Quizplus · Accepted Answer

A zygote is the result of fusion of two haploid gametes, meaning that it contains a full complement of DNA from both parents. In this graph, Sample I has the highest DNA content, indicating that it contains the most genetic material and therefore could represent a zygote. Samples II and III have lower DNA content, suggesting they may represent different cell types with fewer chromosomes or less genomic DNA.
