Why it is important for animals to reproduce sexually?

Answer 1

For external reproduction, plants that live in moist environments, need water to transport their gametes to enable sperm and egg cells to meet.

For internal fertilization, the water holds enough nutrients to support and hold the embryo in the female.

Answer 2

The advantage of sexual reproduction over asexual reproduction is the ability to create a diversity in properties of the offsprings.

While In asexual reproduction the genetic properties of the parent are inherited as is to the offspring, in sexual reproduction half of the genetic load comes from the one parent and the second from the second parent.

Another source of diversity is the fact that in the process of meiosis and creation of germ cells (egg, sperm) there is a process of recombinations that also increase the diversity of sexual reproducing species.

Answer 3

Sexual reproduction increases genetic diversity within a species, which can enhance its ability to adapt to changing environments. This diversity also helps reduce the likelihood of genetic diseases being passed on to offspring. Additionally, sexual reproduction allows for the shuffling and recombination of genes, potentially creating individuals with advantageous combinations of traits.

Answer 4

Water has nutrients to support the embryo and it ensures that the embryo doesn't lose moisture so it won't dry out.
