What sex chromosome in a sperm cell must have fertilized an egg cell if a girl was produced?

Every egg has an X sex chromosome; a sperm can have either an X or a Y sex chromosome. If the sperm that fertilizes your egg has an X chromosome, you'll have a girl; if it has a Y chromosome, your baby will be a boy.

What chromosome must a sperm cell have to produce a male child?

Females have two X chromosomes in their cells, while males have X and Y chromosomes in their cells. Egg cells all contain an X chromosome, while sperm cells contain an X or a Y chromosome. This arrangement means that during fertilization, it is the male that determines the sex of the offspring.

Is XY chromosome male or female?

Typically, biologically male individuals have one X and one Y chromosome (XY) while those who are biologically female have two X chromosomes.

How many sex chromosomes are present in a human sperm cell or egg cell group of answer choices?

Human cells that contain one set of 23 chromosomes are called gametes, or sex cells; these eggs and sperm are designated n, or haploid.

What does XY means in pregnancy scan?

The mother's egg is always an X, while the father's sperm carries either an X, which means you'll be having a girl (XX), or a Y, which makes for a little boy (XY). At about week four gestation (six weeks' pregnancy), your baby-to-be starts to develop the beginnings of his or her genitalia.

What is the meaning of XY in gender?

The X and Y chromosomes, also known as the sex chromosomes, determine the biological sex of an individual: females inherit an X chromosome from the father for a XX genotype, while males inherit a Y chromosome from the father for a XY genotype (mothers only pass on X chromosomes).

Is there a YY gender?

Males with XYY syndrome have 47 chromosomes because of the extra Y chromosome. This condition is also sometimes called Jacob's syndrome, XYY karyotype, or YY syndrome. According to the National Institutes of Health, XYY syndrome occurs in 1 out of every 1,000 boys.

How many chromosomes do egg and sperm cells have?

It is a two-step process that reduces the chromosome number by half—from 46 to 23—to form sperm and egg cells. When the sperm and egg cells unite at conception, each contributes 23 chromosomes so the resulting embryo will have the usual 46.

Why do sperm and egg have 23 chromosomes?

One set of 23 comes from mom and the other 23 from dad. The egg and sperm cells are an exception--they have only 23 chromosomes each. A sperm from the man combines with a woman's egg in her womb to make a zygote. The zygote ends up with a total of 46 chromosomes and can now grow into a baby.

How many chromosomes do egg cell and sperm cell have?

Almost all the cells in your body have 46 chromosomes. There are two types of cells that are different. These are the eggs in a woman and the sperm in a man. They only have 23 chromosomes each.

What does XY chromosome represent?

Males have two different kinds of sex chromosomes (XY), and are called the heterogametic sex. In humans, the presence of the Y chromosome is responsible for triggering male development; in the absence of the Y chromosome, the fetus will undergo female development.

What does Y mean in ultrasound?

As the Y chromosome is male-specific, the detection of a Y chromosome is indicative of a male child. If foetal DNA is detected without a Y chromosome it is indicative of a female child.

How do you make a baby xx?

Men determine 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).

Can a girl have XY chromosomes?

The X and Y chromosomes are called “sex chromosomes” because they contribute to how a person's sex develops. Most males have XY chromosomes and most women have XX chromosomes. But there are girls and women who have XY chromosomes. This can happen, for example, when a girl has androgen insensitivity syndrome.

Can humans have 47 chromosomes?

Humans have 23 pairs of chromosomes. A trisomy is a chromosomal condition characterised by an additional chromosome. A person with a trisomy has 47 chromosomes instead of 46. Down syndrome, Edward syndrome and Patau syndrome are the most common forms of trisomy.

Do males have XY chromosomes?

The X chromosome is one of two sex chromosomes. Humans and most mammals have two sex chromosomes, the X and Y. Females have two X chromosomes in their cells, while males have X and Y chromosomes in their cells. Egg cells all contain an X chromosome, while sperm cells contain an X or a Y chromosome.
