While the chromosomes for other parts of the body are the same size and shape — forming an identical pairing — the X and Y chromosomes have different structures. The X chromosome is significantly longer than the Y chromosome and contains hundreds more genes.

How does the chromosome X and Y compare?
The genes on the sex chromosomes and their downstream factors such as sex hormones act on the tissues of the body and produce the sex difference. ... The main difference between X and Y chromosome is that X chromosome is the female sex determining chromosome whereas the Y chromosome is the male sex determining chromosome.
What is the difference between X and Y sperm?
A spermatozoon is a male germ cell capable of fertilizing an oocyte and carries genetic information for determining the sex of the offspring. It comprises autosomes and an X (X spermatozoa) or a Y chromosome (Y spermatozoa). ... The only difference between X and Y spermatozoa lies in their DNA content.
How can you compare gene from chromosome?
Genes are segments of deoxyribonucleic acid (DNA) that contain the code for a specific protein that functions in one or more types of cells in the body. Chromosomes are structures within cells that contain a person's genes.
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.
Can you be a girl with a XY chromosome?
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.
What is the lifespan of Y sperm?
For a boy, sperm with the Y chromosome should be deposited as close as possible to the egg because the Y chromosome has a short lifespan and it will not live longer than 24 hours, compared with the sperm with the Y chromosome which will live in a woman's body for up to 72 hours.
What is chromosome BYJU's?
Chromosomes are the genetic material present in all cells. They are present in the nucleus of a eukaryotic cell. They are a thread-like structure. Each chromosome of a eukaryotic cell contains DNA and associated proteins, known as histone proteins.
What is the relationship between a chromosome and DNA?
The chromosomes serve as the structure that holds the DNA. The DNA acts as a complete set of instructions that tells our bodies how to develop. Storing more data than any computer, each chromosome contains all the information needed to give you a base for your physical (and emotional) characteristics.
Who is responsible for baby gender?
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).
How long Y sperm takes to reach egg?
It takes about 24 hours for a sperm cell to fertilize an egg. When the sperm penetrates the egg, the surface of the egg changes so that no other sperm can enter. At the moment of fertilization, the baby's genetic makeup is complete, including whether it's a boy or girl.
When will the Y chromosome disappear?
"So it doesn't take a great brain to realize that if the rate of loss is uniform — 10 genes per million years — and we've only got 45 left, the whole Y will disappear in 4.5 million years." Uniform is the key word here. More recent research suggests that the rate of degradation has slowed over time.
What is chromosome 10th?
Chromosomes are thread-like structures present in the nucleus. They are important because they contain the basic genetic material DNA. These are present inside the nucleus of plants as well as animal cells.
What are chromosomes Grade 9?
A chromosome is a DNA molecule that consists of a part or all of the genetic material of an organism. The chromosome is present in the nucleus of each cell, and it is packaged into thread-like structures. Structurally, each chromosome is composed of DNA that is tightly coiled around special proteins called histones.
