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.
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.
What is the probablilty that a human sperm cell will carry an X chromosome?
The male gamete is comprised, on average, of 50% of the X chromosome and 50% of the 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.

Do human cells have 46 genes?
No. The human cell has 23 chromosome pairs (total 46 chromosomes). Each chromosome has many genes.
How is the haploid chromosome number?
The haploid chromosome number is half the chromosome number of the body cells. For example, in humans, body cells have 46 chromosomes. In human haploid cells (sex cells), there are 23 chromosomes.
How are the human sex cells chromosomes labled?
x chromosone and y chromosome
