isn't really taking into account chromosomal disorders such as XXY etc where things don't go quite as expected, but that's the basics of things. It's pretty random which sperm will "win", there's no real way to determine that. I think studies have shown that in some families/men female sperm are dominant, or male sperm, so that families sometimes have a run of girls before having a boy, etc.
