New genes appear in individuals by random mutation.
They have different genes just as humans do.
If crossing over didn't happen during meiosis in humans, the haploid daughter cells would all have the same genes. The crossing over creates variation and causes each daughter cell to have slightly different genes.

that means they are not identical twins they are fraternal they each got different genes
different form of genes are called allele
Sort of, different genes are activated at different stages of body growth and in different tissues.
Different types of genes are called alleles, which are alternate forms of the same gene that can produce variations in a trait. Additionally, there are also different categories of genes such as regulatory genes, structural genes, and non-coding genes that play various roles in controlling different biological processes.
Genes that are hidden when paired with a different allele in genetics are called recessive genes.
genes are the traits past down to their offsprings.
Dominant genes express themselves, phenotype depends upon genes .
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.
