Is the smallest gene cell chromosome?
Chromosome 21 is the smallest human chromosome. Inside of the chromosome, there are 48 billion nucleotides, the building blocks of DNA.
What determines the sex of a human?
Whether they have 2 X chromosomes= girl, of one X chromosome and one Y chromosome= boy
Which cell only contains one sex cell?
Gametes (sperm and eggs) contain only one sex chromosome.
How many chromosome does a mature skin cell in male human individual contains?
46
How many chromosome's are in one ovum?
It has 23 chromosomes. The fertilizing sperm has 23 as well so that together the resultant human has the normal 46 chromosome number.
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.
If an egg cell contains 50 chromosome how many chromosome are in a sperm cell from the same species?
50
Why is a human cell containing 22 autosomes and a y chromosome a sperm?
Human somatic (body) cells contain two sets of 23 chromosomes. Human gametes (sperm and egg cells) contain one set of 23 chromomes -- 22 autosomes and 1 sex chromosome. Only a sperm cell can carry a y chromosome. A sperm cell can also carry an x chromosome. The ovum can carry only an x chromosome, never a y chromosome. So a cell containing 22 autosomes and a y chromosome must be a sperm cell.
Are children born male or female or is it decided at a later time as suggested by the gender schema?
It is actually decided at a earlier time, at conception. It depends on the chromosome in the sperm. If the sperm contains a X chromosome it will be female(all eggs contain an X chromosome) and if it contains a Y chromosome it will be male.
What percent of human sperm Cells carry a pair of X chromosomes?
Human sperm does have chromosomes, in fact it has 23 of them, but they are not paired. The human sperm is a haploid cell meaning that it contains half of the chromosomes of most other cells (23), while most of the other cells of the body are diploid cells which contain 46 chromosomes. Sex is determined by the combination of the X chromosome donated by the mother, and either the X or the Y donated by the father. XX makes a girl, while XY makes a boy. While the egg normally always contains an X chromosome, and the sperm can have either an X or a Y chromosome, neither the sperm, nor the egg contain "a pair" of X chromosomes.
What is the probabitily that a human sperm cell will carry an x chromosome?
50%
What sex chromosome is found in human egg cell?
By human egg cell I guess you mean the oocyte (the one produced by the mother). The oocyte always carries the X chromosome, the sperm can either carry the Y or the X chromosome. Interestingly, the sperm which carries the Y is actually quicker than the one carrying the X, maybe because the X chromosome is far larger. So, if the Y chromosome sperm reaches the egg first, the child will be a boy (XY), and if the X chromosome sperm beats him to it, the child will be a girl (XX).
Do normal sperm or egg cells in a human have one copy of each chromosome?
Yes.
How many different kind of sperm?
Two, sperm that has an X chromosome and sperm that has a Y chromosome, all things being normal all sperm have the same chromosome count.
Name the 2 human gametes and tell their chromosome number?
The human gametes are Male gametes are sperm and female gametes are eggs. And the gametes chromosome numbers are 42.
What determines the sex of the human?
The genes that are carried in the sperm to the ova. If the 23rd chromosome of the sperm is 'X', the offspring will be female. If it is 'Y', the offspring will be male.
What percentage of human sperm Cells carry an X chromosome?
50 % of human sperm Cells are an X chromosome, the other half are a Y chromosome: {diploid = 2n = 1 chromosome pair; haploid = n = 1 chromosome - including the meiotic single chromosome = n}. All sperm and egg Cells carry one set each of n (23 single) chromosomes. When a sperm and an egg combine either: a) a sperm Cell with the X chromosome merges with the [X-chromosome] egg Cell and the baby will be a girl; or b) a sperm Cell with the Y chromosome merges with the egg Cell and the baby will be a boy.
