Every chromosome is a different size so the number of base pairs is different for each chromosome.
X chromosome has more that 153 million base pairs (greater that 306 million bases)
Y chromosome has around 50 million base pairs (around 100 million bases)

Why is a human cell containing 22 autosomes and a y chromosome a sperm?
A human sperm cell carries half the number of chromosomes as a somatic cell, contributing 22 autosomes and either an X or a Y chromosome. The Y chromosome is essential for determining male characteristics, making the cell a sperm.
How many chromosomes would a Trisomic human cell contain?
A trisomic human cell would contain 47 chromosomes instead of the usual 46. This is because one extra chromosome is present in one of the pairs.
What is a complete list of nucleotide sequence in a individuals chromosome?
It is not possible to provide a complete list of nucleotide sequences on an individual's chromosome in a single answer, as each chromosome contains millions of nucleotides. The human genome has over 3 billion base pairs, which make up the DNA on 23 pairs of chromosomes. The sequence can vary between individuals due to genetic variations.
What is the chance that a human zygote will receive one X and one Y sex chromosome during fertilization 100 percent 25 percent 75 percent 50 percent?
The chance that a human zygote will receive one X and one Y sex chromosome during fertilization is 50 percent. This is because an individual inherits one sex chromosome from each parent, with the father contributing either an X or a Y chromosome, and the mother contributing an X chromosome.
What portion of the human Y chromosome is homologous to the human X chromosome?
The pseudoautosomal regions (PARs) at the tips of the Y chromosome are homologous to regions on the X chromosome. These PARs are responsible for pairing and recombination between the X and Y chromosomes during meiosis. About 5% of the Y chromosome is homologous to the X chromosome in humans.
How many chromosome's do human body cells contain?
21
Does sperm contain x and y chromosome?
In humans the male sperm contains EITHER an X chromosome, or a Y chromosome since human gametes are haploid (n) in chromosome number.
What single attribute determines that a human fetus is male?
The presence of a Y chromosome.
What sex chromosome does a human egg cell contain?
The sex chromosome typically carried by an ovum is X-chromosome. The sperm may carry either x or y sex chromosome.
Does an entire chromosome code for only one gene?
You have about 20,000 to 25,000 genes in 23 chromosomes in human cell. So approximately 1000 genes are there in any single chromosome. The gene will be too big in size, if you have one single gene in any single chromosome.
Why is a human cell containing 22 autosomes and a y chromosome a sperm?
A human sperm cell carries half the number of chromosomes as a somatic cell, contributing 22 autosomes and either an X or a Y chromosome. The Y chromosome is essential for determining male characteristics, making the cell a sperm.
How do the chromosomes in human sperm cells differ from those in ova?
Human sperm cells contain 23 chromosomes, including one sex chromosome (either X or Y), whereas human ova contain 23 chromosomes, including one X sex chromosome. This difference in sex chromosomes contributes to the genetic diversity of offspring.
What might happen if human chromosomes did not separate?
well if human chromosomes number 21 does not separate during fertilization the baby will be with down syndrome. at fertilization of the egg with a normal sperm the zygote contain three chromosome number 21 (trizomic 21) hence the zygote contain 47 chromosome instead of 46.
How many genes do cells obtain?
The number of genes varies from chromosome to chromosome and the number of chromosomes varies from species to species (from as few as 1 single chromosome per cell to as many 30,000 chromosome pairs per cell). Human cells have 23 chromosome pairs per cell.
The male human is represented by sex chromosome of what?
The male human is represented by a sex chromosome consisting of one X chromosome and one Y chromosome (XY).
What is the 2n chromosome number for your skin cells?
The 2n chromosome number for skin cells is 46. This means that skin cells, like most human cells, contain 23 pairs of chromosomes.
Female sex cells contain a 1 X chromosome b 2 X chromosomes c 1 Y chromosome or d None of these and why?
All human female egg cells contain X chromosomes, each cell only contains one chromosome. The male sperm cells can contain either an X or a Y chromosome (one or the other, not both). That is what determines the sex of the child, two Xs and its a girl, one x and one y and its a boy. -X
