There is inherited diversity.
The same way they do today, by sexual reproduction.
Repair damaged DNA.
Sexual reproduction likely evolved before the first multicellular organisms appeared. It is believed to have originated in single-celled organisms as a way to increase genetic diversity and adaptability. The transition to multicellularity then allowed for more complex forms of sexual reproduction to develop.
With asexual reproduction, the DNA creates a total copy, unique in no way whatsoever. However, with sexual reproduction, though the process is not as quick in most cases, there is a certain level of unique traits which allow the offspring to either spread into different areas, as most plants do, or become a better or worse version of the combination of its two parent genes. Also, in most animals and humans, sexual reproduction is rather pleasurable.
Mitosis is the most common way of algae reproduction.
With sexual reproduction, each generation is slightly different from either parent. That way in every species some members are likely to survive and reproduce when conditions change. Asexual reproduction can occur at a much faster level than sexual reproduction. With some plants, a branch stuck in the soil will produce a new plant. That happens much faster than waiting for a seed to grow.
the same way humans do
There are 2 types of reprodution , those are sexual and asexual reproduction . Sexual reprodution invloves both a male and a female . but asexual reproduction involves just the female ( a good example of this is a plant , some plants do not need others to reproduce ) ! Hope that helps :)
Meiosis isn't reproduction itself but takes place during sexual reproduction. The function of meiosis is to produce haploid gamete cells that way when fertilization occurs the result are two haploid gametes (half the number of chromosomes) coming together. It occurs only during spermatogenesis or oogenesis, mitosis produces normal somatic cells.
Conjugation is a primitive form of sexual reproduction in bacteria where genetic material is transferred between two cells through a bridge-like structure called pilus. This allows for genetic diversity and the exchange of beneficial traits between bacterial cells.
No. Nothing has ever been found that can influence sexual orientation.
The vast majority of animals use sexual reproduction to reproduce. Sexual reproduction involves two parents, a male and a female who combine egg and sperm. There is also asexual reproduction, where an organism multiplies or produces an off spring without a mate. Bacteria, for example, goes through binary fission, where it makes an identical copy of its cell, or multiple fission, where there is more than two offspring.I'm not sure how old you are, so umm.... The same way humans do. If you don't know how humans do that; then you need to talk to someone.the vast majority of animals
