A scientist working in an IVF (in vitro fertilization) clinic mistakenly produced a human zygote with 45 chromosomes. What biological process could explain how this happened? Group of answer choices failure of an egg to complete meiosis II failure of the egg nucleus to be fertilized by the sperm a non-disjunction in meiotic anaphase occurring in either an egg or sperm incomplete cytokinesis during spermatogenesis after meiosis I 2.

During the cleavage stage, this process takes the zygote from a single celled organism to multicellular morula. Question 8 options: Oogenesis Spermatogenesis Cytokinesis Mitosis Meiosis
"Meiosis, oh meiosis, let me tell you what it means. It's a special kind of cell division with some funny little genes. It starts with a cell splitting in two, just like mitosis would; but from there, things get wild and wacky, and I'll tell you if I could. Instead of dividing once more, the cells each split again; creating four brand new cells, not just two like back then. And here's where the magic happens, with chromosomes all pairing up, then swapping bits of info, a dizzying process that can't be summed up. When all is said and done, those four new cells are not quite the same; they've got half the number of chromosomes, and a whole new genetic game. Meiosis, oh meiosis, it's a puzzle that's so much fun. And if you study it like I have, you'll see how it all gets done!"

Define the following terms: Autosomes Sex Chromosomes Gametes Gonads Meiosis Mitosis Sertoli Cells Haploid Diploid
Meiosis is relatively rare and mitosis is relatively common. Which of the following makes meiosis different from mitosis? Meiosis produces DNA-less cells. We don't fully understand meiosis mechanisms. All gametes are diploid, whereas daughter cells from mitosis are haploid. The resulting cells (gametes) are haploid.
