|
The reproductive process involving two parents whose genetic material is combined to produce a new organism different from themselves
|
|

The reproductive process in which a single cell makes a copy of itself

|
A characteristic that is passed from parent to offspring
|
Detailed explanation-1: -Sexual reproduction involves two parents and produces offspring that are genetically unique. During sexual reproduction, two haploid gametes join in the process of fertilization to produce a diploid zygote. Meiosis is the type of cell division that produces gametes.
Detailed explanation-2: -In sexual reproduction, an organism combines the genetic information from each of its parents and is genetically unique. In asexual reproduction, one parent copies itself to form a genetically identical offspring.
Detailed explanation-3: -Sexual propagation is the reproduction of plants by seeds. The genetic material of two parents is combined by pollination and fertilization to create offspring that are different from each parent. There are several advantages of sexual propagation: It may be quicker and more economical than asexual propagation.
Detailed explanation-4: -Sexual reproduction is the creation of a new organism by combining the genetic material of two organisms. As both parents contribute half of the new organism’s genetic material, the offspring will have traits of both parents, but will not be exactly like either parent.
