It's essentially impossible to answer this question, because there are lots... indeed, an infinity... of potential genes that could be part of the human genome but are not.
One of them, for example, is the gene that would enable humans to synthesize vitamin C. Most mammals have it; humans, bats, guinea pigs, and a few monkeys don't.
We call these sex chromosomes. Whether you are a male or female depends on the presence or absence of certain chromosomes. The sex chromosomes are the X chromosome and the Y chromosome. If you have two XX, you will show female characteristics and If you have XY you will show male characteristics.
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.
No, there are 46 chromosomes in one cell. A gamete, or sex cell, has 23 chromosomes because during fertilization, the female and male gametes (egg and sperm, respectively) come together to form a new cell with 46 chromosomes
Each human chromosome is typically replicated in multiple sections called replication origins. These origins are sites along the chromosome where the DNA double helix unwinds and new DNA strands are synthesized during DNA replication.
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.
The male human is represented by a sex chromosome consisting of one X chromosome and one Y chromosome (XY).

Chromosome#19 is autosomal cell when refering to the human system. The #23 chromsomes is the sex cell in the human body system.
The proportion of paternal chromosomes in a human skin cell is 50 percent.

No. The human cell has 23 chromosome pairs (total 46 chromosomes). Each chromosome has many genes.
The human male has both an X and Y chromosome which determines the sex of an offspring. Female only have the X chromosome.

46.
The sex chromosome typically carried by an ovum is X-chromosome. The sperm may carry either x or y sex chromosome.
