Question

life cycles of sexually producing organisms involve the alternation of haploid and diploid stages true/false

Answer 1

Answer:

True

Explanation:

The life cycles of sexually producing organisms generally involve alternation between the haploid and diploid generations.

Sexual reproduction involves the fusion of gametes - fertilization. The gametes are haploid (n) and are usually formed by the reductional division (meiosis) of diploid (2n) sex cells.

Haploid gametes represent the haploid stage of the life cycles of sexually reproducing organisms.  During fertilization, the male and female gametes fuse together to form a diploid zygote. The zygote then continues to divide equationally (mitosis) and differentiates to give rise to a baby and eventually to either male or female adult organism.
