how does mutations in metanephric mesenchyme affect gamete formation
Step by step
Solved in 2 steps
- Where does meiosis occur in males? Why are each of these stages important in sexual reproduction? Where does meiosis occur in males?explain in simpler words how does mutations in metanephric mesenchyme affect gamete formationWhy is it risky for a haploid sperm cell to go through diffrencition after meiosis?
- Oogenesis in the female results in one functional gamete—the egg, or ovum. What other cells are produced? What is the significance of this rather wasteful type of gamete production—that is, production of a single functional gamete instead of four, as seen in males?Describe the development of an oocyte from primordial follicle to when it is released at ovulation. How do hormones contribute to this progression? Describe the development of a spermatogonia to a spermatozoa. How do hormones contribute to this progression? What is the function of Sertoli and Leydig cells?What is the most significant difference in the process of gametogenesis comparing oogenesis with spermatogenesis?
- what is asexual reproductionFigure 43.15 Which of the following statements about hormone regulation of the female reproductive cycle is false? LH and FSH are produced in the pituitary, and estradiol and progesterone are produced in the ovaries. Estradiol and progesterone secreted from the corpus luteum cause the endometrium to thicken. Both progesterone and estradiol are produced by the follicles. Secretion of GnRH by the hypothalamus is inhibited by low levels of estradiol but stimulated by high levels of estradiol.What are the Consequences of Inversions during Gamete Formation ?
