Which statement is true regarding sexual reproduction as a method of producing offspring?
a. it is uncommon among mammals.
b. it is not usually a method used by plants
c. it produces offspring that are genetically identical
d. it requires more resources and time than asexual reproduction.

The correct answer would be d. It requires more resources and time than asexual reproduction.

Sexual reproduction is a type of reproduction in which two organisms of opposite sex are involved. The gametes produced by each parent fertilized or fused with each other to form a zygote.

The zygote then develops into the offspring by passing through various embryological stages.

It is a common method of reproduction in eukaryotic organisms such as plants, animals et cetera.

The genetic make of the offspring is made by the combination of the maternal and the paternal genome. In addition, crossing over also takes place during the formation of gametes. These factors provide the genetic diversity to the population.

One of the major drawbacks of the sexual reproduction is that it is a time and energy consuming process. It requires two parents and number of offspring is also less as compared to the asexual reproduction.

Hence, we can conclude that sexual reproduction requires more resources and time than asexual reproduction.
