The 2nd and 4th answer choices sound the best to me. I personally would go for the 2nd one, explaining that the fossils of fish K and fish R and Y are similar. If you get the question wrong, I am VERY sorry. :(

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.
