About the same 20-30,000 genes, although their genome sizes can be very different.
The types of proteins that are found in yeast cells are very similar to those also found in the human body. That is why it is sometimes difficult for our body's immune system to detect them and fight them off.
Humans have 23 pairs of chromosomes. 22 pairs are homologous (basically same shape) and the last pair is known as the X and Y sex-determining chromosomes. You were correct that 23 come from mom and the other 23 from dad. With regard to the question about genes, scientists finished sequencing the human genome in 2003. They found that the genome contained only 20,000-25,000 genes. You can read more about it if you search for human genome project on the net.
If the cells are from one individual, all will have the same genes except their sex cells which have 1/2 the number. A dog will have different genes from a cat. The genes make the cat different from the dog and human.
HUMAN GENOME HAS AROND 30,000 GENES
Human males' genes are more similar to the genes of human females than those of males of other species. Humans have 46 chromosomes; other species have other numbers of chromosomes.
there are 42 chromosomes in the human body
About the same 20-30,000 genes, although their genome sizes can be very different.
There are more genes than chromosomes in skin cells.
It was expected that we will find out about 1,00,00 different genes before Human genome mapping was done. In fact, we could find lesser number. Different books give different number but number is probably between 20,000 to 25,000. We got psychological depression, when we found same number of genes in round worm also.

I'm pretty sure than human and chimpanzees differ by 1%, that our DNA is 99% similar. Not sure but that's what I've heard
The human genome contains about 24,000 genes.

it is because they have genes
