life cycles of sexually producing organisms involve the alternation of haploid and diploid stages true/false
kolbaska11 [484]

Answer:

True

Explanation:

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

<u>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. </u>

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.
