"Scientists estimate that there are between 20 000 and 25 000 genes in the human body" AQA Science GCSE Biology The human body has also 46 chromosomes which are completely different and shouldn't be muddled.
46
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.
Flies have the same type of DNA as we do. Except their genes are not the same. We don't need genes to make wings but they do. . They have 8 chromosomes and humans have 46. And humans and flies have 60% the same 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.
46
around 30,000-40,000 genes.
The Human Genome Project discovered that humans have about 24 000 genes.
Genes ARE heredity.
30,000
Most average humans have two copies of the p53 gene.
