3. most animals and plants reproduce sexually. this means that dna is passed down to new organisms from two parental organisms
which of the following is a key advantage of sexual reproduction?
a. increased genetic diversity for changing environments
b. the creation of new genes to improve survival
c. the receipt of the strongest genes from both parents for survival
d. the elimination of genetic mutations from a parent organism

The correct option is A.

Explanation:

There are two basic types of reproduction, they are asexual and sexual reproduction. Asexual reproduction involves the division of a mature organism into two different organisms through binary fission or other forms of asexual reproduction. In this case the offspring is similar both physically and genetically to the parent organism. There is no genetic diversity in this case and the same disease can easily wipe out the entire population of the organism.

Sexual reproduction on the other hand requires two different organisms. During the reproductive process the genetic materials from the two organisms get mixed up thoroughly, so they end up giving birth to offspring that are quite different from them genetically.

The diversity in genetics makes it possible for the offspring to cope with changing environmental conditions. Because, the offspring are diverse in constitution, some offspring will always be able to survive harsh environmental conditions due to their genetic make up.  

The Option A is correct i.e.

Sexual organisms increases genetic diversity for changing environments

Explanation:

Reproduction is the biological process by which new organisms are produced from their parents.  

In asexual reproduction, an organism can reproduce without the involvement of another organism. By asexual reproduction, an organism creates a genetically similar or identical copy of itself.  

Sexual reproduction typically requires the sexual interaction of two specialized organisms, called gametes, which contain half the number of chromosomes of normal cells and are created by meiosis, with typically a male fertilizing a female of the same species to create a fertilized zygote. This produces offspring organisms whose genetic characteristics are derived from those of the two parental organisms.

The diversity in genetics makes it possible for the offspring to cope with changing environmental conditions. Because, the offspring are diverse in constitution, some offspring will always be able to survive harsh environmental conditions due to their genetic make up.
