Summary Introduction
Introduction:
The sperms and eggs are the gametes of male and female respectively. The sperm is produced by the process of spermatogenesis and eggs are produced by the process of oogenesis. During fertilization, one sperm and one egg fuse together to form the zygote.

- "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!"arrow_forwardFor each of the following, identify what characteristics of a species male and female karyotype would indicate that mechanism of sex-determination.

- You are an allele on a single uncondensed chromosome in a Yellow fever-carrying mosquito (Aedes aegypti) diploid cell (2n = 6). Demonstrate in as much detail as possible: (1) how you will get to each genetically identical diploid cell of the multicellular offspring. (2) how you will get to the next generation of sexually reproduced progeny.arrow_forwardWhich of the following is NOT true while comparing internal to external fertilization. In external fertilization, zygotic DNA replication starts after the fusion of gamete pronuclei; in internal fertilization, the first zygotic DNA synthesis happens before pronuclei fusion. B Capacitation is only observed in internal fertilization. In both internal and external fertilization, the cortical granule reaction is required for the slow block to polyspermy. In external fertilization, intracellular calcium release is stimulated prior to gametes fusion; in internal fertilization, it happens after gametes fusion. In both internal and external fertilization, there is a slow and a fast block to polyspermy.arrow_forwardMitosis is used to make more body cells while meiosis is only used to make gametes for sexual reproduction.
