A zygote contains a full set of genes, which typically includes about 20,000 to 25,000 genes in humans. These genes come from the genetic material contributed by the sperm and egg during fertilization.
If an organism has XX genes, it is typically female in species where females have two X chromosomes, such as in humans and many mammals.
No. The human cell has 23 chromosome pairs (total 46 chromosomes). Each chromosome has many genes.
False. Skin color in humans is a complex trait that is influenced by multiple genes, not just one pair of genes or alleles. Many factors, including genetic, environmental, and evolutionary influences, contribute to the wide range of skin colors observed in human populations.
The number of genes varies. Most of any chromosome consists of non-coding DNA, which does not contain any genes. Each chromosome has many chromatins. One gene consists of many chromatins. Therefore, one chromosome could have many genes.
Thousands
Humans have a total of 23 pairs of genes, for a total of 46 individual chromosomes.
Humans have about 20, 000 to 25,000 genes.
around 30,000-40,000 genes.
The Human Genome Project discovered that humans have about 24 000 genes.
30,000
Most average humans have two copies of the p53 gene.
Different animals have different numbers of genes (and chromosomes). The exact number of genes that animals have has not been proven for many species, so estimates have been made. It is estimated that humans and mice have approximately 20,000 genes, roundworms have approximately 13,000 genes and yeast has around 6,000 genes. It should be noted that, similar to chromosome number, a larger number of genes does not necessarily mean the organism is more complex - for example rice has over 46,000 genes.

~ 25,000 genes but Scientist lower this number as more is known.
